    Consider the management of a digital potentiometer X9C (X9C102, X9C103, X9C503, X9C104) with the help of Arduino, as well as what areas of application this device may have. Let's use the ready module which costs less than 1 dollar.
  • ⚑️ How to connect the relay to Arduino

    The article describes such an electronic device as a relay, briefly explains the principles of its operation, and also discusses the connection of a module with a DC relay to an Arduino using the example of LED control.
  • 🌫 Air quality assessment with Arduino

    Every year with the development of technology increases the comfort of a person on Earth. Only such benefits can include not only the widespread use of smart devices but also the natural needs of man. For example, the need for clean air.
  • πŸ’» Arduino and Processing. How to control the microcontroller on the COM port. Bilateral communication

    I think it is necessary to write that I picked up the idea of the latest program from one programmer, Daniel Shiffman, who makes videos that are understandable even to children about programming in Processing (more than 140 visual tasks have been solved).
  • πŸ”Š How to connect the volume controller M62429 to Arduino

    Chip M62429 is designed to reduce the volume of sound in electrical circuits. The chip allows you to control simultaneously and independently two sound channels. The sound adjustment range is from 0 to βˆ’83 dB, i.e. the chip is able to attenuate the volume about 100,000 times.

  • 🌑 Connecting ds18b20 to Arduino (temperature sensor)

    The DS18B20 temperature sensor is a digital temperature sensor. This means that you can measure the temperature using a very simple circuit. It communicates with a common bus, which means that you can connect multiple devices and measure their values using only one Arduino digital output.
    The sensor has only three contacts, as you can see in the following figure. The DS18B20 is also available in a waterproof version.
