Bitcoin and blockchain technology opened a whole lot of opportunities for paying for goods and services but the catch was that it wasn’t fully automated because it lacked easy hardware integration support. However, it got easier with the release of the Koyn library. In short, the Koyn library allows your hardware like Arduino compatible boards to receive and send Bitcoin payments.
One application model for Bitcoin that interests me is pay per service, and one of many applications I decided to get my hands dirty on is renting electricity. So, I started building an electrical outlet that is powered by Bitcoin.
This project works on HIGH AC voltage which is quite dangerous. Your safety is your own responsibility, including proper use of equipment and safety gear, and determining whether you have adequate skill and experience. You must accept that you and you alone are responsible for your safety and the safety of others if you choose to build this project.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
