Raspbery Pi Pico wifi Setup

A custom script has been created allowing you to use a Raspberry Pi Pico. You can download the screen here.

The script allows upto 8 buttons to be controlled by the pico. Arcade buttons are recommend.

The following GPIO pins are being used per button

2 3 11

There is optional setup for a single rgb pixel as status led that can in pluged in to GPIO 0

Setting Up Pico

Once you have download the custom script you will need to edit the config.json file. There are a things you need to need to change.

  1. WIFI SSID - The same network as your Android Dervice
  2. WIFI PASSWORD
  3. SERVER URL - This is the ip address of your Android Dervice. You can find the ip address if the device on the about screen of the app
  4. Button Amounts - Any amount can be set (£1-£100). Make your the format is right 2.50 = £2.50 / £2 = 2.00

Once you have made the edits to the config.json file you will now need to copy both the config.json and main.py to the pico.

{info} Most arcade buttons leds run at 12v and the Pico runs at 5v. You run the buttons at 5v but the leds in the buttons will be not as bright.

Recommendations for setting up the pico

Wiring the pico is not the easyest. I would recomend using a breakout board with screw terminals and input power. I would recomend this board from The Pi Hut that has everything you need. Pi Hut Board

Other information

When a button is pressed it will flash to show the request was made. Once the button is pressed all the leds on the buttons will turn of not allow buttons to be press for a set time (10s). This can be changed in the config.json
