Drive the neighbours mad with 8 static leds, that when they move their head, or drive past, delivers a festive message!
Ingredients.
1 Arduino board (I used a 3.3V 8MHz mini, but anything will do)
8 LED's (if using a 3.3V board, make sure you have enough voltage to light the LEDs!)
8 current limiting resistors
Connect each LED to pins 0-7 (noting 0 and 1 are RX and TX) via a current limiting resistor, and ground.
Load the code from https://github.com/andydoswell/christmas-POV
and enjoy the festive season!
And here's Stuart W's version!
Super idea!
ReplyDeleteBuilt it. The LEDs are blinking.
ReplyDeleteHow can I correctly move the circuit to read the text.
Me and my pupils were waving like windmills but it was nearly impossible to read the letters...
Shake your head! Alter the delay microseconds to suit the processor and clock speed as they all seem to vary a bit!
DeleteWe built it and LEDs are flashing.
ReplyDeleteHow can we make the letters visible?
Just waving hands doesn't work for me and my students.
Do we need a camera and long time exposure?

DeleteHey Andy,
ReplyDeleteThanks for sharing these amazing hacks for Christmas decoration, i missed these amazing tips to decorate using visible LEDs but i will surely use these on new year.
