MAKER：Dave Akerman/ Translated by：趣无尽 Although the basic functions of micro:bit are relatively limited compared to development boards like Raspberry Pi, its processor has enough flash memory and RAM to implement a basic tracking device. Additionally, the micro:bit comes with an accelerometer and a compass chip, making tracking easier.Below, I will introduce the method and steps … Read more
01 Introduction The touch button is a type of switch based on capacitive sensing, which can be activated by direct contact with the sensor’s metal surface by a human body or metal. 02 Principle The touch sensor module is a capacitive touch switch module based on the touch detection IC (TTP223B). When the module’s metal … Read more
01 Introduction The button, also known as a tactile switch, can create very interesting interactive projects when used with other sensors. In the image below, you can see a red button and a blue button; they only differ in color, but their usage is the same. 02 Principle When you press the button, you can … Read more
Hello everyone, this is the second lesson, where we will add an ultrasonic sensor to the previous programming car. The main function of the ultrasonic sensor is to measure distance, and using this feature, we can create very useful things. We’ll talk about the projects later; first, let’s get familiar with the sensor. Ultrasonic Sensor … Read more
01 Introduction The PWM motor is controlled by a PWM signal, allowing for precise control of rotation speed and high torque compared to a regular DC motor, although it does not achieve as high a speed. 02 Principle For an introduction to the principle of PWM, please refer to my previous article on PWM servos. … Read more
