I wrote a quick sketch to read the current time from the Maxim DS3231 on the Chronodot, and to cycle the display through hours, minutes, and seconds. The first digit of the hours fades in from black to red, then the second digit fades in as green and out to black. The first digit of the minutes fades in from black to green, then the second digit fades in as blue and out to black. And finally, the first digit of the seconds fades in from black to blue, and then the second digit fades in as red and out to black.
The display is nice and bright bright. I had to shoot this video through several pieces of tinted acrylic to stop my iPhone from adjusting the exposure. I didn’t realize this until I uploaded the video, but there is a bug in my code when accessing the DS3231 registers right as the minutes increment. But you get the idea, right?
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.
