Make a coaster that lights up when your cup or glass is placed on it. via instructables
For a project at school , we had to design a light fixture that uses pleated plexiglass.
In the beginning it was thought to make a coaster that lights up when the glass is empty or nearly empty, so can be used in a restaurant, cafe, … the coaster to see if anyone wants to order a drink.
For this, however, would require a non- gate in order to detect this. This I have unfortunately not enough knowledge to do this . Therefore, it was chosen to highlight the luminaire as a glass is placed on the coaster .
In this Instuctable I show how I made the coaster .
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.
