LED ON and OFF Circuit using 555 Timer IC Building a LED Dimmer Circuit using 555 Timer IC and BC557 Transistor

LEDs are commonly used in electronic circuits as they consume less power, are easy to use, and have a long lifespan. In this tutorial, we will learn how to build an LED ON and OFF circuit using 555 timer IC and BC557.

Required Components

Before we get started, let's understand the components we will be using in this circuit.

Missing Pulse Detector Circuit Missing Pulse Detector Circuit

When a signal goes through a sudden change from base value to higher value and again comes to base value from higher value after some time. It is called a Pulse signal.

In above image, the first waveform shows a single pulse where the signal is changing from 0 to 5v (low to high) and 5v to 0 (high to low) within a short…

Wireless DC Motor Speed Control using IR Remote and 555 Timer IC Wireless DC Motor Speed Control using IR Remote and 555 Timer IC

In this project, we are going to Control the Speed of Dc Motor Wirelessly Using IR or TV Remote Control. Here we are not going to use any microcontroller. We have used basic components along with 555 Timer IC to complete this task. This circuit can control the DC motor speed in 5 different levels and any IR remote like TV/DVD remote etc can be used to control it.

Infrared Detector Circuit using 555 Timer IC IR Detector Circuit using 555 Timer IC

Infrared sensors are much common in our electronics life. They are used in many real time applications like for opening and closing the gates at Metro Station. Even they are used in our Mobile phone to turn off the display light during the call.

IR sensor is very popular sensor, which is frequently used in many applications in electronics, like it…

IR Transmitter and Receiver Circuit How to build a Simple IR Transmitter and Receiver Circuit using 555 Timer?

IR Transmitter and IR Receiver are commonly used to control electronic devices wirelessly, mainly through a remote. TV remotes and AC remotes are the best example of IR transmitters. TV generally consists of TSOP1738 as the IR receiver, which senses modulated IR pulses and convert them into electrical signal. Here in our circuit we are building IR remote and its receiver.…
