LM324

These devices consist of four independent high-gain frequency-compensated operational amplifiers that are designed specifically to operate from a single supply or split supply over a wide range of voltages.

Building LM35 4 Channel Amplifier Board

“In this article,I will explain how to assemble the 4 channel LM35 amplifer board we made. This instructable requires that the user is comfortable operating and using a soldering iron. Reading resistor Colour codes or using a multimeter to …

Parts-Bin Oscilloscope

“Introduction The story is simple. I decided my electronics learning journey had reached a point where an oscilloscope would be a useful tool to have. However, I’m not sure how long this electronics hobby will last and so I …

Project  RF Listener

RF Listener

“So what is this thing? Basically it’s a handheld device that allows you to “hear” RF sources. Regular rf receivers single out a particular frequency and decode it into some type of information. This device on the other hand …

Arduino Negative Voltmeter

“3-channel voltmeter with the ability to measure both negative & positive voltages on the same circuit or 3 different circuits simultaneously Stuck with only one multimeter/voltmeter ? But, sometimes you need to check 2 or 3 voltages as the same time …

Simple Dry Electrode EMG for Arduino

“Electromyography is a technique used for recording the electrical activity of a muscle. In order for a muscle to move, it must receive an electrical signal from the brain via a motor neuron, with the frequency of nerve impulses controlling …

Wink Detector

“This instructable explains how to make a “wink-detector” from a modified AD8232 ECG (electrocardiogram) sensor, an LM324-N quad op-amp, an Arduino Uno R3, and a home-made head-band. The detector has two outputs … one for when you wink your left-eye …

SPWM Generator Module (without Using Microcontroller)

“Hello everyone,welcome to my instructable! I hope you all are doing great. Recently, I got interested in experimenting with PWM signals and came across the concept of SPWM (or Sinusoidal Pulse Width Modulation)where the duty cycle of a …

Music Sensor

“There is no better components than LEDs So in this project i just made a Music Sensor that dances with the SOUND !!”

Arduino based Multimeter

“In this tutorial we will merge all the parts seen in these past tutorials here. In those tutorials we have seen how to measure resistance, current, indcutnace and capacitance. Measure voltage is very easy. In this tutorial we make a …

PCB BOT (Line Following, Obstacle Avoiding & Bluetooth Controlled Robot in a Single PCB)

“Lots of line followers are available on the internet. Most of them are made using separate modules. Several single PCB designs are available but all three functionality like Bluetooth control, obstacle avoiding and line following is not available in a …
