Arduino provides a very powerful library – the `Servo` library, specifically designed for controlling servo motors. This library can control various types of servo motors and efficiently utilize timer resources, allowing a single timer to control multiple servo motors. Below we will detail the functions, usage, and some precautions of the `Servo` library. 1. Introduction … Read more
The control of the servo generally requires a 20ms timing pulse, where the high level part of this pulse is typically within the range of 0.5ms to 2.5ms for angle control. For a 180-degree servo, the corresponding control relationship is as follows:0.5ms————–0 degrees;1.0ms————45 degrees;1.5ms————90 degrees;2.0ms———–135 degrees;2.5ms———–180 degrees;Please see the illustrative description below: The operating voltage … Read more
The smart dustbin using Arduino and ultrasonic sensor is an innovative IoT project that simplifies waste management. First, it uses an ultrasonic sensor to detect nearby objects. Then, a servo motor automatically opens and closes the lid. Therefore, this contactless design promotes better hygiene and perfectly fits with the growing trend of modern IoT solutions. … Read more
Control the servo motor via web using Arduino and ESP8266 module. In this article, we will implement control of the servo motor through a web interface. The webpage will be created using ESP8266 module, and the servo motor will move in response to the slider on the webpage. Connect the ESP8266 to the Arduino UNO … Read more
Today, we will introduce how to build a wireless network consisting of multiple NRF24L01 transceiver modules with Arduino. In this project, we built a network consisting of 5 nodes, where each node can communicate with any other node in the network, and they can act as both transmitters and receivers. In fact, this project sets … Read more
In this article, we will learn about the working principle of servo motors and how to control them using the Arduino development board and the PWM driver PCA9685. There are many types of servo motors, and their main feature is the ability to precisely control the position of the shaft. A servo motor is a … Read more
Controlling one or two servo motors with an Arduino development board is very easy, but what if we want to control multiple servo motors? In this article, we will introduce how to control multiple servo motors using an Arduino development board. Connecting multiple servo motors to the Arduino development board seems easy, but if we … Read more
