Car Warning Tone Generator for Ignition, Headlight, Turn Lights
The circuit explained here is basically a warning signal generator designed largely for automobile application. It triggers a warning signal in a situation when the turn indicator switch is not restored back to its neutral status. The circuit is especially useful for all those cars where the turn indicator system is not supported with an […]
Ice Warning Circuit for Automobiles
Devices that react to variations in atmosphere or fluid heat are simple to construct due to the easy availability of thermistors. This car ice warning circuit explains how to implement a thermistor like a transducer in a circuit that continuously blinks a warning lamp as soon as the atmospheric temperature drops to around 0 °C. […]
Ultrasonic Fuel Level Indicator Circuit
An electronic device or circuit which detects and indicates the various fuel levels in a fuel tank without a physical contact, through ultrasonic waves, is called an ultrasonic fuel level sensor In this post I have explained how to build a simple fuel tank level indicator circuit using Arduino and ultrasonic sensors. In every vehicle […]
Motorcycle Button Start Locking Circuit
In this post I have explained how to modify an existing button start system in motorcycles so that it’s disabled as soon as the engine has started and gained the required minimum amount of RPM. The idea was requested by Mr. Jordan Circuit Requirements I just discovered your splendid site/blog with focus on education about […]
