OBJECT/VISITOR COUNTER [ELECTRONICS MINI PROJECT]: The idea behind this to project is to Count the Objects/Visitors and display the number of object or visitor on seven segments display. As a Student, to understand this project and to solder all of the components according to the circuit will make you feel confident. HOW DOES IT WORKS: There are two types of led shaped sensor included in the project. One is called Tx IR LED(White) and the other one is called Rx IR LED(Black). White led is used to transmit IR(Infrared) signals and black led is to receive the IR signals coming from the White Tx LED. Both LED's placed in face to face position. The Rx LED is connected to the Base terminal of the transistor. Whenever, any Object or Visitor passes out in between of the pair, The base terminalgof transistor gets an low power input pulse further, which amplified by the transistor at the output terminal of the Transistor. Output of transistor is coupled with the IC4026(7 Segment Driver) to display the number of object or visitor on the 7 Segment. With this complete box, we are providing one complete working project on breadboard and one more set of all the electronics components(Raw Components) of the same project for soldering practice. For reference, students can see how components are connected in breadboard (working model). Then they can make project on PCB their self with using soldering gun. Note that the PCB given with this project is totally hand made. For easy and interactive learning, we are also providing a neat & clean circuit diagram of the project. You can see the demo of this working modal here https://youtu.be/LuzUc1-MWfM and after connecting all the components on PCB its look like this https://youtu.be/YGM8j6TqLno. In This Box you will find 2-IC 4026 , 2-TRANSISTOR , 1-HAND MADE PRINTED CIRCUIT BOARD (PCB) ,2-Pairs IR TX RX LED, 1-RECHARGEABLE POWER SOURCE, 6-ASORTED RESISTORS, 1-COMPLETE WORKING MODEL ON BREADBOARD.
