I have a webcam in my conservatory that is connected to a Raspberry Pi. You can see it at the top right of the picture with the red LED just under the air-conditioning unit. When it rains the sound of the raindrops on the roof is very loud and I thought I could use the microphone in the webcam to estimate the amount of rain. The Raspberry Pi also controls my irrigation system, and I wanted to reduce the water consumption by stopping the irrigation when it has rained.

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.
