Transponders are designed for three different diodes. Based on the obtained results, it can be seen that when using a matching-circuit-based transponder, antenna design is more straightforward. The ...

Instead of making ESP32 directly rely on cellular networks, we connect ESP32 to the Wi-Fi network and make use of the Circuit ... from the Arduino Board library manager. Here, I am using a Macro to ...

Abstract: Mass production of widely used semiconductor digital integrated circuits (ICs) has lowered unit costs to the level of ordinary daily consumables of a few dollars. It is therefore reasonable ...

This project utilizes an Arduino Uno CH340G development board paired with a DHT11 temperature and humidity sensor to create a compact yet capable ... and the onboard LED confirms activity. Method 1 - ...

The complexity here is that we need to fix the circuit in a mobile and remote place—the helmet. So, simplifying the circuit is most important to make it compact and reliable. The circuit diagram ...

Have you ever wanted to know what is inside a digital audio mixing console? Or have you already programmed some MP3-player based on an ESP32 and the great Arduino libraries, but without the option for ...

This library supports only one DS18B20 per Arduino/ MCU pin. If you need more functions or control ... Finally this library will probably make it easier to use a DS18B20 with processing boards or IC's ...
