Hey all you lovely people!
I am working on a quite interesting project. I own a portable wand shop that travels to conventions and parties. It’s inspired by Harry Potter. I made my shop “interactive” meaning that when customers come into the shop, they “test” out several wands until the right wand chooses them. To achieve this, I’ve created a control box with an MP3 module that creates the illusion of magical effects.
The control box has a 18 channel Pololu maestro, a Robertsonics MP3 module, 4 buttons, and 10 leads to control servos and other hardware.
Here’s what each of the 4 buttons is intended to perform.
- Plays an MP3 of the wand “failing” to fire.
- Plays an MP3 of thunder and lightning, activates strobe lights, then turns off after 8 seconds.
- Plays an MP3 of wand firing, richocheting and causing havoc, activates 4 servos which move, shakes, and “breaks” props. Props “repair” after 16 seconds.
- Plays an MP3 of the wand “choosing” customer, servo lifts sign reading “Chosen One” then goes back down.
What I am seeking assistance is on how to turn on a plug connected to a strobe light (Button 2). I essentially need to build a powercord/light switch that can be controlled by my Pololu maestro. I’ve read that it can be done with a relay switch. Is there a compatible relay provided by Pololu that can achieve this? I’ve been looking at the 5v relay, but I’m concerned that it would not be able to handle power coming from a wall plug.
ALSO, very importantly, what would be the code to activate and de-activate the relay?
