Step 7Electronics(3): Motor Speed Controller and Batteries
For the Victor 885 to know what speed to set the motors to, you have to send it +5v pulses with widths between 1ms (minimum power) and 2ms (max power). Sending it pulses with a width of 1.5ms puts the motor in neutral. The time between each pulse sent to the Victor 885 must be at least 27ms. Because you're sending it variable width pulses, this type of control is called "Pulse Width Modulation" or PWM for short.
These pulses are sent to the two Victor 885s from the PAK VIII described previously. Datasheets and other information on using the Victor 885 is included below. I also attached a datasheet of the batteries I used.
The Victor 885's LED will turn red when it's running the motors full reverse, green for full forward, and orange for neutral. The LED will blink if it's not receiving any pulse width modulation (PWM) commands.
