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
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
