Send characters and commands to an LCD display and watch your changes in real-time. No more needing to flash an Arduino Sketch every time you would like to test a simple change!
Ideal for beginners who are learning about LCD programming, LCD program planning, or just some all-round good fun for anyone.

Currently only works with a compatible 16x2 LCD module but I hope to add 16x4 and 20x4 modules in the near future as well as the I2C adapter.

In order to use this app correctly, you will require the Arduino companion sketch available on the website at: https://installtekz.com/ArduinoLCD

This app along with it's companion sketch utilizes the Arduino 'LiquidCrystal' library.



Functionality:
*Send text strings
*Create your very own custom characters and save/delete them in the app
*Includes preset characters such as smiley, battery status, heart, arrows etc.
*Send commands include changing column/row cursor position, clear screen, show/hide block/underline cursor, switch display on/off
*Sketch code snippets
*Moving characters left/right across the display
*Auto scroll characters
*output direction left-to-right, and right-to-left

Language Translation Notes:
*This app has been translated into multiple languages using a translation tool and for this reason I apologize for any translation inaccuracies. If you feel the urge to send me details highlighting a translation that you think should be changed then please feel free to send it to me via email at: installtekz@gmail.com

*Although I have translated everything in the app its self, I have not tested this app thoroughly enough using various Android language keyboards with the LCD as there may be character issues. ## Similar extensions and apps - [LCD Controller](https://chrome-stats.com/d/ioio.LCDController) — 2,116 users - [Arduino bluetooth lab](https://chrome-stats.com/d/com.minervalink.arduinobluetoothlab) — 727 users - [LCD Display Character](https://chrome-stats.com/d/com.iAKIN.lcdcharactergenerator) — 2,421 users - [ArduinoBlue](https://chrome-stats.com/d/com.snappyxo.mobileapp) — 6,068 users - [BlueDisplay](https://chrome-stats.com/d/de.joachimsmeyer.android.bluedisplay) — 2,231 users - [Arduino Lamp Controller](https://chrome-stats.com/d/com.blogspot.ardulathtech.projectone.releaseAlpha) — 1,619 users - [ScreenArduino](https://chrome-stats.com/d/com.p.screenarduino) — 8 users - [Arduino bluetooth controller](https://chrome-stats.com/d/com.giumig.apps.bluetoothserialmonitor) — 1,160,383 users, 3.79 / 5 - [Arduino Bluetooth Controller](https://chrome-stats.com/d/com.appsvalley.bluetooth.arduinocontroller) — 315,869 users, 2.79 / 5 - [Arduino Multiple Controller](https://chrome-stats.com/d/appinventor.ai_sivarajan931.Project_Immortal) — 1,274 users - [EduConnect - Arduino bluetooth](https://chrome-stats.com/d/com.eduboticsperu.educonnect) — 22,850 users - [Bluetooth Electronics](https://chrome-stats.com/d/com.keuwl.arduinobluetooth) — 2,008,093 users, 4.08 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.installtekz.ArduinoLCDplayground)
