Simple Music Level LED Indicator Circuit
With the help of this tutorial one can construct an LED circuit that will light up repeatedly in response to changes in music volume. The circuit moves the lights in a wave-like pattern in response to sudden changes in music loudness. The circuits operation and the components required for construction is explored in this article […]
Simple Temperature Indicator Circuit using a Single Transistor
Its not as challenging as one may imagine to build a simple temperature sensor circuit. The article describes how to create one using a single transistor, a diode and a few other basic components. What is a Temperature Indicator Circuit using a Single Transistor: Using a single transistor a temperature indicator circuit is a simple […]
Simple 4 LEDs Water Level Indicator Circuit
Water conservation is a priority and technology like electronic can help. This article teaches how to construct a simple circuit for a water level indicator. It is far less expensive than purchasing one from a store and by using common parts. This circuit shows the water level remaining in a tank or barrel using LEDs. […]
Simple IC LM35 Temperature Indicator Circuit
Keeping track of temperature is important for a lot of things but sometimes it does not need a fancy computer to do it. This article discusses how to build a simple temperature sensor with an LED light using a common chip called the IC LM35. It only uses a few parts and does not need […]
3 LED Battery Voltage Level Indicator Circuit
A healthy battery is important for the car or any machine with a battery to run well and avoid problems. This post shows how to build a tool that checks the battery voltage and informs if it is low, good or overcharged. It works with most 12V car batteries but with a small change one […]
