Force Pad Interfacing with Arduino

Force Pad Interfacing with Arduino

Force pads are designed to detect when Force is applied to an area, and they come in a variety of quality and accuracy. The simplest Force pads are often the equivalent of big switches. Inside a Force pad are two layers of foil separated by a layer of foam with holes in it. When the foam is squashed, the metal contacts touch through the foam and complete the circuit.

Code :-

//Prateek //www.prateeks.in #include <LiquidCrystal.h> LiquidCrystal lcd(13, 12, 11, 10, 9, 8); float cf = 19.5; // caliberation factor int ffs1 = A0; // FlexiForce sensor is connected analog pin A0 of arduino or mega. int ffsdata = 0; float vout; void setup() { Serial.begin(9600); lcd.begin(16,2); lcd.print("WWW.PRATEEKS.IN"); delay(1000); pinMode(ffs1, INPUT); } void loop() { ffsdata = analogRead(ffs1); vout = (ffsdata * 5.0) / 1023.0; vout = vout * cf ; Serial.print("Flexi Force sensor: "); lcd.setCursor(0,0); lcd.print("Force Range: "); delay(100); lcd.setCursor(0,1); lcd.print(vout,3); lcd.print(""); lcd.print(" Gram"); Serial.print(vout,3); Serial.println(""); delay(100); }
