Tick Tock Shield Archives

Here is a picture of the Tick Tock Shield, this shield is ideal for beginners as it has several components such as a buzzer, LDR, LEDs, temperature sensor, buttons and 7 segment displays.

In this example we will get the temperature from the on board sensor, the sensor is connected to A0 and we will see the temperature via the Serial Monitor output

Code

[codesyntax lang=”cpp”]

#define TEMPERATURE_SENSOR 0

void setup()
{
  Serial.begin(9600);
}

void loop()
{
  float temperature,resistance;
  int a;
  int B = 3975;
  a = analogRead(TEMPERATURE_SENSOR);
  resistance   = (float)(1023-a)*10000/a; 
  temperature  = 1/(log(resistance/10000)/B+1/298.15)-273.15;
  Serial.println(temperature);
  delay(500);
}
