Low-Cost Tachometer

From drones to smart cars, from lifts to industrial robotics, all use an important device: a motor or rotating gear. For reliable, robust and efficient motor design, measurement of rotational speed is required. Therefore, an instrument called a tachometer, which has a light emitter and a photosensor is often used. The device calculates rotational speed […]

Arduino Based Fancy Lights Controller

Image
Assemble yourself a portable, four-channel multi-mode light controller using an Arduino Uno board and very few external components. The fancy lights controller described here is built around the Arduino (an Open Source single-board microcontroller) platform that can be purchased in pre-assembled hardware form. The circuit is nothing but a portable four-channel, multi-mode digital light controller, […] The post Arduino Based Fancy Lights Controller appeared first on Electronics For You . from Electronics For You https://ift.tt/2yPvlAL Electronics, Electrical

LEDs’ Light Intensity Controller Based On PWM Technique

This Light Intensity Controller Project describes how a simple circuit can be designed to control the intensity of a string of LEDs. The circuit is based on a common 555 timer IC that employs pulse width modulation (PWM) technique to control the voltage. The 555 IC is driven in an astable mode. The same circuit […] The post LEDs’ Light Intensity Controller Based On PWM Technique appeared first on Electronics For You . from Electronics For You https://ift.tt/JZwcLrt Electronics, Electrical
