Just in case my connections to my motor were bad to the M1 output, I also tested with a volt meter to verify that no voltage was coming off the M1 outputs. I tried powering the Arduino then the motor shield etc. I tried powering the motor shield for a minute, then powering the Arduino to see if the order made a difference in the two making the i2C connection. I tried cycling the power on both Arduino and motor shield to see if it was a handshake or startup issue.

I tried them backwards, soldered pins to the A4 and A5 on the motor driver (in case I was misreading the documentation) and tested them to connect to the Arduino. I put the leads from the SDA and SCL pins on the motor shield to the A4 and A5 pins, the SDA and SCL pins in both permutations, as well as the pins labeled SDA and SCL on my Arduino Uno. To simplify my test, I have only one motor attached to the output labeled M1 on the motor driver and no other sensors or pins used by the Arduino except the two for SDA and SCL.Īs part of my numerous tests, I tried all of the permutations I can think of. I then downloaded the example DCMotorsTest (File->Examples->Adafruit_MotorShield->DCMotorTest in the Arduino IDE) into the Arduino Uno. For power to the Arduino, I used the USB cable connected to my laptop. I got a steady and what I consider bright green light on the LED on the motor driver. I removed the jumper for the Motor Power and applied the power leads from the separate supply as documented. I soldered two pins onto the SDA and SCL pins on the motor shield. Because of room and where this is going on my final project, I do not want to use this as a shield on the Arduino Uno. I also carefully read the section on 'What pins are/are not used on the motor shield?' I read that the SDA and SCL i2C pins are all that is needed to control the motors.

or-arduino) which very well documented how to install the library and what example software to get working. I verified that I am wiring the motor correctly based on your excellent documentation and clearly marked PCB.

I have a bright green LED from the motor driver while on a separate power supply, but for some reason the example code that comes with the library DCMotorsTest does not provide power to the motor one leads. I am unable to get it to work and am not sure what I am doing wrong. Yesterday, I had two of your motor shields arrive in the mail which I want to use to drive 4 small motors using a dc supply that puts out 7.5 - 8 volts and is rated for 2 amps of output. Beware: The Servo Pins on the Motor Shield (next to the reset button) do not work if you put the motor shield directly on the 'wemos d1 r2' Rules Example On Clock#Time=All,21:22 do // every day at 21.22 hours do. We currently support a maximum of two servo motors so you can build a pan & tilt device if you like.Įxample to set servo 1 on gpio-0 to a 90 degree position and servo 2 on gpio-2 to a 45 degree position: Support for Servo Motors is available via the buildtin functionality of ESPEasy (not part of this plugin) and can be done this way: You can control the Motorshield by remote http commands send from your Home Automation Controller or any other device that can send http get requests. Select 'Adafruit Motor Shield v2' from the dropdown box.Įnter the i2c address of you sensor, default value 0圆0Ĭontrolling the Motor Shield via HTTP commands Use the device tab on the ESP Easy webinterface and create a new task by editing one of the available tasks. The Plugin is heavily based on Adafruits own Library

Support the great developer of this board with buying it from them! (you will also find cheaper clones on Aliexpress, which also work with this plugin) This Plugin works with the v2 version of the Adafruit Motor Shield v2:

Wemos D1 R2) you have to set it to 3.3 V, see adafruit documentation for that. This Plugin is for the Adafruit Motor Shield v2 which is controlled over the I2C protocol. This Plugin in currently only available in the latest mega build github
