This Arduino project demonstrates how to use a potentiometer as an analog input to control the brightness of an LED using PWM (Pulse Width Modulation). The analog input is read from pin A0, scaled to ...

In this tutorial, I will show you how to control the brightness of an LED or the speed of a DC fan using an Arduino board, a BC547 transistor, and a potentiometer. Follow along for a step-by-step ...

今回は前回のLED点灯を押しボタンスイッチで制御します。押しボタンスイッチは、ボタンを押すことであらかじめ決まっているピン同士が接続されます。今回は押しボタンスイッチを押すことで、GND（0V）に接続されたピンとマイコンボードと繋がっている ...

Hi everyone, I recently completed a fun project using the Arduino Uno, a potentiometer, and a servo motor. The concept is simple yet fascinating: the potentiometer controls the angle of the servo ...

Call it synchronicity, or manually setting a 16-bit number in an Arduino, or how to turn an OLED into a rotary dial... What am I talking about? Well, I was just compiling the blogs pages for the next ...

In this DIY article, I will be explaining how to interface X9C10X series of Digital Potentiometer with any microcontroller, for ease of explanation I will be using any of the board from Arduino eco ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

From a simple electronic toothbrush to complicated robotics systems, DC motors are present everywhere. In most of our previous Arduino projects, we have used these DC motors as actuators and ...
