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.
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.
