Putting together therapeutic device using vibrating motors and heating element. Motors are rated at 3V and 70mA each, and the heating element at 5V and 700mA which I understand is too much for the Arduino Uno. I also want to limit the heating element to 40 degrees Celsius
I am led to believe that I will need a steady state relay or even a PID controller but I am unsure of the layout and coding to achieve this.
