The present Medical Electronics deals with many technologies like ECG (Electro Cardio Gram), EEG (Electro Encephalo Gram), Cardiac monitors, etc. Almost all multispecialty hospitals equipped with modern technologies are coming from Electronics.Let me introduce here a heartbeat monitor project that can monitor the heartbeat and displays in a…
These days home security systems are given great importance everywhere. However, these security automation systems are very expensive to implement. Here I will help you to make a simple IR security system on your own using an Infrared-photodiode pair. Earlier…
Have you seen Audi, Lexus, or Ford automatic rain-sensing wipers and wondered how they work in these vehicles? They are handled by sensors at the center of the windscreen which detect rainwater and turn the wiper motor on. Here is the working…
Mosquitoes are one of the most irritating bugs and they spread many diseases. Here we are talking about a method that would most likely drive the mosquitoes away with the help of certain frequency generators. Researchers have found that insects are typically allergenic to…
Here we are going to discuss a simple timer IC 555 project. The 555 timer IC can be used as an audio amplifier with an astable multivibrator configuration. It functions to carry out pulse width modulation (PWM) of the audio signal. The Current(I) capacity of the 555 timer…
Here is an LPG gas leakage sensor alarm circuit that detects the outflow of LPG gas and alerts the user via audio and visual indications. The heart of this simple engineering project circuit is a gas sensor module SEN-1327. MQ-6…
Today Electronic projects for school students are an essential part of their academics. These educational science experiments for kids boost their skills and analytic power rapidly to a great extent. But most of the parents and students worry about how to make…
Snap your fingers to let happen what you want! Yes, that’s what we have ahead: at least in the realm of electrical and electronic appliances. I’ve used 555 timer to avail the monostable multivibrator functionality and 7474 D-flip flop to…
