+# Day eight:
+
+Challenge!! Who will get the lowest temperature? 
+
+Use the temperature sensor to win, upload a picture of the temperature printed on Serial and a picture of the situation. It's not allowed to put the Barduino in the fridge... 😜 Give it some time for the temperature to stabilize, it can take up to 15 minutes.
+
+Tip, you can power the board with you phone and read the Serial there with an app in [Android](https://play.google.com/store/apps/details?id=de.kai_morich.serial_usb_terminal&hl=en&gl=US&pli=1) (I don't know if that's possible with iPhones).
+
+## Possible solution!
+
+### Arduino code
+
+```c++
+#include <Temperature_LM75_Derived.h>
+
+TI_TMP102 temperature;
+
+const int push = 0;
+bool pressed = false;
+
+void setup() {
+  pinMode(push, INPUT);
+  Serial.begin(115200);
+  Wire.begin();
+}
+
+void loop() {
+  if (!digitalRead(push) && !pressed) {
+    pressed = true;
+    Serial.print("Temperature = ");
+    Serial.print(temperature.readTemperatureC());
+    Serial.println(" C");
+  } else if (digitalRead(push)) {
+    pressed = false;
+  }
+}
+```
