The Teatime Klaxon rouses teenager with the help of a Raspberry Pi

One of James West’s sons has been known not to hear the cry of “tea time!” because of loud music playing in his bedroom. James has come up with a Raspberry Pi solution to the problem featuring a 12V LED tower with buzzer. Using some code from Pimoroni and using one of their Automation pHATs and a 12V power supply, he’s hooked it up to a Raspberry Pi Zero which monitors Twitter for a hashtag. When the hashtag is activated, the lights come on in sequence and the (quite ear-piercing) buzzer sounds. He’s wrapped the wiring inside a wooden box for safety. You can read about the project, and get the code, on his blog and see a video of the final project below:
