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.
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.
