So I have a pet project im starting up at home. I am an avid pool player and a software developer. I would like to build a small raspberry pi based device that detects when a ball goes into a pocket using a Proximity Sensor in each pocket. When a ball goes into a pocket I would like to turn on a light mounted in that pocket. So far with my investigations I have determined that I would need : 6 Proximity Sensors 6 LED Lights Then I would connect the proximity sensors to Qwiic Mux Breakout - 8 Channel device, and run a cable to the Pi. My problem is the distance on a 9ft pool table from a pocket to the center of the table (where the device will be mounted) will be roughly 5 feet and I cant seem to find QWIIC cables that long. Where can I find cables that are that long and are those even the right cables to use? Are there any other devices I might need as well? Thanks in advance! ---

Unfortunately it’s difficult for I2C (Qwiic) to work over long distances. Long meaning anything over a few feet. Sparkfun carries [[qwiic midpoint](https://www.sparkfun.com/products/18000) and [[qwiic endpoint](https://www.sparkfun.com/products/16988) boards that can be used to extend the length of the I2C bus, but those can get expensive if you need 6 of them. You might be better off using something other than Qwiic sensors since you’re needing quite a bit of cable length connecting all your sensors.]([https://www.sparkfun.com/products/16988](https://www.sparkfun.com/products/16988))]([https://www.sparkfun.com/products/18000](https://www.sparkfun.com/products/18000)) ---

What would you recommend other than Qwiic sensors? But overall i’m looking for a list of components i would need to build a prototype, an i on the right track? if not what components do i need to order to get started? i think i need a proximity sensor, cable to mux , cable to pi device. ---

GPIO expansion card/module? Example posted primarily for comedy: Note the bent pins in the several product photos. [https://www.amazon.com/Expansion-Module … B09JFM4P9J](https://www.amazon.com/Expansion-Module-Output-Adapter-Raspberry/dp/B09JFM4P9J)
