I have a basic set up of having a force sensitive resistor being used to power an LED as can be seen below. I am wondering how I can code it so that the LED is lit after a pressure has been applied to the FSR for a specified amount of time. Leading on from that I would like to use an RBG LED and have it so that after specified intervals on continuous pressure the LED changes colour. Any advice would be greatly appreciated.
//Constants:
const int ledPin = 3; //pin 3 has PWM funtion
const int sensorPin = A0; //pin A0 to read analog input
//Variables:
int value; //save analog value
void setup(){
pinMode(ledPin, OUTPUT); //Set pin 3 as 'output'
Serial.begin(9600); //Begin serial communication
}
void loop(){
value = analogRead(sensorPin); //Read and save analog value from potentiometer
Serial.println(value); //Print value
value = map(value, 0, 1023, 0, 255); //Map value 0-1023 to 0-255 (PWM)
analogWrite(ledPin, value); //Send PWM value to led
delay(100); //Small delay
}
const int ledPin = 3; //pin 3 has PWM funtion const int sensorPin = A0; //pin A0 to read analog input
//Variables: int value; //save analog value
void setup(){
pinMode(ledPin, OUTPUT); //Set pin 3 as 'output' Serial.begin(9600); //Begin serial communication
}
void loop(){
value = analogRead(sensorPin); //Read and save analog value from potentiometer Serial.println(value); //Print value value = map(value, 0, 1023, 0, 255); //Map value 0-1023 to 0-255 (PWM) analogWrite(ledPin, value); //Send PWM value to led delay(100); //Small delay
}
