“Power supplies are one of the most popular topics in electronics. There are two major types of regulated power supply: linear and switching. Both power supply types introduce some advantages and disadvantages, however, a linear power supply offers better line …
“Hello there! I hope you all are fine and in good health. This instructable is about making your own current sensor that is compatible with Arduino and most other widely popular microcontrollers. This project features a compact design and an …
“The idea of making a VU meter has been on my project list for a long time. And finally I can make it now. The VU meter is a circuit for an indicator of the audio signal strength. The VU …
“You may have seen many light-sensitive switch circuits based on an LDR sensor. Usually, the sensitivity of the LDR based light sensor is poor. We wanted a very sensitive light switch hence we decided to make a circuit based on …
“This is an isolated analog input module that is useful for interfacing Analog signals of various types originated from analog sensors and field devices. The module is very useful for in-process controls, factory automation, industrial applications, etc. Interfacing an analog …
“This pressure switch project is built using a piezoresistive transducer, LM358 OPAMP as comparator, and a relay. The circuit activate the relay when the pressure in a system exceed a given set-point. Basically, this switch can power ON or OFF …
“A sensor is a device that detects and responds to inputs from the physical environment. The input can be light, heat, motion, moisture, pressure, or any other environmental phenomena. Sensors are very important part of electronics, especially in Robotics and …
“So on my Youtube channel, many people ask how to combine two amplifiers into one. The first amplifier is used for satellite speakers and the second amplifier is used for subwoofer speakers. This amplifier installation configuration can be called Amplifer …
“Hi everyone. If you’re like me you, probably have a bunch of spare sensors lying around either from incomplete projects, or that you bought on a whim for some reason or another. I was inspired by Patrick Panikulam’s …
“In this project, we will make an automatic on-off water tap under $5 only. We will use an IR sensor and a water switch to make this automatic infrared water tap. No microcontroller is used to make this automatic infrared …
