ESP32 Forum

Hey! I recently purchased this controller because I needed to control 8 servos, but now I'm wondering if I can use the rest of the pins to read from other kinds of sensors (in my case the would be IR sensors).

I'm working on a DEVKIT V1 with Arduino framework (because I'm more used to) but I can't come up with a solution. I know you can work with leds and such, but I would need to execute a digitalRead().
Someone has more experience?

I'm pretty sure the pins on the PCA9685 can only be used for outputs.

Just scanned the datasheet again and didn't see anything.

I have used MCP23017 before to expand GPIO. Or MCP3008 for ADC.

Hope this helps.

Thanks,

Yeah at least I can discard the possibilty. What Im going to try next is to use the v+ and gnd pin of 4pins of the controller yo power supply my sensors but connect them directly to my esp32
