I am using an Arduino Uno R3 and RGB positive LCD (adafruit ID 398).
Following examples and tutorials both work, but I am struggling to get the Arduino Analog Read Voltage example (http://arduino.cc/en/Tutorial/ReadAnalogVoltage) to display on the RGB LCD.
I've played around with this for several hours and am embarrassed to admit I'm obviously confused!
Can you help with the simplest method of displaying this on the LCD rather than serial monitor?
The basic code is:
Code: Select all
/*
ReadAnalogVoltage
Reads an analog input on pin 0, converts it to voltage, and prints the result to the serial monitor.
Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.
This example code is in the public domain.

// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(A0);
// Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V):
float voltage = sensorValue * (5.0 / 1023.0);
// print out the value you read:
Serial.println(voltage);
}
