I have been impressed by how Bitcoin Blockchain technology works, and how you can easily send/receive funds. And since I am a maker, so I asked myself “What about easily connecting hardware projects to such network making these hardware accepts bitcoins?”. Then I started by implementing the first Arduino Bitcoin library called Koyn.
Rapidly wrapping up, Koyn is an Arduino library that helps Arduino makers to build their hardware projects and connect them to the Bitcoin network (currently supporting test network) and accept bitcoins, making it easy for the users to take hardware actions whenever they spend/receive bitcoins.
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.
