The project you're describing is a DIY dashboard for a Raspberry Pi, featuring an OLED display, a push button, and some LED indicators. Here's a step-by-step guide to help you build this project: ### Components Required * 1x Pin header male (2 pins) * Some hot glue * A miniature slide switch * Jumper wire * A PCB * An OLED display module * A push button switch * A push button cap * A low-current LED (3 mm) ### Steps to Build the Project 1. **Prepare the PCB**: Use hot glue to attach the pin header male to one end of the PCB. 2. **Connect the Components**: * Connect the OLED module's SCL and SDA pins to the PCB's corresponding pins using jumper wire. * Connect the push button switch's pins to the PCB's corresponding pins using jumper wire. * Connect the low-current LED's anode to the PCB's corresponding pin using jumper wire. Also, connect a resistor (1K) in series with the cathode of the LED to limit the current. 3. **Add the Miniature Slide Switch**: * Use hot glue to attach the miniature slide switch to one end of the PCB. * Connect the push button cap to the miniature slide switch's pins using jumper wire. 4. **Prepare the OLED Display Module**: Rotate the OLED display module by 180° so that it matches the orientation of the PCB. 5. **Install the Software**: * Follow this guide to install the necessary software for the OLED display: <https://learn.adafruit.com/adafruit-pioled-128x32-mini-oled-for-raspberry-pi/usage> * Edit the `SSD1306.py` file to make the necessary changes for rotating the OLED display by 180°. 6. **Run the Software**: * Copy the attached `disp.py` file to your Raspberry Pi and make it executable. * Run the script using the following command: `python disp.py` * To run the script in the background, use the following command: `nohup python disp.py &` 7. **Automate the Script at Bootup**: * Add the following line above 'exit 0' in the `/etc/rc.local` file to make the script start automatically at bootup: `python /home/pi/disp.py &` The DIY dashboard is now complete, and you can use it to display information on your Raspberry Pi.
