✔This project is brought to you by Altium. I just love controlling things wirelessly over long distances using the internet is the communication medium. And over a short distance using Bluetooth or other RF transceiver modules. You might have watched my projects on SB 32 and SPA 2, double 6.
✔ESP32 and SPA 2, double 6, 55 modules are 3.3 volt compatible controller boards. and I have been using these controller boards and IoT based projects for controlling electrical devices from anywhere in the world using different IoT platforms, including the blink application. Things speak, UV dots IFtt, Google Assistant, Firebase, and Telegram, etcetera. If you’re using any of these IoT platforms or any other IoT platform, then you can only control the devices when the controller port is connected with the Wi Fi. Why use Wi Fi when we are inside a room?
✔We can use a Bluetooth supported Android application to control different electrical loads, or we can use an IR remote controller. I have already explained how to control different electrical loads wirelessly using the ESP32 built in Bluetooth module and an Android application. So if you want to control your home appliances using Bluetooth and Internet application, then go ahead and watch my previous project. I will provide a link in the description. Today, I’m going to use the same ASP 32 development board with the small size ir remote control and ir sensor for controlling these 4 different colored 220 volt AC light bulbs.
✔For demonstration purposes, I’m using only 4 lights. If you want, you can increase or decrease the number of lights or you can use some other electrical loads. Anyways, before connecting all the four lights with the relays, first I checked all the four lights. And by the way, Be very careful while working with 220 volt AC because it can be really dangerous. After checking all the four lights, I disconnected the 220 volt AC supply, and I started connecting all the four lights with the relays Don’t worry, I will explain all the connections with the help of a circuit diagram.

Da hat der Autor wohl die Tonspur seiner Videos in eine schlechte Diktier-Software gefüttert. Das Buch strotzt nur so vor (teilweise Sinn-entstellenden) Schreibfehlern. Das kann man ja teilweise hier in den Text-Auszügen schon sehen: aus dem ESP32 wird “SB 32”, aus dem ESP8266 wird “SPA 2, double 6”, as und is werden wahllos vertauscht, “UV dots” soll wohl UbiDots sein, und so weiter. Im Kapitel über Google Spreadsheets ist die Rede von “this sheet” und “I will simply write 60 over here”. Leider sehen wir mangels Video nicht, was gemeint ist. Das zieht sich so durch. Es gibt so gut wie keine Code-Beispiele und keinerlei weiterführende Links. Zusammengefasst: sprachlich eine Frechheit, insgesamt unbrauchbar. Dieses Buch geht zurück.
