IR Transmitter and Receiver Circuit diagram

HOW TO MAKE REMOTE CONTROL LIGHT USING BC547 This is a simple project. Here we have used infrared communication, its simple meaning is that ir led is used for transmitter and ir receiver module is used for receiver. It is a single channel transceiver, we can activate and deactivate an output. We have used NE555 timer IC in transmitter circuit and receiver used only transistors. And its transmission distance is quite good as we feel at home TV remote. This project is going to be very educational for the beginners and if you want to make this same project using only transistors then you can comment's us and we will help you as much as possible. Necessary ingredients :- 555 timer IC -1no IR receiver (STOP1738) -1no IR led -1no 5V DC relay -1no Transistors BC547 -4nos(Q1-Q4) Transistor BC557 -1no(Q5) Green LED for OFF indication -1no Red LED for ON indication -1no Circuit OFF/ON Switch -2nos 3.7v to 5v Battery -2nos CIRCUIT DIAGRAM :- What is transistor There are several types of ...

Long Press ON/OFF Switch using BC547 | Push Button Long press On/Off function.

Long Press ON/OFF Switch using BC547 | Push Button Long press On/Off function. We all know that switch plays an important role in electrical circuit , and electrical engineering is impossible without switch. A switch is an electrical device and its function is to turn an electrical equipment on or off, also we can say it is used to connect or disconnect two circuits. Currently there are different sizes, types of switches. The switch we have made here follows the POWER OFF and ON of the Android phone and it has been used in many devices other than the Android phone such as computer, mobile, bluetooth music system, smart watch, etc. This switch plays an important role in terms of safety as if someone accidentally presses the switch normally then it will not work, it will work only when you press and hold the switch like I do when switching on the mobile. History of the Switch:- In October 1879, Thomas Edison invented the first carbon filament light bulb, but the issue of the switch h...

How to make remote control home led bulb | smart led bulb at home

How make smart led bulb|remote control led bulb. Hello gays welcome to Logic Science, so today we will learn how to make smart led bulb from simple led bulb.To make this project we need a led bulb which we use at home, but here the led bulb we will use is a little different, this led bulb does not have ac to dc power supply circuit board and why is not used is explained below. Adapter based LED bulb We don't used this type of led bulb in this project,Because there is very little space left inside this led bulb, and we cannot install our circuits inside the bulb, so we are not using this kind of led bulb. But you can make this bulb a remote control, in that case you need to insert the remote control circuit into the switch board. LED bulb without Adapter We only used this type of led bulb in this project, Because we get a lot of space inside this led bulb and we can easily install our circuits inside the bulb. This type of led bulb consists of main two electrical compon...
