Hi there,
i have recently been trying to get a dht22 temp sensor to collect and push its information to a freeboard.io via dweet.io

i found a sample code (thats all i can really do at this level of knowledge is use sample codes) and uploaded that but i found that the board would not process the code past a certain a point and just restart the code. anyway so after some playing around i managed to get to get more code to be processed, i will post the sample code and i will also post my altered version of it, please help.

Your code does something. Seems that you forgot to tell us what it actually does. Seems like you forgot to read the stickies at the top of the forum that show you how to post code properly, too.
