I used arduino to control the speed of a dc motor and also used a switch, which when pressed can reverse the direction of the motor. I had to install and program an h bridge IC to control the amount of voltage by the installed potentiometer.
I also made a temperature indicator that uses a thermistor and an led that changes color depending on the room temperature. The led fades to red if the temperature is high and blue if its low.
