We have already discussed many circuits to remote control home appliances. But they’re Infrared controlled and have many limitations. Today, in this article, we will be discussing how to use a cheap single-channel RC toy car’s RF module to remote control home appliances. We are also are going to discuss how to control 2 AC […]
Hello Engineers, hope all are great! In this article, we are going to discuss an IR proximity sensor circuit using TSOP 1738 IR receiver. This circuit was made at the request of one of our visitors and is immune to outdoor light or sunlight. This circuit is a bit different than the usual circuits for […]
Hello Engineers. Hope all are good. Here in this article, we are going to discuss how to make your own adjustable time Traffic light controller circuit without the use of any microcontroller. A traffic light controller basically controls the operation and timing of the traffic signal lights according to a set time. Here we are […]
Hello Engineers. In this article, we’re going to talk about making a Piano using IC 555. This will be a simple and very well working mini piano using IC 555 and some other passive components like resistors, capacitors, etc. Sound travels by the to & fro displacement of the particles of the medium. Sound waves […]
Hi guys. In this article, we are going to discuss a very simple metal detector circuit using IC 555. The circuit also uses some other active and passive components with IC 555, like coil and Buzzer for the indication and alert. So, let’s get started with our metal detector circuit using 555 IC. There are […]
