Show us what you see in the Serial monitor. There is no problem with compatibility with sketches of that age and IDE v1.05 Cheers ! Geoff Serial Monitor showed; DHT output: 22.40 After rounding: 22.00 finalString: DHT output: 22.40 After rounding: 22.00 finalString: DHT output: 22.30 After rounding...

Who created a code temp but date was last April or more past which used Arduino version is 1.0.4 by March 11th 2013, but now 1.0.5 by May 15th 2013, and might not work with this code I have tried so nothing, maybe 1.0.5 not work for this code, anyone have try with code use 1.0.5?

I have tested with code who created, but huge problem! I checked read temp without createTextTemp(); read temp is fine by Serial Monitor. And removed all like; if (t==-8.50) { finalString=finalString+"-8.5 "; } I made short code for test only; void createTextTemp(){ finalString=" "; // wipe the sent...

The output from the debugging serial prints shows the sensor reading is working fine. Your issue is with the code that converts the value to a string, likely in createTextTemp() therefore. Yeah, something with createTextTemp() that problem, no idea, haven't solved problem for ages, I will try fix w...

Hi, yeah I think to understand, I added code from yours, serial monitor show funny something this; DHT oRea¤DHT oRea¤DHT ouReadDHT ouReadDHT ou So I removed createTextTemp(), then running its working show monitor this; DHT output: 22.40 After rounding: 22.00 finalString: DHT output: 22.40 After rou...

I changed code for test only, example I picked few code, only show this; String finalString="test"; void loop() { // get the temperature and round it to nearest 5 t=dht.readTemperature(); t=round5(t); //now create the text to display on the DMD //createTextTemp(); // now send the text to the DMD dra...

Steyker, really, am I very near having that thing solved for DS18B20? I will still try doing, but I bought DHT temp, I copied your code for DHT, I played up and then still nothing screen, but found out not because of Dallas or DHT, because same happened DMD nothing running but start with finalString...

All right, I'm still trying figure out, if still no good so give up then better buy DHT HUMID: Humidity and Temperature Sensor Module. simple way as most work.
Thanks.
