Schmitt Trigger is special type comparator. It gives stable switching even if input signal is noisy or slow. We can use 555 timer IC as Schmitt Trigger. This IC is used in many projects. Schmitt Trigger can give two types of output : normal (non-inverting) and inverted square wave. Next we will learn how to […]

Electroscope Circuit to Measure Electrostatic Charge
One tool for checking static electricity is Electroscope Circuit to Measure Electrostatic Charge. Static electricity happen when object have unbalanced electric charges and electroscope help to know if static electricity is there and it is how much; as it is just simple conductor. Also, when something touches it, then electroscope charge changes and react and […]
Simple Transistor Relay Driver Circuit
Small switch we call transistor is inside almost all electronic thing, but transistor cannot handle big power by itself. So we have used Simple Transistor Relay Driver Circuit which is like a special adapter for transistor and this help small signal from transistor to control big relay switch. Also, with this we can turn ON […]
