Robotics day 2- Ambulance siren+burglar alarm

On my second day, I was able to complete two tasks. first is an ambulance siren, which uses 1 LED light, 1 buzzer, an Arduino board, jumper wires, and a USB cable. This project was coded to make the LED light turn off and on when the buzzer is making noise.

The second project was a burglar alarm, which used the same equipment used in the first task plus an object sensor. The project was programmed so that if an object or person is in front of the object sensor, the buzzer will make noise and the LED light will start blinking continuously.
