Interrupts – Part 2: Pin Change Interrupts

Part 2 of my series about interrupts deals with pin change interrupts. These are specific for AVR based Arduino and MiniEVB boards.

Interrupts – Part 1: External interrupts

Interrupts can be used to solve many challenges in microcontroller programming. However, there are also some stumbling blocks. This first part is about external interrupts.

MiniEVB Boards – an overview

LGT8F328P MiniEVB boards are available in different versions. I go into the differences and compare their power consumption.

LGT8F328P – LQFP32 Boards

The LGT8F328P is a microcontroller compatible with the ATmega328P, but cheaper and even more powerful. I show how to program LGT8F328P based boards in the Arduino environment.

Using ChatGPT and Bing for Arduino

ChatGPT is THE topic par excellence at the moment. And one reads that ChatGPT can even program. That, and how else this AI can help us with Arduino projects, is what we’ll review in this post.

ESP-NOW

With ESP-NOW you can easily send messages of up to 250 bytes between ESP32 and/or ESP8266 boards. A step-by-step introduction.

DS1302 and DS1307 RTC Real-Time Clock

I will explain the features of the DS1302 and DS1307 RTCs and show how to control them with the Rtc by Makuna library.

SRAM Management

This post is a journey into the depths of SRAM, Heap and Stack. How are variables stored there? What should be considered when using strings? Here you will find the answers.
