Interrupts – Part 3: Timer Interrupts

The programming of timer interrupts is hardware-specific. I show in detail how it works on the ATmega328P, ATtiny85, ESP8266 and ESP32.

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.

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.

SD cards and SD card modules

SD cards are the medium of choice for storing large amounts of data. I show how to control SD card modules with the Arduino.

Blynk – An Introduction

Blynk is an easy-to-use IoT platform that allows you to control microcontrollers remotely. This is an introduction.

Using WiFi with the ESP8266 and ESP32

I show you step by step how to network and control your ESP32 or ESP8266 boards via WLAN and how to exchange data between them.

Using IFTTT and Webhooks with the ESP8266

You want to be informed about out-of-control sensor readings on your smartphone (free of charge)? No problem with IFTTT (if this then that). I’ll show you step by step how to do this and how you track things online.

Watchdog Timer

Here you will learn: What is a watchdog timer? How to use it on Arduino (UNO) and AVR MCUs? What to consider using the watchdog timer on the ESP8266 and Arduino Pro Mini.

ESP8266 ESP-01 module

Controlling ESP-01 modules with the Arduino IDE is explained step by step. I provide example sketches with circuits. Also: AT commands.
