Flashing LED Battery Low Indicator Circuit
In this post I have explained a simple low/normal battery voltage status indicator circuit through a flashing and a constant LED, where the flashing LED indicates a normal status while the solid indicator warns against a low battery condition. The idea was requested by Mr.Alf. Technical Specifications Hi, I found and built your “Low Battery […]
Up/Down LED Indicator using LM3915
This circuit can be used for moving an LED bar graph in the upward sequence or downward sequence through a couple of push button switches. The concept can be implemented for many other useful applications. Using IC LM3915 In many circuit applications we require a digitally operated control system enabling an upward or downward control […]
LED Timer Indicator Circuit for Board Games
In this article I have explained a simple LED indicator timer circuit which can be used with board games for indicating the elapsed time or the time consumed by the player to complete his or her turn. The idea was requested by Mr. Shane Robins. Technical Specifications Hope all is well with you. I am relatively new […]
Controlling LED Strip Light ON/OFF and Brightness with any Remote Control
In this post I will show how to construct LED strip controller circuit using Arduino, which can turn ON/OFF and decrease/increase brightness of LEDs using ordinary IR (Infrared) remote. What is LED Strip Light? (For noobs) If you are not familiar with LED strip lights, let’s understand what it is. LED strips (sometimes called as […]
Ceiling LED Lamp Driver Circuit
Nowadays the CFL and fluorescent lamps are almost completely replaced with LED lamps, which are mostly in the form of circular or square shaped flat ceiling mounted LED lamps. These lamps beautifully merge with the flat ceiling surface of our homes, offices or shops providing an aesthetic look for the lights, along with a high […]
