STM32 interface WS2812B

Last month I bought an interesting RGB LED ring from Aliexpress and finally, now, it is here. So that, I’m about to present how I interfaced an STM32 MCU to WS2812B LEDs. This demo uses also FreeRTOS and HAL libraries. I wrote a simple code to make an STM32 interface WS2812B LEDs.

Playstation controller hack with Arduino MINI and nRF24L01

This time we see a Playstation controller hack to use it wirelessly in our projects. In this article we use an Arduino MINI board wired with the Playstation’s controller circuit, an nRF24L01+ module and a small LiPo cell with an USB charger circuit based on Microchip’s MCP73831 ic.
