LED Level indicator - 8 LEDs common anode red

Product information:

LED Level Indicator Board with 8 individually controllable red LEDs. Useful for visualizing outputs or creating a level indicator.

Simply connect all the LED pins to your Arduino, Raspberry Pi, ESP or other microcontroller and turn them on and off.

This is the common anode version, meaning all the positive terminals of the LEDs are connected together. This way, you can get the power for the LEDs from somewhere other than your microcontroller.

So you direct them by making the pin low.

Voltage: 3,3V - 5V
