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 […]
Newly Updated Circuit Projects:
Compact 3-Phase IGBT Driver IC STGIPN3H60 – Datasheet, Pinout
In this post I have explained the datasheet, and the pinout specification of the IC STGIPN3H60 from ST microelectronics, which is perhaps the slimmest and the smartest 3-phase IGBT driver IC featuring in-built IGBTs, rated to work with 600V DC bus and upto 3 amp current, that’s equivalent to almost 1800 VA handling power. 3-Phase IGBT […]
Patient Drip Empty Warning Indicator Circuit
In this post I have explained about a simple mechanism, and a circuit which will enable a patient’s IV drip bottle system to sound an alarm whenever it gets almost empty, and needs a replacement. The warning circuit will help doctors and the concerned employees to concentrate on other important matters while the drip systems […]
PIR Sensor Datasheet, Pinout Specifications, Working
In this post I am going to explain the datasheet of PIR or Pyroelectric Infrared Radial Sensor HC-SR501. We will understand for what purpose PIR sensor is used? Its basic trigger operations, pin connection details, technical specifications and finally we will be looking at some real life applications. We will begin by understanding the actual […]

If you are having difficulty in understanding how to use an LM3915 IC, this article will help you to easily construct any desired applicable circuit using this IC. Here, I will elucidate the datasheet of the IC LM3915, its pinout functions, its main electrical specifications, and also a few useful application circuits. General Description The […]
Triacs – Working and Application Circuits
A triac can be compared to a latching relay. It will instantly switch ON and close as soon as it’s triggered, and will remain closed as long as the supply voltage remains above zero volts or the supply polarity is not changed. If the supply is an AC (alternating current), the triac will open during […]
