Listening to Light with a Homemade DIY Laser Communicator
Using a pet-safe laser toy and some common components along with a bit of crafty construction, Rimstar shows how to build a basic laser communicator – there are several variations of this project out there and it’s a really fun project to explore the notion of ‘transmission’ and how that operates.
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.
