ESP8266 happiness

It just goes to show that perseverance sometimes pays off. It turns out that the reason I couldn’t get the Olimex esp8266 to work properly was that my USB/serial converter was faulty. The replacement one arrived today, and now I can program the wifi module using the arduino IDE with no problem. Five seconds after programming it, it had connected to my home network and was sending temperature …

More tiny WiFi success

As I have posted before, I have been playing with the super-cheap WI07C WiFi module based on the ESP8266 chip. I’ve now had sufficient success with it that I can publish a post on a working project. This simple setup uses an Arduino nano to read temperatures from to 18BS20 sensors, formats the data as JSON and then sends it over WiFi to a server on my home network. It’s cheap and …

Wifi success, for a change!

I’m actually having success in connecting the super-cheap WI07C wifi module to my home network, so that an arduino can send data anywhere. [caption id=“attachment_373” align=“alignnone” width=“300”] WI07C module featuring esp8266 chipset[/caption] I can now reliably establish a TCP connection and send data back and forth. It works rather well, with some …

WiFi for less than a fiver

Last week, the excellent hackaday ran a story about a new WiFi module (the Wi07c) based on the ESP8266 chip. It is eminently suitable for attaching to an arduino or similar, but it only costs $5. As I’ve been whining for some time about the high cost of WiFi shields for arduino, this piqued my interest. I bought a couple from the electrodragon store and have now had a bit of time to play …
