A few times I have locked myself out of the house and needed to wait for the Wife to get home and unlock the door. So I decided to come up with a way to get inside the house if I am outside and have nothing on me. Using RFID tags hidden around outside I can put them to the reader on the door and have the door unlock. If I have my phone on me I can also unlock the door via an app I created.
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.
