Intro: ARDUINO UNO WITH 16x2 LCD DISPLAY
Hi everybody's... Here i show you how to simply programming custom character on 16x2 LCD display using arduino uno and android smartphone. You can display your own words simply.
Step 1: SOFTWARE
Here I used to programme MCU atmega328P (which is on arduino uno board) "ArduinoDroid" by Anton Smirnov . this IDE you can download from Google playstore.Open IDE go to options select "sketches" select "libraries" select"liquid crystal" select examples,open "hello world.ino" save as to another name, because you can't edit original sketch. Open saved skech file then change program line "hellow world" to"your own name".go to option menu select actions compile, after compiling ready to upload arduino board.
Step 2: HARDWARE
I assembled this display using solderless breadboard . this project need
3, jumper wire
4, 1k resistor
5, USB ,OTG cables
6,LCD 16X2 display
Step 3: CIRCUIT
The circuit also described hello world programme. Connect header pin wires as shown in the image, this circuit didn't use separate power supply .power supply from the smart phone by OTG cable.
Step 4: UPLOADING SKETCH
Edited sketch file after compilation upload to arduino ,Option menu select actions and upload or use short cut button .see photographs below..thanks...
