Hello. ADC pi is doing a lot in my current working project.

However, I also wanna control a single LED's color by the pi which is under 2 ADC pis

Is there any spare GPIO pins_which is all connected but not used by ADCpis ?

I need 3 usable GPIOs.

Hello Stephanie

The ADC Pi uses pins 1 (3.3V), 2 (5V), 3 (I2C SDA), 5 (I2C SCL) and 6 (GND) on the GPIO header. All of the other GPIO pins can be used for other purposes.
