| Code Description: | Code Description: | ||
| + | - libraries for servo motor and sensors are included | ||
| + | - components' pins are declared | ||
| + | - setup() function: data pin of the servo motor, INPUT pins(ECHO) and OUTPUT pins(TRIGGER) are configured | ||
| + | - loop() function: firstly it verifies if there is any fire inside the trash can(if yes, sends a message), then checks if the trash can is full(if yes, sends a message) and then the servo motor opens the lid if the distance between hand and lid is less than 10 cm. | ||
