How to Fix Common Problems with Funduino Uno R3 Driver



hi everyone... i am facing a big problem here. i was using sansmart uno r3 for last onle year, it was working fine with no difficulties. but suddenly stop installing driver with my windows 7. i have reinstalled the arduino software so many times and tried to load the driver manualy but no luck. the list for drivers show just other device. can help me out.

You can see this on cheap Chinese Arduino clones; this chip will not be detected neither by your computer nor the IDE. You have to install CH340G driver to your computer only then your computer will recognize the device and able to upload sketches.


It worked well for the last few days but today i received after I wanted to upload a error that it is not connected. So I searched for the correct driver at the hardware manager, which I found after a longer time because all tutorials on the internet not worked for my problem. Then I got an error message "This device cannot start (Code 10)". And at this point I have no idea what i can do next to fix that.


As I wanted to install the driver you attached I saw that my arduino was detected as the old COM3 Port of the last days and it is working fine. I dont know how that happend but I am happy that my problem is solved.


The Arduino Nano has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega328 provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An FTDI FT232RL on the board channels this serial communication over USB and the FTDI drivers (included with the Arduino software) provide a virtual com port to software on the computer. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board. The RX and TX LEDs on the board will flash when data is being transmitted via the FTDI chip and USB connection to the computer (but not for serial communication on pins 0 and 1). A SoftwareSerial library allows for serial communication on any of the Nano's digital pins. The ATmega328 also support I2C (TWI) and SPI communication. The Arduino software includes a Wire library to simplify use of the I2C bus. To use the SPI communication, please see ATmega328 datasheet.


The Arduino Nano can be programmed with the Arduino software (download). Select "Arduino Duemilanove or Nano w/ ATmega328" from the Tools > Board menu (according to the microcontroller on your board). The ATmega328 on the Arduino Nano comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol. You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header using Arduino ISP or similar.


Primeramente deberás identificar el tipo de tarjeta que tienes. Si está basada en el chip CH340 es necesario instalar el controlador (driver) realizando el procedimiento que se muestra en esta página. Es fácil identificar el circuito de interfaz de tu tarjeta mirando el integrado que se encuentra junto al conector USB: El chip CH340G tiene el siguiente aspecto: Para las tarjetas originales y las compatibles que tienen una interfaz USB mediante ATMEGA16U2 NO es necesario instalar controladores por que ya vienen incluidos en el Arduino IDE.


El driver CH340G es el software requerido para operar el circuito integrado de la interfaz USB en varios sistemas operativos (Windows, Linux, MAC, etc.). Al momento de escribir esto, las tarjetas que pueden utilizar estos controladores son las siguientes:


These instructions describe an installation of the Arduino Software and drivers for an Arduino Uno on Mac OS X Lion, but will work the same for Leopard, Snow Leopard and Mountain Lion. Previous operating systems may require you to search the web for your specific situation.


1. Software von www.arduino.cc downloaden und auf dem PC installieren (Das Arduino-Board noch NICHT angeschlossen). Danach öffnet man den Softwareordner und startet das Programm mit der Datei arduino.exe.


The L293D is a dual-channel H-Bridge motor driver that can control two DC motors or a single stepper motor. Because the shield includes two such motor drivers, it can control up to four DC motors or two stepper motors.


The sketch below will show you how to control the speed and spinning direction of a DC motor using the L293D motor driver shield and can serve as the basis for more practical experiments and projects.


Ironically, not many people actually know how to work with them. And if you are a totally clueless beginner when it comes to electronics, we understand that reading through tons of technical jargon online can be rather daunting and off-putting at times. Hence, we have summarised a guide on how to interface a 28BYJ-48 stepper motor with an Arduino, using a ULN2003 driver board.


The ULN2003 is one of the most common motor driver ICs that houses an array of 7 Darlington transistor pairs, each capable of driving loads up to 500mA and 50V. A Darlington pair is a pair of transistors, where the second transistor amplifies the output current of the first transistor.


