Do you know a kid that likes to pretend that they are a wizard or a fairy princess? How would you like to give them a toy wand that can turn on/off electronic devices like magic? You may even be able to teach them a thing or two about electronics in the process.
In this project, I show you how you can make magnetic switches that can be used to activate a circuit just like a regular momentary switch. This lets you add magnets and magnet sensitive switches to toys so that they can interact with each other
