Example projects for Arduino IDE to be used with the ESP8266 System On a Chip
The ESP8266 is an amazing little module, System On a Chip (SOC). I have been using Arduinos in projects for a number of years, some of which have included network interfaces to connect them to the big bad internet. The great thing about the ESP8266 is that is primarily a WiFi Module which just happens to have a powerful, comparably, processor and can be connected to sensors and other applications through its GPIOs.
You can get these modules in a number of flavours including tiny production boards and larger dev boards (NodeMCU) with Lua installed and GPIOs broken out.
After trying Lua and NodeMCU I decided that the Arduino IDE was the way to go :) So here are my projects to get various sensors and examples working on the ESP8266.
All are compiled using Arduino IDE 1.6.7 with the custom ESP8266 board installed and deployed to a NodeMCU dev board.
##Projects BMP085
- BMP085-example-webserver
- Connects to WLAN and starts a webserver on port 80.
- Calls to root URL responds with values from connected BMP085 sensor.
GPS Example
- GPS-example
- Connects to WLAN and start a webserver on port 80
- Connects to GPS using a SoftwareSerial port
- Outputs GPS position to serial console and webserver
- Calls to root URL reposond with current position etc
Real Time Clock Example
- RTC-example
- Connects to WLAN and start a webserver on port 80
- Connects to RTC using I2C
- Respond to queries on the root path with the current time
- Set the time using URL parameters to /set?hour=00&minute=00&second=00&dayofweek=xxxx&monthofyear=xxx&year=16
- Example : http://address/set?hour=21&minute=21&monthofyear=jan&dayofweek=saturday&dayofmonth=30&year=16
