This article is about programming C/C++ language with Arduino Nano, Arduino Uno,LGT8F328P [NANO F328P-C], ET-BASE AVR EASY32U4 or other boards and platforms that use C language to store temperature/humidity data from the DHT11 sensor (Figure 1) with a dual linked list data structure. The basics of memory reservation, access, memory deallocation can be read in the previous article (Singly Linked List).
This article is about programming C/C++ language with Arduino Nano, Arduino Uno,LGT8F328P [NANO F328P-C] and ET-BASE AVR EASY32U4 (Figure 1) or other boards and platforms using C language for learning to code another type of data structure management program that has different storage and management methods, called BST or Binary Search Tree, as in Figure 2, which is a structure that can be applied to collecting data with attributes in which the data on the left node is less than current node and the right node is greater than current node or the opposite, the left node is greater and the right noe is less. Thus, searching for data in the event that the tree is balanced both left and right on the BST structure saves time or number of searches per round by half of available data, for example, there are 100 data sets in the first round, if the current node is not what you’re looking for it, the choice left is to find from the left or right node. This selection causes the data of the other side to be ignored or cut it in half approximately but if the Binary Search Tree is unbalanced, the search speed will not be much different from the Sequential Search.
This article describes Queue Data Structures previously written in the Python Queue Data Structure article and is frequently used with the MicroPython example, but this article is written in C via Arduino IDE to use with microcontroller board LGT8F328P, SAM-D21, ESP8266, ESP32 and ESP32-S2 as shown in Figure 1 by using an example of the array structure and a single link list as a queued data structure. This article is probably the last article on JarutEx.
This article describes a stack data structure to write programs in C on various platforms using a single linked list data structure as a stack data store with examples of the array as storage and test the operation with the microcontroller board LGT8F328P, SAM-D21, ESP8266, ESP32 and ESP32-S2 as shown in Figures 1 and 2. In case of wanting to use with other platforms, you can still modify the code for use such as the same.
This article describes the use of the ST7735s module with the ESP32-S2 microcontroller via the TFT_eSPI library. We have previously discussed its implementation with the ESP32 and STM32F103C microcontrollers, and the chosen TFT module as REDTAB80x160 (added code for GREENTAB80x160 at the end of the article), but you can adjust the settings to other modules, see the User_Setup.h file of the TFT_eSPI library as shown in Figure 1.
This article is about programming C/C++ with Arduino Nano, Arduino Uno, LGT8F328P or other boards with C-capable platforms. A pointer is used to point to a memory address and memory management methods, including memory reservation memory access and deactivating the use of memory to create a method for storing data in a Single Linked List along with an example program used to store a list of temperature and humidity values from the DHT11 module as shown in Figure 1.

This article applies the ESP32 microcontroller’s DAC and MicroPython to open WAV files, which are audio recording files and exported to the DAC connected to the speakers as shown in Figure 1. The used file is an uncompressed 8-bit mono PCM audio file. And the sample program supports a sampling rate at about 50KHz or at 44100 level.
