Using the ATmega328P standalone

I’ll show you different ways to program the heart of the Arduino UNO, the ATmega328P, standalone. This saves space, costs and battery.

Logical operations and port manipulation

Portmanipulation is much faster than the classic Arduino functions. For this, logical operations are the basic tool. Both will be explained in this article.

IR remote controls

I explain how IR remote controls transmit signals and how to build a remote control yourself. I also present the IRLib2 library.

AP3216 (CJMCU 3216) ambient light and proximity sensor

The technical data and setting options of the AP3216 module (CJMCU 3216) are explained. I also present my Arduino library AP3216_WE.

HC-SR501 motion detector

The HC-SR501 PIR motion detector is described. I am going into the operating principle, the different versions and settings.

VL53L0X and VL53L1X – ToF distance sensors

The characteristics of the VL53L0X and VL53L1X are explained and the sensors are compared. Suitable libraries for controlling the sensors are introduced.
