In the lesson we will learn how to connect a DS18B20 temperature sensor to the Arduino board, how to control it using the OneWire library. We will develop an accurate thermometer.
The lesson describes the use of silicon temperature sensors in the Arduino system. The working project of the thermometer is given. Along the way, the issue of measuring resistance in the Arduino system is considered.
Lesson on connecting integral temperature sensors with analog output to the Arduino controller. The working draft of the thermometer is given, it is told about the software processing of information from thermal sensors.
In the lesson we will talk about character LCD displays, about connecting them to the Arduino board and controlling them using the LiquidCrystal library.
We will consider the Arduino functions for working with time. Develop a sports stopwatch based on the Arduino board.
The lesson discusses the method of connecting a LED seven-segment display and a matrix of buttons to the Arduino board. A library for working with such a structure is presented.
In the lesson we will connect a seven-segment LED display to the Arduino board and learn how to control it using the Led4Digits.h library.
In the lesson we will learn about the diagrams for connecting seven-segment LED displays to microcontrollers, about how to control them.
Let's learn how to connect a matrix of buttons to the Arduino board and use the standard tone() function to generate sound.
In the lesson we will develop a real, workable project of the security alarm system. You can easily adapt the device to your tasks and conditions.
