Nettet6. mai 2024 · They are labeled clearly in the data sheets. It’s pretty straight forward how these work. You can connect these pins directly from the Arduino to the LED driver ICs. If the on/off pin is taken high, the driver IC turns on the LED. If it’s taken low, the IC turns off the LED. The IC goes into a low-power state when it is off. Nettet21. mar. 2024 · To do this, connect the Arduino via USB to your PC and open up the Arduino IDE or software.
