Arduino Object Counter using TCRT5000 Sensor and TFT Display

Overview

This Arduino-based project uses a TCRT5000 infrared sensor to count detected objects and displays relevant statistics on a 1.8" TFT screen using the Adafruit ST7735 library. An optional push button can be used to manually reset counters.

Features

• Object Counting: Increments the counter when the sensor detects an object.
• TFT Display: Shows total count, objects per minute/hour, and elapsed time.
• Auto Reset: If the sensor is continuously triggered for a set time, the system resets.
• Manual Reset: A push button allows manual resetting.

Components Used

• Arduino Nano
• TCRT5000 Infrared Sensor
• 1.8" TFT Display (ST7735)
• Push Button for manual reset (optional)
