-
The code defines various pin numbers for the different components used in the system, such as conveyors, sensors, actuators, and indicators.
-
Boolean variables (s1-s41) are declared and initialized to manage the system's state and control its operation.
-
In the
setup()function, the pin modes are set for input and output pins to configure the system's components. -
The
loop()function is the main program loop that executes continuously. -
Within the
loop()function, a series of conditional statements are used to control the sequence of operations in the metal detecting system. -
Each conditional statement checks the current state (
s1,s2, etc.) and performs the corresponding actions based on sensor readings and system logic. -
The actions include controlling outputs to drive conveyors, actuating cylinders, operating grippers, setting indicator lights, and delaying specific time intervals.
-
After executing an action, the current state (
s1,s2, etc.) is updated to transition to the next state in the sequence. -
The code continues to loop and execute the subsequent states and actions until the desired process flow is completed.
-
The sequence of states and actions defined in the
loop()function represents the overall logic and control flow of the metal detecting system using the conveyor belt.
