7. 7. Connect the pull-up resistor (4.7kΩ) between the CS pin and GND.
8. 8. Verify the connection with a multimeter.

Example code

```cpp
#include <MAX31865.h>

MAX31865 tempSensor(10, 11, 13);

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

void loop() {
  float temperature = tempSensor.readTempC();
  Serial.println(temperature);
  delay(1000);
}
```

Mini project

Create an automatic heating system for a room. Measure the temperature with the detector and turn on/off a thermostat based on a predefined temperature value.

Common mistakes

• Forgetting to connect the pull-up resistor.
• Power the detector with a voltage level different from 5V.
• Connect the CS pin to VCC instead of GND.
• Forget to check the connection with a multimeter.

Recommended accessories

• Digital thermometer
• Thermostat
• Arduino UNO
• Check the datasheet.
