Thanks for all the effort, my (engineer) son bought me a Pico to challenge my electronically idiotic brain. I can do the code no worries, but understanding the hardware is another matter. Cheers. $0.02

This was really clear and exactly what I needed! It helped me get my head around using the pico and gave me an idea for a first project. Thank you Brad

Thank you Brad! I really appreciate the clear, precise and thorough way you explain things. I also really appreciate your brevity, it’s a really tricky skill to achieve all of these but you do so very well. I look forward to more videos and you deserve a much bigger audience and credit for what you do. Have you thought of having a Patreon page?

Amazing work Brad! Looking forward to more videos from you!

2:00 pull up resistor, or use button=Pin(22, mode=Pin.IN, pull=Pin.PULL_UP)
i prefer Pin.PULL_DOWN and have the circuit connect to 3.3v when button is pressed, it also lights up the led i have on the opposite side (going to the pico), 1 press acts on the external led and the input pin, instant visual feedback
