Example Code for Arduino-Serial Output

Hardware Preparation

• 1 x DFRduino UNO R3
• 1 x IO Expansion board
• 1 x Thin-film pressure sensor
• 1 x Digital cable

Software Preparation

• Arduino IDE

Wiring Diagram

Connect the sensor to the A5 pin on the expansion board.

Sample Code

void setup() {
Serial.begin(9600);
}
void loop(){
Serial.println(analogRead(A5));
delay(500);
}

Result

When no pressure is detected
When pressure is detected
