Im after some basic advice. I have a ds18b20 tempertaure sensor on my arduino mega and what the temperature to print on my 16x2 lcd screen. What do i need to add to my sketch?
So far my sketch for the sensor is
// Data wire is plugged into pin 2 on the Arduino
#define ONE_WIRE_BUS 2
// Setup a oneWire instance to communicate with any OneWire devices
// (not just Maxim/Dallas temperature ICs)
// Pass our oneWire reference to Dallas Temperature.
// start serial port
Serial.println(“Dallas Temperature IC Control Library Demo”);
// Start up the library
// call sensors.requestTemperatures() to issue a global temperature
// request to all devices on the bus
Serial.print(" Requesting temperatures…");
sensors.requestTemperatures(); // Send the command to get temperatures
Serial.print("Temperature for Device 1 is: ");
Serial.print(sensors.getTempCByIndex(0)); // Why “byIndex”?
// You can have more than one IC on the same bus.
// 0 refers to the first IC on the wire
My lcd came on a shield and the pin numbers are 8,9,4,5,6,7
