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.
The article presents a simple security alarm project, a description of the operation, resident software (firmware). The device is not difficult to assemble with your own hands. All the information necessary for this is in the article.
In this lesson we will talk about ways to increase the reliability of programs for Arduino, learn how to use the watchdog timer in the Arduino system.