As shown in the diagram below, a ULN2003 driver board consists of a ULN2003 soldered onto a board, together with resistors, capacitors, and other bits and bobs that help create the circuit that takes the pulse signals from the controller and converts them into stepper motor motion.


The 28BYJ-48 stepper motor consumes high current and hence, we will need to use a driver IC like the ULN2003 in order to control the motor with a microcontroller like the Arduino. Known for its high current and high voltage capacity, the ULN2003 gives a higher current gain than a single transistor and enables the low voltage and low current output of a microcontroller to drive a higher current stepper motor.


For example, a stepper motor that needs 9V and 300mA to operate cannot be powered by an Arduino. Hence, we connect this IC to source for enough current and voltage for the motor. If you have to power anything more than 5V and 80mA, the ULN2003 driver board should be used.


Important note: By using this setup, we are powering the stepper motor directly from the Arduino. Although this is the simplest way to provide power to the motor, it is not recommended to do so (connecting the driver board VCC pin to the 5V pin of the Arduino).


The Arduino Integrated Development Environment (IDE), or Arduino software, comes pre-installed with a default stepper library. Hence, there is no need to download the library. On the first line of the code, we will first include the header file of this built-in stepper library.


Now that you have gotten a gist of how to operate the 28BYJ-48 stepper motor with the ULN2003 driver board and Arduino, have a browse at the Seeed Bazaar here, where you can find quality stepper motors, driver boards, and Arduino microcontrollers for your next project. Also, check out the stepper motor driver pack that comes with both the 28BYJ-48 stepper motor and a ULN2003 driver board at affordable prices.


Hi Helen.Thanks for the blog.I am new to stepper motors.I built up the same setup like you with the ULN2003 board, and using the Stepper library.As long as I dont call stepper.step(), the 28BYJ-48 consumes practically no current.But if I call send(), after the motor stops rotating, the power consumption jumps up to constant 370mA on 5V.Is this a problem with the Stepper driver?Thanks,Ivan


Hello HelenI am very inexperienced with electronics, I been looking this project and the one part that is missing is how to power the project.In this project I am guessing for power do I use a USB computer to Arduino?To power th 28BYJ-48 stepper motor through the ULN2003 driver board, can I use a battery source?


This article includes everything you need to know about controlling a 28BYJ-48 stepper motor with the ULN2003 driver board and Arduino. I have included datasheets, a wiring diagram, and many example codes!


If you want to learn more about controlling larger stepper motors with more torque and more speed, take a look at the articles below. In these articles I teach you how to control NEMA 17 stepper motors, with drivers like the A4988.


The Adafruit Industries Small Reduction Stepper Motor uses the same form factor as the 28BYJ-48, but does have a different gear ratio. It has a roughly 1/16 reduction gear set, which results in 513 steps per revolution (in full-step mode). You can download the datasheet for it here.


In this article I have shown you how you can control a 28BYJ-48 stepper motor with a ULN2003 driver and Arduino. We have looked at 4 examples, using both the Stepper and AccelStepper libraries. I hope you found it useful and informative. If you did, please share it with a friend that also likes electronics!


Im using the motor and driver specified here with an arduino nano and CANNOT get any coding to move the motor. The LED lights are on at full on the driver but theres no movement like its cycling through the phases. I have swapped two drivers and two motors to make sure the components aren't fried. When I hook the motor directly to the Nano I can feel it vibrating like its trying to move but it clearly is underpowered (which I know it is). When I have it connected back to the driver I am powering it with an external 5V 2.1A power supply.


I use this configuration with 1 driver/motor to rotate my Sony camera on a tripod mounted bracket. I use another driver/motor to tilt the bracket via a toothed belt and pulleys. This reduces the torque on the motor and gives me very smooth movement.These are connected tom a UNO3 board and I wrote an Android app to remotely control them via Bluetooth, and it all works well BUT with the lens at full zoom the motor isn't quite powerful enough to tilt the bracket up, so I sometimes have to zoom out a bit.Would it be possible/advisable to connect another motor to the driver that controls the tilt? I'm hoping this would give me twice the torque? If feasible is it just a case of splicing the cables or is there a neater way?
