So do I wire these appliances directly to the arduino board
do I have to go to relays etc.
Then How do I teach the board what I want it to do ?
I set the Arduino next to another circuit board.... the pin that tells the light to come on for five or ten minutes feed to energize the relay magnet... or not.
At the same time the PWM pin I tell to control motor speed goes to some kind of motor shield and turns it on and off so fast that it runs at 1/10th speed or whatever speed I decide I like.
Meanwhile.. I have permanently lost my Arduino board if I decide I like what I have and decide to install it in the cabinet ?
3.) I should definitely put a diode inline with the motor
4.) there's mixed reviews on whether I need a resistor in the feed from the chip to the light and motor but it can't hurt.
Now if I can find the threads that will help me burn a chip to leave with the system
