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.

HC-12 Radio Module

The HC-12 radio module is easy to handle and has a long range. I’ll show you how it works, how you make settings, and how you use it legally compliant (in Germany).

Remote shutter for smartphones – Part 2

In this second part about remote shutters, I’ll show you how to trigger your smartphone camera with BT modules like the HC-05 or HC-06.

Remote shutter for smartphones

I show you how to hack a remote shutter for your smartphone to control it via an Arduino. Moreover: problem-solving for long-term operation.

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.

Arduino IoT Cloud – Part 2: Arduino SIM and Sigfox

Many projects are implemented in places where there is no Wi-Fi. Connectivity via the Arduino SIM card or Sigfox are possible alternatives. This article is a guide and a testimonial.

Arduino IoT Cloud – Part 1: Introduction

With the Arduino IoT Cloud, projects can be easily controlled over the Internet. I will show you step-by-step how this works, but also go into limitations.

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.

ESP-01 port expansion

Port expansion for the ESP-01 using the MCP23017, PCF8574 and the 74HC595 shift register are explained in this post. With circuits and sample sketches.

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.
