IR receiver signal not activating 12 v motor

Help & Support Robot Parts

Hi everyone, new to the Arduino world with the idea of building a projector lift. The hardware setup is as follows:-

  1. 240v ac -12v dc power supply connected to a 12 volt wiper motor, connected to a Cytron MD 10C.

I have the MD1O C connected to the Arduino UNO R3.
Arduino GND - MD10 C GND
Arduino int Pin 3 (~) - MD10 C PWM Pin
Arduino int Pin 2 - MD10 C DIR Pin

With a simple sketch I get the wiper motor to rotate both clockwise and counterclockwise with a (Pwm value ,50) so far so good.

However, when I connect an IR receiver to the Arduino via a breadboard using Pin 7 as the signal from the receiver with an updated sketch the motor fails to respond.

I have checked the voltage to the DIR pin and it is receiving 5v

What am I missing?

Constructed criticism welcome.

Hi,

It is not clear what the IR receiver is doing in the setup, are you using a remote to control to the motor?

Make sure you included the IRremote.h library inside your code:
