In this tutorial, we will learn to use STM32 Nucleo timer in PWM mode to generate PWM signals and how to configure them to generate signals with different duty cycle and frequency. We will use an LED dimmer example to demonstrate how to setup the timer in PWM mode using STM32Cube IDE and HAL libraries … Read more
In this tutorial, we will learn how to build an android app with a slider that will enable us to control the brightness of an LED connected with Arduino. The slider will be moved to set the slider value. In response, this slider value will set the duty cycle of the PWM signal generated by … Read more
In this comprehensive user guide, we will learn to interface a rotary encoder module with Arduino. We will discuss about the working of rotary encoders, its pinout, and its connection with Arduino. With the help of two sketches, we will show you two different ways to read the rotary encoders. They will focus on how … Read more
In this ESP32 web server project, we will learn how to build an ESP32 PWM WebSocket web server that will control the brightness of multiple LEDs connected to the ESP32 GPIO pins. This will be achieved through multiple HTML sliders that we will add to the web server page. The sliders will be moved to … Read more
