This project turns a toy hammer into a magic wand that produces different sound and light effects depending on the spell cast based on simple gesture recognition. The amount of components in this project combined with the small room requites a bit of cramfu to get all the parts to fit. The compact nature of this project and the number of components means it's a best for a somewhat experienced maker.
Pocket-sized fun is the name of this game, with the Joy Bonnet - our most fun Bonnet ever (no we didn't even think that was possible, either!) This Bonnet fits perfectly on top of your Raspberry Pi Zero (any kind) and gives you adorable hand-held arcade controls. Once you install our script onto your Pi, the controls will act like a keyboard, for easy use with any emulator or media player.
Arduino is a great starting point for electronics, and with a motor shield it can also be a nice tidy platform for robotics and mechatronics. Here is a design for a full-featured motor shield that will be able to power many simple to medium-complexity projects. Build the kit, and learn how to use it with these detailed instructions.
If walls could talk. If fridges could email. If toasters could tweet. If garbage cans could blog. If sinks could post stories. If stoves could code. The Internet of Things can be in all the things. Adafruit, Digikey, and Nimbus the Friendly Cloud Entity are here to help you learn how to connect everything you need and nothing you don't.
Interpretting datasheets is fraught with peril in the best of circumstances. Even chips from the same vendor can use varying terminology and units, often in an attempt to hide short-comings in individual devices. Trying to compare chips across vendors adds another layer of complication. We'll help you decipher the key terms around gyroscopes in this learning guide.
With some development boards, low power usage is an afterthought. Especially when price and usability is the main selling point. So what should you do when its time to turn around and make that project of yours run on a battery or solar? Sure you could try to hot-air that regulator off, or you could jerry-rig a relay. Or, use a 555? Ugh, the options aren't that great.
