===== 2. Setup Development Environment =====

  - Download and Install Arduino IDE from the [[https://docs.arduino.cc/software/ide-v2/tutorials/getting-started/ide-v2-downloading-and-installing/|Download Page of Arduino]] and follow the official [[https://docs.arduino.cc/software/ide-v2/tutorials/getting-started/ide-v2-downloading-and-installing/|Installation instructions]].
  - Our board is the [[https://www.wemos.cc/en/latest/d1/d1_mini.html| WEMOS D1 Mini ]] and it is based on the **ESP8266** microcontroller from Espressif. Since the board is not produced by Arduino (company) it is not pre-installed in the Arduino IDE (software), however it is possible to install the add-on that allows us to program it using the entire Arduino ecosystem. To do so follow the instruction on the section [[https://randomnerdtutorials.com/installing-esp8266-nodemcu-arduino-ide-2-0/ |"Install ESP8266 NodeMCU Add-on in Arduino IDE 2"]] 
  - [[https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers (Win, MacOS, Linux) | How to install CH340 driver]] - [[https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers#drivers-if-you-need-them|Driver Download Section]]

===== 3. Hardware Review =====

  * Dev-Kit: [[https://www.wemos.cc/en/latest/d1/d1_mini.html| WEMOS D1 Mini ]]
  * Microcontroller: ESP8266 12-E Chip. For more details of the microcontroller and board check the link [[https://randomnerdtutorials.com/getting-started-with-esp8266-wifi-transceiver-review/| ESP8266 hardware review]]

===== 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>
