Tiny Billboard (simple Arduino Project)

The Tiny Billboard : Learn How to display a custom message on LCD with this Arduino Project

Step One : Gathering Supplies

- Arduino board

- LCD Screen (16 pins)

- 10K Ohm Potentiometer

- 220 Ohm resister

- Wires

- Breadboard

Step 2 - Building the Circuit

- Start by connecting 5V to the (+) column next to column J

- Take another wire and connect GND to the (-) column beside J

- Place first PIN of the LCD (corresponding w/ VSS) at A8 - rest of the pins should just go one after the other

- Take a wire and connect ~12 to C11 (which corresponds to RS on the LCD but two over)

- Then, connect ~11 to D13 (which should correspond to E on the LCD but three over)

- Connect ~5 to E18 (connected with in the same row as D4 on the LCD)

- connect 4 to E19 (connected with in the same row as D5 on the LCD)

- connect ~3 E20 (connected with in the same row as D6 on the LCD)

- connect 2 on the arduino to E21 (connected with in the same row as D7 on the LCD)

- Connect a small wire from E22 to F22 and a resistor from I22 to (+)22 (all should be in the same row as A on the LCD

- connect J3 to the second row of the (-) - thus connecting it to GND

- below that small connection, connect J5 to the 5th row under (+)

- place pontentiometer as shown in the photo, side with 2 pins next to the wires on J3 and J5), connect the a wire to F4 to E10)

- connect E8 to the 6th row under (-)

- connect E9 to the 7th row under (+)

- connect E12 to the 10th row under (-). thus connecting to GND

Code

#include <LiquidCrystal.h // this is the library needed for LCD

// initialize the library with the numbers of the interface pins (these numbers are used for the dimensions of the custom message)

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {

// set up the LCD's number of columns and rows:

lcd.begin(16, 2); (these numbers are used for the dimensions of the LCD / where to begin and where to end)

// Print a message to the LCD.

lcd.print("C and M"); // we chose this short message for our's

}

void loop() { //everything listed allows for the message to display continuously

// set the cursor to column 0, line 1

// (note: line 1 is the second row, since counting begins with 0): lcd.setCursor(0, 1); // print the number of seconds since reset: lcd.print(millis()/1000);

}

You're Almost There

- if code does not verify nor upload

- check your wires, make sure everything is connected and placed where they need to be

- make sure your custom message is less than 16 characters
