===== 4. Soldering =====

Here it gets practical! You need to solder the microcontroller and some of the sensors, which you will need in the next session.

===== 5. Coding Warm-up =====

Now let's check if your Microcontroller works. Also, you will learn how to upload your first sketch. Basic Blink example:

<file cpp Blink.ino>
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(1000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second
}
</file>
