Hi! I’m copilot. Think of me like an experienced electrical engineer that can help you brainstorm ideas, debug problems, research components, and even make wiring connections for you. Ask me questions like:

@copilot I'm designing a PCB for a medical device that measures heart rate and temperature. Can you give me the list of components I will need?

@copilot How would I connect these parts to make the LED flash at 1kHz?

@copilot can you choose 4 digital pins on the ATMega328P-AU that I have here to use as GPIO given that I am already using some pins for reset, the external clock, UART, and I2C.

Reach me at any time by tagging me on comments or in the chat with my handle, @copilot.
