Robotics day 18- Bluetooth connection (HC-05)

In today's class, we began with a new topic, the Bluetooth connection. This project required the HC-05 board, which is the connection board between the Arduino and phone. We started by opening a new piece of software called the Arduino Lock, and what I liked and found very useful about this platform is that it can automatically turn blocks into written form. This means any block can be translated into words. After we finished the code, we copied and pasted it into the Arduino IDE. After uploading the project and connecting the LED light, we had to download the app. This app is only available on Android and is called "Arduino Bluetooth Control." The up arrow was for on, and the down arrow was for off. Unfortunately, the opposite took place, but this is an error we will fix next class.
