Let’s take a look at how to use the analog-to-digital converter (ADC) in an STM32 microcontroller. To make conversions happen more quickly, we can use the direct memory access (DMA) controller to pipe data directly from a peripheral (like the ADC) to memory and vice versa.

Let’s look at how to connect a simple I2C device to a STM32 Nucleo board to read temperature data using the STM32 HAL API.

A simple and robust homemade security system can be made with a handful of components and basic programming.

In this project we will combine what we learned to create a message display system where telegram messages sent to the Raspberry Pi show up on the attached LCD.

This guide will cover what can you make with an Arduino and RFID.
