In the last Unity3D article, some of the features in the program were mentioned. In this article, we would like to mention one interesting feature, which is the use of GPS in Unity3D, especially for beginners. Because the program has relatively simple use of GPS.
From the article Controlling a Servo 2-Wheel Robot in the ESP8266+RoboServo and the DC electric motor in VisionRobo Car: Drive Motor, we have taken the 2nd built-in robot car from the Raspberry Pi to the ESP8266 to operate via WiFi using the guidelines from the ESP-01s+Relay article. Let’s rewrite Arduino’s C/C++ with the WebServer class from the ESP8266 article to MicroPython. Thus, by the end of this article, the robot can be operated in the first example by connecting a phone or communication device. Go to 192.168.4.1 and order it to go forward, backward, turn left, turn right, or stop.
From the article Singly Linked List Data Structures, the use of the DHT11 sensor module with the STM32F103 microcontroller, and the use of the TFT display module based on the st7735s controller, the idea of this article is to take an example of using a singly linked list data structure to collect the temperature and humidity values to find the maximum, minimum, average, together with the data in the list to display in the form of a graph 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.
From reading articles on how to use board STM32L432 ADC and articles about STM32F103x connecting to ST7735S, it’s time to take STM32F103CBT6 or Blue-Pill/Black-Pill board. Let’s write a program to use ADC to display on a TFT screen. The example of the result of this article is as shown in Figure 1, which is reading from Pin PA0 that has been connected to Pin Analog signal from Board LDR in Figure 2 to Displayed on a TFT display.
This article is to convert the implementation of the regression model from the article of ESP32-C3 to NumPy on Raspberry Pi and PC and use the display as Matplotlib, as shown in Figure 1, which can be found from the previous article. The temperature and humidity from the 1-day data were obtained from parameters a and b of the regression equation and the resulting equation or model was used to determine the possible temperature values over the 1 day.
This article discusses how to create a basic animation from Blender (We used version 3.0) to create the movement of the robot arm as shown in Figure 1. The content of this article introduces Animation Tab, model preparation, and put on the skeleton and Key Frame animation as a basic guide for those interested in creating further animations.
This article introduces Unity3D, a very popular game creation program. Because there are so many facilities needed to make a game. Called quite complete, such as the manipulation of three-dimensional objects, gravity, system movement of objects, can create games on multiple platforms for example. Controlling objects requires knowledge of a programming language which can be practiced.
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.
This article discusses the use of PWM (Pulse Width Modulate) of the ESP32 microcontroller in the Arduino framework after discussing the functionality of this section in the ESP-IDF and MicroPython by connecting the board to the speaker as shown in Figure 1.
