IR Remote Control Calculator Using Raspberry Pi Pico 2

To build a remote-controlled calculator using a Raspberry Pi Pico, an OLED display, and an IR remote control, follow these steps:

Step 1: Set Up the Raspberry Pi Pico 2

1. Install CircuitPython:

   • Download CircuitPython for Raspberry Pi Pico from the CircuitPython downloads page.
   • Put your Pico in bootloader mode by holding down the BOOTSEL button while plugging it into your computer.
   • Drag the downloaded .uf2 file onto the Pico. It will reboot into CircuitPython mode.

2. Prepare the Libraries:

   • Download the CircuitPython library bundle from Adafruit's GitHub page.
   • Extract the bundle and copy the following libraries to the lib folder on your Pico:
     • adafruit_displayio_ssd1306
     • adafruit_display_text
     • adafruit_irremote

Step 2: Wire the Components

1. OLED Display:

   • Connect the OLED display to the Pico as follows:
     • SCL to GP5
     • SDA to GP4
     • VCC to 3.3V
     • GND to GND

1. IR Receiver:

   • Connect the IR receiver module as follows:
     • VCC to 3.3V
     • GND to GND
     • OUT to GP3

Step 3: Write the Code

- connect the usb cable to computer

- dont forget to decode the ir signal

Step 4: Test and Debug

• Upload the code to your Pico and connect it to power.
• Test the remote control to ensure that all buttons correspond correctly to the intended calculator functions.
• Debug any issues by checking connections, ensuring correct codes for each button, and verifying the display output.

Step 5: Optimize the Code

• Fine-tune the display centering for different lengths of text.
• Refine the operation handling to support more complex calculations if needed.

Final Testing

• Ensure that each button on your remote triggers the correct action on the calculator.
• Test the calculator functionality with different inputs and operations.
