Final day before Christmas! In the last few days, we’ve helped Santa climb the chimney, fly his sleigh, wrap gifts and find out who’s naughty or nice.
To use our last 24 LEDs, let’s wish him luck for his 24-hour delivery, and track his progress around the world.
Today we’re playing with the Twitter API and 20 LEDs, in the form of 2 10-segment bar graph displays! We are going to help Father Christmas figure out if people are being naughty or nice minute by minute.
I know Christmas songs have been playing everywhere for the last 3 months, but I reckon there hasn’t been much singing on 300 LEDs. So, to add 19 LEDs to our counter today, I’m going to make a Christmas song player with spectrum analyser.
Today we’re making a digital candle that never goes out, 7 LEDs. We’ll detect a blow, to make the LEDs flicker and have an RGB LED change colours. When this main LED turns back to its original colour, it means your Christmas wish has been granted.
