The post comprehensively discusses a basic Arduino code implementation guide for blinking its on-board LED. The data was built, tested, and written by Jack Franko. CODE: for simply inbuilt LED on pin 13 of ARDUINO BOARD by default it is programed to blink frequently at 50 Mili Seconds as it in description it will […]

Compatible LED Tube Light Circuit for Standard Ballast Fixtures
In this article we will study a simple LED tube light circuit which could be directly replaced with faulty 40 watt T17 fluorescent tubes and fitted directly on the existing fixture. Thus the circuit is compatible with all standard iron ballast fixture assemblies. How Conventional Fixtures are Wired As shown in the below diagram, traditional […]
Bird in the Nest Indicator Circuit
In this post I have explained a simple infrared based proximity sensor circuit which is implemented to study birds and their behavior, by installing the circuit beside artificially made bird nests. The idea was requested by Mr. Jan Simberg. Technical Specifications I hope you have time to read these few lines. First of all thanx […]
Make a Simplest Temperature Indicator Circuit
A very simple temperature indicator circuit can be built by interconnecting a single transistor, a diode and a few other passive components. Using Transistor as a Heat Sensor As we know that all semiconductors have this “bad habit” of changing its basic characteristics in response to ambient temperature changes. Especially basic electronic components like transistors […]
Simple LED Music Level Indicator Circuit
An LED music level indicator is a circuit that will respond to the connected music levels and illuminate a chain of LEDs sequentially in a push-pull switching manner, in accordance with the varying music intensity. Since the illumination level of the switching LED chain appear to extend forward and backward proportionately in response to the […]
Simple Water Level Indicator Circuits (with Images)
A water level indicator is an electronic circuit which indicates the various levels of water inside a tank. This happens when rising or dropping water levels come in contact with the respective water sensors arranged step wise inside the water tank at different depths. In this post I have explained 2 interesting ways to make […]
