Today I am going to tell you about something that I think will be very important to you. This is something that several people have come to my inbox and asked. I thought of posting this way for everyone to know.

Today we are going to make an IR Counter. That is about a design that can count the number of items packed in an item packing machine and give a maximum limit to be counted. Watch this video to make it clear.

If this is explained with an example (I will tell the same way someone asked me the question),

I have a small manufacturing factory. Items that produce it come out along a belt. A vehicle is stopped at the end of the belt and the product is loaded into the vehicle.

I want to count the number of products that come out through an IR sensor. Also, I need to be able to select the number of products that come out in one day.

Today I am going to tell you how to make an IR Counter that can fulfill this requirement.

This requires us to

Arduino Board * 1 :-

IR Proximity Switch * 1 :-

20*04 LCD Display * 1 :-

I2C Adapter Module * 1 :-

Push button * 4 :-

10K Resistor * 4 :-

Talking about the IR Proximity Sensor Switch, this sensor works by using IR Sensor. Both IR transmitter and receiver are included in this sensor.

This IR Proximity Sensor Switch operates up to a range of 3cm to 80cm. The distance can be changed from 3cm to 80cm by turning the screw behind this. Operates on 5V. Also, when an object is detected, the LED bulb on the back of this sensor lights up.

You can see 3 wires in this IR sensor as brown, blue and black, and the brown wire is used to provide 5V to the sensor, the blue wire is used to provide the GND connection, and the black wire is used to get the signal out from the sensor.

We use a 20*04 size LCD display to display the count and other details. An I2C adapter is used to connect the display with the Arduino board.

In this, the Max Count Level is first selected by a push button and the Done Button is pushed, then when an object moves in front of the IR Sensor, it is counted. After the Max count level that we selected earlier is counted, it will be notified on the display. Also, there is a possibility to count down and reset the count with the other 2 push buttons. Watch the video for more clarity.
