Building your own garage door remote is an easy and moderately priced first project for any one interested in the world of hackers and makers. Personally this modification is the most useful of the projects that I have attempted. Over the last few years it has been updated and improved so that the radio remote that came with the door is almost never used. Plus, with the added sensors, I can check the closed status of the door and open or close it from anywhere there is internet access.
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.
