    Hello everyone,

    I know nothing when it comes to electronics, please be patient with me.

    I'm looking for an adjustable off delay timer that can delay multiple (2 or 3) small dc motors (cordless drill motors).

    Here is what I want to do....

    Motor A & B - both motors turn on (run) when a button is pressed.

    Motor A runs for 5 seconds then shuts off

    Motor B runs for 5 seconds at 60 rpm's then powers up to 100 rpm's after 5 seconds and runs for a total of 10 seconds then shuts off.

    I'm looking for something simple and inexpensive.


    I've seen some traffic light off delay timers on Youtube that may work, for example....

    Green light turns on = Motor A & B turn on (run for 5 seconds)

    Green light turns off = Motor A & B turn off

    Yellow light turns on = Motor B turns on (runs at a higher speed), runs for 5 seconds then shuts off

    Can you point me in the right direction on where I can purchase the above or maybe build it myself?.... again, I know nothing about electronics but I am willing to learn. The motors are 2 - 14.4 dc Dewalt drill motors.
