Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Sorry, the comment form is closed at this time.
Back when I used to fly small planes, one of the aviation magazines had a monthly article: “I learned about flying from that” – all about mistakes made while flying (survived!) that taught important lessons.
I recently dusted off an amateur radio project that I put on the shelf 2 years ago because it was not working out as I’d planned. Oh, the mistakes –
BS170P in an ‘E-Line package’ that is not *quite* a BS170 – pins were flipped (D-S-G became G-S-D … no worky!).
No ground to one of the boards – schematic said it was inbound on a cable, but PCB had left it off.
No ground on that PCB carried down to an LM386 speaker output that I’d built, causing all havoc there – Horrible BUZZZZZ.
That radio works now! Patience (sometimes the patience of Job) and re-reading and double-, and triple-checking, and trying alternatives… that’s what works.
