4 Digit Object Counter

If you’re looking to build a 4-digit object counter from scratch, you’ll need a few basic components:

1. Microcontroller: The brain of your circuit. You can use an Arduino, Raspberry Pi, or any other microcontroller that you’re comfortable working with.
2. 7-Segment Display: A 7-segment display is a type of electronic display device that can display numeric digits and some letters. You’ll need a 4-digit 7-segment display to display the count.
3. Sensor: You’ll need a sensor to detect the presence of objects. There are several options available, including IR sensors, ultrasonic sensors, and magnetic sensors.
4. Resistors: You’ll need a few resistors to limit the current flowing through your circuit.
5. Capacitors: Capacitors help stabilize the voltage and reduce noise in your circuit.
6. Breadboard: A breadboard is a tool that allows you to prototype circuits without soldering.
7. Jumper Wires: You’ll need jumper wires to connect the components on your breadboard.

Once you have all the components, you’ll need to write the code for your microcontroller. The code will need to read the sensor and increment the count each time an object is detected. You’ll also need to write code to display the count on the 7-segment display. There are plenty of tutorials and examples available online to help you get started.
