My daughter is having her first child, my first grandchild, and I built a framed mirror with some graphics and her name etched from the backside, so light from the back of the mirror will travel through the etched areas. I put rgb leds inside the frame to light it up using neo pixels. This little program, maybe not the most efficient way of doing it, works quite well using twitter to change the color of the backlights. So any one of her friends can tweet a hashtag and change the color if they know the hash tag.
Since I haven’t figured out how twitter can pass values along with the hashtag, the color has to be part of the hashtag, no big deal… something like this… #kidsnamepink, or #kidsnamewhite, etc. So then I just check the hashtag and see if a predefined color name is there and change the color accordingly. It seems that you can add as many triggers as you like to one thingspeak channel, so I have added a few. I check the channel every 5 seconds to see if the color is different.
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.
