Control a Fan and Light by a TV Remote, Circuit Diagram Download 2023

Hello friends, how are you all? Today I will show you how you can turn off your house light fan TV without a switch. If you want me to control all the electronic devices in the house without a switch, then read this post completely, and you will get all kinds of information. Let’s begin.

Working Circuit Diagram Explanation

We will learn how to make a TV remote control controlling a fan and light with 4017 ic. The 4017 ic is a decade counter that can produce 10 different outputs depending on the input pulse. We will use an infrared receiver module to receive the signals from the TV remote and feed them to the 4017 ic. The 4017 ic will then activate a relay switch that will turn on or off the fan and light.

The circuit diagram of the project is shown below. We need the following components:

• BC547 Transistor
• 220-ohm Resistor
• Red LED
• 1N4007 Diode
• 1K Resistor
• CD4017 ic
• 5V Relay 8)
• 1uF 63V Capacitor
• IR Receiver Module (LFN)
• IR Remote

The working principle of the project is:

• The IR receiver module receives the signals from the TV remote and converts them into electrical pulses.
• The pulses are fed to the clock input of the 4017 ic, which counts them and produces a corresponding output.
• The output of the 4017 ic is connected to a transistor, which acts as a switch for the relay module.
• The relay module controls the power supply to the fan and light bulb.
• By pressing different buttons on the TV remote, we can change the output of the 4017 ic and thus control the fan and light.

For example, if we press the button “1” on the TV remote, the output Q0 of the 4017 ic will be high, and the transistor will turn on. This will activate the relay and turn on the fan. If we press the button “2”, the output Q1 of the 4017 ic will be high, and the transistor will turn off. This will deactivate the relay and turn off the fan. Similarly, we can use other buttons to control the light bulb.

The project is simple and fun to make. It can be used as a demonstration of how a TV remote can be used for other purposes than controlling a TV. It can also be modified to control other devices or appliances using different codes or frequencies.

Can I control my old fan with the TV remote?

You can control your old fan with the TV remote, but you will need some additional devices and steps to do so. Here are a few methods that could be used to do this:

• If your fan has a remote control, you can use a product called Bond Bridge to learn and use the frequencies of your fan’s remote and control it with your TV remote or a smartphone.
• If your fan does not have a remote control, you can install a universal ceiling fan remote control kit in your fan’s housing and then use the Bond Bridge to control it with your TV remote or a smartphone.
• If you want to control your fan with a wall switch, you can replace your existing switch with a smart ceiling fan wall switch that allows you to control the fan and its lights with a touch panel, a smartphone, or a voice command device.
• If you want to control your fan with a smartphone app, you can plug your fan into a smart WiFi plug⁶ that allows you to turn it on or off remotely or set timers and schedules.
