Incorporating Bluetooth in a project no longer requires the most advanced microcontroller or lots of code…our Bluefruit LE UART Friend and accompanying app for iOS and Android make it easy! Building upon our popular "Kaleidoscope Eyes" NeoPixel goggles project, this guide shows how Bluetooth LE can be used even with the most modest setup.
Kung Fu video games are only as good as the controllers used to interact with them. One Finger Death Punch (OFDP) for Steam on the PC is one of those games that's OK to play with a mouse or an XBox controller, but with Wii Nunchuks the fun meter is maxed out! This project shows how you can transform Wii Nunchuks into custom nunchuck controllers for the OFDP video game on a PC using a Nunchucky adapter and Pro Trinket creating what we call the iTapStick!
Digital RGB LEDs like the Neopixel are greatfor creating awesome lighting effects. But keeping them responsive to user inputs at the same time can be challenging. And what if you want to have different parts of your project animated in different ways? In this guide, we'll explore techniques to make your pixel patterns lively, flexible and responsive.
A PIC is used as a SPI Master to create a simple interface to up to 21845 NeoPixels. After being configured with the number of attached NeoPixels the Pixif continuously retrieves the RGB values via SPI and generates the NeoPixel GRB bitstream. The update rate may be throttled via a synchronization input. This approach frees the host processor to concentrate on its algorithms especially when its SPI Slave has DMA support.
