ESP8266 & Apple HomeKit – Let’s get started

There are quite a few different types of smart home systems, also known as smart home. Each has its own advantages and disadvantages, and choosing the right system really depends on the individual user’s preferences. One such system is HomeKit from Apple. In this and subsequent materials in this series, I would like to tell you a little about how to integrate HomeKit and the well-known ESP8266 modules. I will show you how to configure such a module so that its operation can be controlled from an iPhone, MacBook or Apple Watch. In addition, we will connect to the outputs of our microcontroller various peripheral modules, the operation of which will be controlled by ESP.

Lightning sensor for Arduino

I’m sure that in the mind of anyone who has worked with Arduino boards, the idea to build your own weather station has appeared at some point. Such projects are most often based on the simplest sensors for temperature, humidity possibly pressure. Sometimes a module is also added to measure wind speed. However, practically no project is equipped with a sensor capable of detecting lightning. This is a rather strange state of affairs, given that it is very simple to run this type of module in the Arduino environment.

Barcode and QR code reader on Arduino

Practically every day we encounter bar codes of various kinds. Although we don’t usually pay attention to them, they play a very important role in today’s world – the identification of products in the store, the flow of packages in logistics centers or the proper distribution of components in production processes. Barcodes are used in each of these areas, thanks in part to their simplicity. The small size of the code can be easily scanned by an automatic scanner or an operator equipped with the appropriate equipment.
