Have an awesome project in mind using some LEDs. In that project I will be using some LED Fading Effect and few LED Chaser Circuits. But before jumping onto that, I thought I should create a short tutorial and show you guys how to fade a LED with or without an Arduino automatically or manually […]

The purpose of this Instructable is to build a portable device that can measure the speed of sound in refrigerant gases and use this data to identify them. The speed of sound in an ideal gas is related to two characteristics of the gaseous substance, its molecular mass (kg/mol) and its adiabatic constant (heat capacity ratio), or

Step 1: Ingredients: Electronics Arduino Breadboard LCD* 2x 50k pots 150 ohm resistor Jumper wires, and tons of them! If you do not want to use a LCD then you will have to use serial monitor. Wherever you see lcd.print just change it to Serial.print. Instead of lcd.begin change it to Serial.begin(9600);. Step 2: The

Rafael Fuentes, Carmen María Fuentes and Carmen Pérez decided to create this project that was submitted to ‘Creative Electronics’, a Beng Electronics Engineering module at University of Málaga, School of Telecommunications. The project consists of making an eggbot using an Arduino Uno development board. This project was done for being a good introduction to CNC machines
In this instructables you will learn how to wire 4 LED’S and make them flash 10 times. This is a great Starter project!! what you will need… 1: arduino (I am using an Duemilanove) 1: breadboard 4: LED’s 10-15: jumper wires 3: resistors Step 1: Adding the LED’s and Resistors1 First put the LED’s on

Demonstrates the use of analog output (Pulse Width Modulation (PWM)) to fade an LED. PWM is a technique for getting an analog-like behavior from a digital output by switching it off and on very fast. Circuit An LED connected to digital output pin 9 through a 220-ohm resistor. Schematic image developed using Fritzing. For more circuit

This project was submitted to ‘Creative Electronics’, a Beng Electronics Engineering module at University of Málaga, School of Telecommunications (https://www.uma.es/etsi-de-telecomunicacion/). It’s a modification based on sound level meters that are already marketed for use in classes to measure ambient noise. The project is developed in Arduino. It consists of a LED screen in which emoji

Once upon a time, 2 girls greatly enjoyed walking in the rain with umbrellas. They decided the enjoyment of this experience could be maximized by building their own pressure-activated web of LEDs to install under their umbrella. Thus, with the help of an Arduino, some 4051 multiplexers, a lot of wire and a lot of
