Explanation of Multi Mode Programmable Timer

Step 1: Assemble the components

The first step in making a multi mode programmable timer is to gather all the required components. You will need an Arduino Nano, a 16×2 LCD display, a PCB or a breadboard with jumper wires, and a few resistors, relay etc. List of all components provided above. Make sure to carefully follow the wiring diagram provided above to avoid any short circuits.

Step 2: Connect the components

Once you have gathered all the components, it’s time to connect them. First, connect the LCD display to the Arduino Nano using jumper wires if no PCB available. Then connect all other parts one by one according to the circuit diagram provided above.

Step 3: Upload the code

Now you can upload the code to the Arduino Nano. Link of the programming code for arduino is provided in the components list section above or you can access the code by searching for “multi-mode programmable timer using Arduino Nano” online. Copy and paste the code into the Arduino IDE and upload it to the board.

Step 4: Test the timer

Once you have uploaded the code, the timer is ready to use. Then selecting the desired mode on the LCD display. The timer will then operate according to the mode you have selected.




Step 5: Setting up the Timer

The time delay can be set from one second to hundred hours. The timer has 3 buttons, Set Button, Up Button and Down Button as per the block diagram provided above. Up and Down buttons are also used to Start and Stop the timer. To set the mode and delay time, press the Set Button. With the Up and Down buttons, we can change the mode of timer. After setting the mode, press the set button again.

Make setup as per the following instructions:
Set the Seconds of delay time. After setting the Seconds, press the set button again.
Set the Minutes of delay time. After setting the Minutes, press the set button again.
Set the Hours of delay time. After setting the Hours, press the set button again.
With Up and Down buttons, we can start and stop the timer.
This timer can be used in three different modes, which are Type-A, Type-B and Type-C.
Type-A is On-delay timer mode
Type-B is Off-delay timer mode
Type-C is Cyclic timer mode which is ON and OFF timer.

Conclusion of Multi Mode Programmable Timer

In conclusion, making a multi mode programmable timer using the Arduino Nano is a relatively simple process that can be accomplished by following the steps outlined above. By using an Arduino Nano, you gain access to a powerful microcontroller board that can be programmed to accurately control time-based processes. This makes it an ideal tool for creating multi-mode programmable timers that can be used in a wide range of projects, from home automation to industrial automation.
