Beacon Level Indicator Circuit for Combine Harvester Grain Tanks
In this post I have explained a beacon indicator circuit for combine harvester grain tanks. The idea was requested by Mr. John Bosch. Circuit Objectives and Requirements I would like to retrofit the rotating beacon grain tank level indicator system shown below, to my older combine harvester. The particular part of the system I want […]
LED Arrow Direction Indicator Circuit
The arrow-shaped LED direction indicator circuit utilizing the 74LS164 based IC and a configuration of 14 LEDs arranged in the shape of an arrow is a captivating and visually appealing project designed to create an eye-catching display. This circuit is designed to illuminate the LEDs gradually, forming the shape of an arrow, and once the […]
Sequential Bar Graph Turn Light Indicator Circuit for Car
The article illustrates a simple yet innovative, fancy car turn signal light circuit which produces a rising bar graph sequence effect when switched ON. The circuit idea was requested by Mr. +Bruce Lowry. I have explained more. Technical Specifications I am after a circuit design similar to the LED Bar Graph circuit that is found […]
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 […]
