Hi,

I need to detect pins that have fallen in a bowling alley so I have 10 sensors. Which ESP32 should I use (esp32-30 pins or esp32-38 pins) ?

What pins should i use?

Regards
Thierry

What type of sensors are we talking about? What signal do they give out?

I'm not sure yet which sensors to use. I need 1 per pin (these are small pins connected by a string) and 1 sensor to detect a reset signal.

Then I suggest you figure that out first. Sensors are very different: some output an analog value, some can be daisy-chained using SPI, some are SPI but need individual CS lines, some can have a few at the same time on an I2C network...
