Introduction: Distance Measurement With 2.4 Ftf and Ultrasonic Sensor
this is very simple arduino circuit with HC-SR04 ultrasonic sensor and 2.4 inch tft display, powered by arduino uno.
the arduino uno calculate the distance and update the display every 1 second.
watch this video to see how it works.
Step 1: Tools and Parts
the only tool we need is a pc with arduino IDE.
in this example we use the Adafruit_GFX library to use the tft display.
required parts:
1 ARDUINO UNO + 2.4 TFT (you can use any arduino you want..)
1 6v battery or power supply
Step 2: Conecting and Coding
the tft shield can fit to the arduino but the ultrasonic need some wires.
connect the ultrasonic sensor trigger pin to the arduino pin 11
connect the ultrasonic sensor echo pin to the arduino pin 10
connect the ultrasonic sensor vcc to 5v
connect the ultrasonic sensor gnd to the gnd
upload the code and make a test
