Here, we have given idea about very very simple voltage level indicator with different two ways.voltage level indicator with resistors and voltage level indicator with zenor, Both circuits are very simple and informative specially for the students who are beginners in the field of electronics. |Read More|
People use coils, mats,creams, liquid as Mosquito repellents at various places. However these repellents almost become the cause of dangerous diseases like skin cancer, breathing problems etc. That is way Electronic Mosquito repellent is best to protect your homes instead of other repellent. We have made this circuit with 555 timer ic to generates the ultra sonic sound for Mosquito Repellent. |Read More|
This circuit is about water level indicator by using transistors you can also make this circuit by using switching ic 2003. Water level tester is very important circuit to save the water wastage. you can also connect relay with this circuit to control the level of water in water tank. |Read More|
Fire Alarm Circuit is a circuit that detects the fire and activates the Siren alarm connected with the circuit. Fire Alarm Circuits are very important devices to protect the people or property from damage. In this article we have built this circuit just with single transistor and thermistor (heat sensor). |Read More|
None voltages tester is a device that detects AC voltages without touching the wire or any other objects of AC. In this modern every one use almost all AC appliances. When we check any object we must verify either current is present in it or not. |Read More|
In this project we have designed a very simple Single transistor amplifier. We can use any NPN type transistor in this project. Its very low power single transistor amplifier but reliable for low boosting. The transistor takes input form any source any boost the and give output. |Read More|
In this project we are going to make a led blinker circuit using transistors. This circuit is mostly used in almost electronics projects like timer,blinker etc. Now a days timer ic 555 is using instead of transistors because ic chip(555 timer ic) is easy to use due to embedded circuit same like transistors working.
In this simple and interesting project we have made a very simple inverter circuit. In this circuit we have used transformer from mobile phone charger and transistor from old CFL (saver circuit) and extra we have used 10 ohm resistor which is connected with base. Actually its a oscillator circuit and same like jelly thrift working. /Read More/
In this simple circuit we have build a simple electronics project which detect water of rain and ring an alarm to alert us. This is alarm is very use full for auto cut off current in the rainy season to protect the life of humans. This is basic circuit which is used in water level indicator and auto shut down the water pump.
