-===== Lab 1 ======
+===== Lab 1: Getting Started ======
 ===== Necessary gear =====
-We will be using the ESP32 Sparrow board as the main development board for the lab assignments.
+We will be using the [[https://github.com/dantudose/ESP32-Sparrow-rev2/tree/main| ESP32 Sparrow]] board as the main development board for the lab assignments.

 Also, for the first labs, we will be using the Arduino IDE and environment, which you can download from  [[https://www.arduino.cc/en/software|here]]
+===== ESP32 Sparrow specs =====
+This is the pinout diagram of the development board:

+To get everything set-up, please use the [[https://randomnerdtutorials.com/installing-the-esp32-board-in-arduino-ide-windows-instructions/
+| this tutorial]] to install ESP32 support in Arduino, the only difference is the board type should be set to ESP32 WROVER.
+===== First Steps =====
+=== 1. Blink the on-board LEDs ===
+Open the "Blink" example in the Arduino IDE
+{{:iothings:laboratoare:lab1-blink.jpg?600|}}
+Define LED_BUILTIN to correspond to one of the on-board LEDs.
+For the <color green>GREEN boards </color> (rev. 1) the LED has the following pinout
+  * Red - GPIO25, Green - GPIO26, Blue - GPIO27
+And for the  <color blue>BLUE boards </color> (rev. 2), the LED has the following pinout:
+  * Red - GPIO14, Green - GPIO13, Blue - GPIO15
+<code>
+#define LED_BUILTIN ...
+</code>
+=== 2. Scan and display local WiFi networks ===
+Load the "WiFiScan" example from Arduino IDE.
+{{:iothings:laboratoare:lab1-wifi-scanner.jpg?600|}}
+Open the Serial Monitor to view the result of the scan
+{{:iothings:laboratoare:lab1-serial-monitor.jpg?600|}}
+=== 3. Advertise on BLE  ===
+Load the "SimpleBleDevice" example. Install on your phone an app that scans nearby Bluetooth devices, such as this [[https://play.google.com/store/apps/details?id=com.macdom.ble.blescanner&hl=en&gl=US|BLE Scanner]]. Check if your device is in the list.
