Hi  
I am trying to make a fruit activated sound controller that will trigger samples from a computer when the fruit is touched, like a midi keyboard. I am using this device in a theatre project where the performer triggers samples throughout the show. Please note the performer is non verbal and neuro diverse so it has to be extremely simple to trigger.

I have bought the Arduino Ono R3 Board + Adafruit MPR121

I have zero experience in this area and finding it very difficult to find information on how to achieve this with the purchased devices.

Hey @Sheshtin294796, Welcome to the forums!

This would be a cool project! We would be happy to help out. 🙂

To start with, could you clarify if you are using the stand-alone board version of the [Adafruit MPR121](https://core-electronics.com.au/adafruit-12-key-capacitive-touch-sensor-breakout-mpr121.html?gad_source=1&gad_campaignid=17417005429&gbraid=0AAAAADlEpP4vAIBuNhBIAQA_4vQ0CdeVS&gclid=Cj0KCQjw9O_BBhCUARIsAHQMjS6afihERj29OGAaUcGrVsSm1cY9-qSB16F5TgdoEWoBZzgtjHqxMo4aAkvmEALw_wcB):

Hey @Sheshtin294796

The set up for both will be similar and you can follow along with [Adafruit MPR121 12-Key Capacitive Touch Sensor Breakout Tutorial](https://learn.adafruit.com/adafruit-mpr121-12-key-capacitive-touch-sensor-breakout-tutorial/overview) omitting the parts in the guide about wiring it up to the arduino as you will instead put it directly on top of the Arduino.
