DC Motor Control with IR Receiver and VNH2SP30 driver

Hi everyone,

I would like to control my dc motor with IR receiver and motor driver. I can control the dc motor in serial monitor user input. I use the code as below link. I can change motor speed to increase motor speed %10 with 4 input and to decrease 5 keyboard number. It works as well.

I have already bought IR Receiver then I would like to control motor speed volume button. I know each button are assigned hex code ir library for example vol+ button hex code is FD807F. I tried to merge two code which code as above link and this youtube video https://www.youtube.com/watch?v=uPbwEO5aL2w

I uploaded my code which has already merged but it doesn't work. How can we fix this code and use IR Receiver.

Thank you.

One bad thing in the code is: There are no comments telling the intention of the lines of code....

 digitalWrite(motorB1Pini, LOW);

What does "LOW" do? I don't spend time discovering that...

5

this motorB1Pini is INA pin for the motor driver. INA and INB control motor rotation for example INA = HIGH and INB = LOW mean motor rotate right then INA = LOW and INB = HIGH mean motor rotate left.

What version of the IRremote library are you using? The above code is for the older (<3.0) version of the library. See the GitHub reference for how to write code for the newer version.
