Version 2.03 for our dual output PWM board. Example program uses first driver as the main PWM for driving LED string. The 2 onboard buttons control duty cycle of first MOSFET transistor from 5 to 100% A trigger pin on IO connector triggers 90 second count down timer for second MOSFET Rev 2.03 adds auto shut off for MOSFET 1 Both values adjustable in setup loop
On / Off button - available through connector short press GRADUAL ON / OFF double press instant ON / OFF
up button
short press gradual on till last level then step up long press continous level up till max double press instant On till last level or min if last was 0
down
short press if on redure by step or off if at last step long press continous step down till off double press auto gradual off
