TV Remote Control Tester Circuit

Remote control tester circuit using an opamp

We all use remote control handsets for controlling various household devices such as TV, AC, Music systems, curtains etc, and sometimes we seem to have problems with these devices, or even a newly purchased remote controller unit occasionally seem to malfunction, and identifying the issue becomes quite difficult for us. This simple 2 transistor circuit … Read moreTV Remote Control Tester Circuit

Make this IR Remote Control Range Extender Circuit

433MHz transmitter circuit with infrared TSOP1730 IC

In this post we will learn how to increase or extend the range of an ordinary infra red or IR remote control through a 433MHz RF remote control system. IR Range Extender Concept The idea of this circuit is to feed the IR data from an IR transmitter into the transmitter input of an RF … Read moreMake this IR Remote Control Range Extender Circuit

Using TSOP17XX Sensors with Customized Frequencies

We know that the center or band-pass operating frequency of a TSOP17XX IR sensor is assigned to a particular frequency which makes it difficult to use these sensors for designing unique or customized frequency based remote control circuits. In this post we will try to figure out an idea for enabling these sensors to work … Read moreUsing TSOP17XX Sensors with Customized Frequencies

Mp3 Player Using DF Player – Full Design Details

In this post we are going to construct an Mp3 player using arduino and DFPlayer. The proposed article has two Mp3 player designs, one with push button control and another one with IR remote control. We will also take a look at DFPlayer (Mp3 player module) and its specifications. By Arduino Guru  We all love … Read moreMp3 Player Using DF Player – Full Design Details

Controlling LED Strip Light ON/OFF and Brightness with any Remote Control

In this post we are going 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 ribbon … Read moreControlling LED Strip Light ON/OFF and Brightness with any Remote Control
