To begin with, this Pressure Sensor Alarm Circuit talks about one electronic device which can feel when pressure goes up or down. Think of a one special plate like doormat, pressure increases when someone steps on it; or if there is a change in air pressure inside the machine then this device is capable of […]
Simple Light Operated Relay Circuit
Simple Light Operated Relay Circuit work like small auto light switch, as it uses special sensor like LDR or photo diode which work like small eye. Furthermore, when light appears sensor gives signal to the circuit and then circuit turn the relay ON or OFF; and this help for turning outside light at night or […]
NiMH Battery Charger Circuit
This NiMH Battery Charger Circuit is like special water can for NiMH batteries which are the same batteries inside camera, toy and other devices. Normal charger maybe not be so good for these batteries but this NiMH charger circuit give just right power and make battery work good and last long time. Circuit Working: Parts […]
Simple Vibration Sensor Circuit
A Simple Vibration Sensor Circuit works like a small motion detector for electronics, it senses shaking or sudden movement and then sends an electrical signal. Furthermore, this type of circuit is good for use in thief alarm to feel someone come in or for earthquake to feel ground move; also, we can use it in […]
Simple Rain Sound Effect Generator Circuit
This small and Simple Rain Sound Effect Generator Circuit it like a rain sound maker in box, as it uses electric parts to make sound and almost same like real rain drop. Also, this soft sound are good for many things like background music or sleep timer or help us in dreaming. So next time […]
Simple Adjustable Zener Diode Circuit
Think like small switch which controls how much voltage go through. A normal Zener diode works like a fixed switch that allows electricity to pass only when the voltage rises above a certain level, but this Simple Adjustable Zener Diode Circuit works more like a flexible dimmer switch. We can also change voltage level using […]
