Lesson 16. Improving the reliability of programs for Arduino. Watchdog timer.
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.
Lesson 15. Pointers in C++ for Arduino. Conversion of different data types to bytes.
In the lesson we learn what pointers are, and how they allow us to optimize the program code, learn how to convert complex data types (int, long, float ...) into a sequence of bytes.
Lesson 14. EEPROM in Arduino. Data integrity control.
The lesson describes how to work with the internal EEPROM of the Arduino board, about data integrity monitoring during storage and transmission.
Lesson 13. Analog inputs of the Arduino board. Reading analog signals. Measurement of the average value of the signal.
Lesson 12. Serial port UART in Arduino. Serial library. Debugging programs on Arduino.
The lesson describes the Arduino board UART serial interface, the library for working with it, and the use of the UART port for debugging programs.
Lesson 11. Program timers in Arduino. Cycles with different period times from one timer.
Let's learn how to create program timers in parallel processes. Let's develop a training program for security alarm.
Lesson 10. Timer interrupt in Arduino. MsTimer2 library. Parallel processes.
We learn how to work with timer interrupts. We write a simple program with parallel processes.
Lesson 9. Creating a library for Arduino.
Lesson 8. Digital filtering of signals in Arduino programs.
We learn about another way of processing the button's signal to filter out noise and eliminate contacts bounce.
