It’s almost Halloween and the guys want to do something Halloweeny! The shiny LEDs and the dulcet tones of the piezo buzzer have inspired Luke and Louise. We’ve spawned a mini project in the form of a light and sound show for trick or treat. The idea is simple. Press “Treat” for a nice light and sound show, “Trick” for the nasty, evil one. Should be straight forward to setup using a few outputs on the Arduino and two switches. Luke’s on the search for a (plastic) skull, and I’ve got my Arduino fired up and working to help the guys pull together a sketch.

On the kettle experiment front, they’ve done well and have a working servo switch that is activated by light. The only slight issue is the servo control sketch doesn’t perform a momentary action, it just moves a set angle with the standard sketch. I’m tasked with converting the sketch to allow the servo to move a preset angle and return to the original start position. Luke’s going to drop off a servo so I can have a play.

Whilst this is going on thoughts have turned to the next project. More on that next time. Happy Halloween!
