After finishing my first entry for this competition where I almost missed the deadline.. I realised I had another whole month as the deadline was pushed back. So what better way to continue my learning than to build something for the other category using the Alexa Voice Service!
Trying to wrack my brain for ideas.. I was inspired by the header image and decided to build my own time machine!
OK so I’m not Doc and I didn’t require any flux capacitors, but a soldering iron and 7 panel displays were involved. I decided to make an Alexa enabled alarm clock!

Adafruit 1.2″ 4-Digit 7-Segment Display w/I2C Backpack – Yellow: What’s better than a single LED? Lots of LEDs! A fun way to make a numeric display is to use a 4-digit 7-segment display. LED matrices like these are ‘multiplexed’ – so to control all the seven-segment LEDs you need 14 pins. That’s a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you but there’s a lot of wiring to set up and they take up a ton of space. Here at Adafruit we feel your pain! After all, wouldn’t it be awesome if you could control a matrix without tons of wiring? That’s where these adorable LED matrix backpacks come in. We have them for a variety of 8×8 and 7-segment displays. They work perfectly with the displays we stock in the Adafruit shop and make adding a bright display trivial. (read more)
