I don’t work with ATTINY85 development boards often, but when I do I always make the mistake of killing the Zener diode between the USB power and ground (by shorting it). Mostly because when I use them on breadboards, I forget that the power pins are all in a row. Oops. This is a board from one of my projects, where I decided to double down on the sketchiness by simply brushing away the charred remains of the diode and using a jumper. Luckily, this board will never be used in a USB port again so it’s unlike to kill a USB port anytime soon but I’ve made a habit of reminding myself not to do this! #showandtell #sparky

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.
