Plants liven up any space by adding a sense of airiness and life. That is – of course – when you don’t forget to water them, and they shrivel up and die. I am very bad at remembering to water plants. That is why I built this self-watering plant to do it for me. Using a soil sensor, and an Arduino-controlled water pump, I have created a system that will never forget to do it. Instead of remembering to water my plants when the soil goes dry, I only have to remember to once and a while refill the water reservoir. In this way, I have decreased my obligation to these plants and put it off to a much later date. Perhaps further iterations of this device can be connected to a rain barrel so that I won’t even have to worry about refilling my reservoir, and the entire system can be fully automated.
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.

Care to share how you built it? I’m specifically interested in the pump.
@Chris did you follow the link? Randy shows every step in great detail.
Awesome. (Though I do agree with Chris. Sometimes, it’s hard to locate the link, though I now know where to look at it because I’ve been following the blog for a while… Perhaps a “read more” link after the text?)
Using an arduino for that makes Bob Pease’s ghost sad. Where’s the 555 contest when you need it.
@as – please make a project like this using 555 timers and show everyone what’s possible, we’d love to post it up here.
