floresta:
That's all I'm using.
No it's not - there's data on the LCD screen.
For each thing you try we need to see the entire sketch and a photograph of the resulting display.
Don
That is all I'm using. I said I wrote to the LCD just as a quick test. Then I rem'd the lines out because my most basic problem is that I'm not getting data to the shield. But here is the entire sketch:
// Example testing sketch for various DHT humidity/temperature sensors
// Written by ladyada, public domain
//#include <LiquidCrystal.h>
int sensePin = 2;
#include "DHT.h"
//LiquidCrystal lcd(8, 9, 4, 5, 6, 7);
// Uncomment whatever type you're using!
#define DHTTYPE DHT11 // DHT 11
//#define DHTTYPE DHT22 // DHT 22 (AM2302)
//#define DHTTYPE DHT21 // DHT 21 (AM2301)
// Connect pin 1 (on the left) of the sensor to +5V
// Connect pin 2 of the sensor to whatever your DHTPIN is
// Connect pin 4 (on the right) of the sensor to GROUND
// Connect a 10K resistor from pin 2 (data) to pin 1 (power) of the sensor
DHT dht(sensePin, DHTTYPE);
void setup() {
Serial.begin(9600);
Serial.println("DHTxx test!");
dht.begin();
}
void loop() {
// Reading temperature or humidity takes about 250 milliseconds!
// Sensor readings may also be up to 2 seconds 'old' (its a very slow sensor)
float h = dht.readHumidity();
float t = dht.readTemperature();
//float temp = t * 9/5 + 32; //Convert *C to *F.
Serial.print("Humidity: ");
Serial.print(h);
Serial.print(" %\t");
Serial.print("Temperature: ");
Serial.print(t);
Serial.println(" *C");
}
Here are my results plugged up directly to the arduino:
Using the same sketch with the shield on here are the results:
So I think I've read the pinout on the shield wrong or something. I can't figure out what pin will pull data to the shield.
