California-based 13-year old Nicholas Harris (aka ScarabCoder) has created a great electronics project (okay, it was some time ago but I only just spotted it!). He’s taken some LEDs and buttons to create a ‘keypad’ of sorts and then written some Python code which detects the button presses and changes the state of the LEDs depending on whether the correct ‘code’ is entered. Great to see this sort of thing from a youngster. Watch the video below, leave him a comment on YouTube or read his blog! I previously featured Nicholas when he contributed to the Minecraft universe via Martin O’Hanlon’s website.
