Here's a breakdown of what the Johnny-Five JavaScript code does: Assuming potentiometer is attached to pin "A1" The following is JavaScript code example that uses Johnny-Five library to generate PWM signal on pin 6 with varying PWM duty cycle controlled using 10KOhm potentiometer which is connected to A1 analog pin of Arduino Uno. Read analog values from the potentiometer, which will be used to Middle pin of the potentiometer to A1, and connect the other two pins toĥV and GND on the Arduino board, respectively. Then,Ĭonnect a potentiometer to pin A1 on the Arduino board. PWM signal is generated on Arduino Uno pin 6 and the PWM signal duty cycle is controlled using the 10KOhm potentiometer connected to analog pin A1.Ĭonnect your Arduino board to your computer using a USB cable.
Circuit Diagramįor the demonstration of PWM signal generation we will use the following circuit implementation. Whether you're aīeginner or an experienced developer, understanding PWM with Johnny-FiveĬan open up a whole new world of possibilities for your electronics, automation and IoT projects. Johnny-Five JavaScript library and Arduino, allowing you to control theĭuty cycle and frequency of electrical signals.

This Johnny-Five JavaScript tutorial, we will explore how to generate PWM signals using Library, PWM becomes accessible and easy to implement with Arduino. Intensity of electrical signals and is commonly used in robotics,Īutomation, and electronics projects. Pulse Width Modulation (PWM) is a powerful technique for controlling the Basic knowledge of JavaScript and electronics concepts, such as PWM and analog input/output.See the tutorials Programming Arduino with Johnny-Five in Proteus and Getting Started with Johnny-Five in Proteus for setup and installation of Node.js, Johnny-Five JavaScript library etc needed to follow this tutorial. Here we will use Proteus and Visual Studio Code IDE. A computer with Node.js and npm (Node Package Manager) installed.An Arduino board (e.g., Uno, Mega, etc.).Prepare you for more advanced projects, such as generating PWM signalsīefore diving into the tutorial, let's make sure we have everything we need:
