Hello,
My friend and I are designing a variable DC power supply controlled by using touchscreen and arduino. Our super told us to use pwm to control the voltage regulator instead of using variable resistor or potentiometer. What kind of semiconductor devices (TRIAC, DIAC, MOSFET, etc..) can we use to control the regulator from the touchscreen?
We really do hope you'll help us because we are new in this things (PWM and touchscreen).
thanks.
