A simple, Adafruit Trinket based hydroponics controller. This controller is for a flood and drain style hydropnics system, and uses two relays to control a pump and valve. The addition of another relay would allow for the controlling of lighting, but would require significant code revisions.
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.
