Currently I have a small radio receiver (like the one found in toy RC cars) with a DC motor attached to the board. I would like to mimic the radio receiver control with an Arduino BUT I am in need of guidance in measuring the control input the board sends to the DC motor so that I can record and program this.
I have already considered using the RC input from the radio receiver rather than the DC motor but I have found that this is an integrated portion of the board so my only hope is reading the DC motor.
First attached is a simple sketch of what the toy looks like.
Second attached is my desired.
What I know is wrong with my desired sketch is that the current is too high for Arduino to handle so I planned on placing a resister there. My plan is to use the RC radio to send input to the receiver and read the inputs from the connections from the DC motor through serial using the Arduino. I am having some major issues with getting the DC motor connections to the Arduino though.
