Hello,
I'm attempting to post a simple message to twitter using an ethernet shield. For some reason the ethernet shield always says the connection is failed and will not connect to the internet to post. I've tried multiple variations of the code and always get the same result. I assume it is something with the IP address or the mac address but I've done research on both. Any help would be amazing. Thanks!
First, see if you can make a get request against a normal http server.
Second, does twitter support unencrypted (http, not https) access? Increasingly the big sites are switching the https-only, but many microcontrollers don't have the ram or flash to do https.
