Initially, it will print “Arduino Timer” on the LCD display until you press the pushbutton. As soon as you press the pushbutton, it will ask to enter countdown time duration by calling the “setFeedingTime” function. Then you can enter the time duration with the help of Keypad. Then...

Time-Locking Mechanism: Set a countdown timer using the rotary button. Once the time is set, the box locks automatically and cannot be reopened until the countdown ends. LCD Screen: Displays the countdown timer so you know how much time remains until the box unlocks. Rotary Button Control:...
forward; allow the user to set the desired exposure time via the potentiometer, turn on the LEDs, and initiate the countdown process with the progress being displayed on the LCD. When the preset time is reached, turn off the LEDs and initiate a beep on the buzzer so the user is ...
A push button is a simple tactile switch that makes or breaks electrical contact when pressed. This can be used to initiate a variety of different effects depending on the project. For example, you could roll dice (for display on an LCD or dot matrix), sound a piezo buzzer, or start/st...
