+# Overview
+
+This is an Arduino sketch for an ESP8266 module connected to an AD8232 ECG sensor module. It uses the ADC to sample the data and writes it as a continuous stream to a computer that is running a FieldTrip buffer.
+
+You can use the webinterface to set the IP address and port of the receiving computer.

 ## SPIFFS for static files
 
 You should not only write the firmware to the ESP8266 module, but also the static content for the web interface. The html, css and javascript files located in the data directory should be written to the SPIFS filesystem on the ESP8266. See for example http://esp8266.github.io/Arduino/versions/2.0.0/doc/filesystem.html and https://www.instructables.com/id/Using-ESP8266-SPIFFS for instructions.

 # Overview
 
-Updating the firmware on the Wemos D1 mini board using the Arduino IDE requires that you install the drivers from https://www.wemos.cc/downloads.
+This is an Arduino sketch for an ESP8266 module connected to a neopixel LED strip. It uses ArtNet to control features of the light pattern, such as the brightness and the speed. There are a number of modes implemented to make nice patterns, such as a slider that moves from one to the other side.
 
-The Neopixel and Art-Net settings can be updated on the fly like this
+## Webinterface
 
-curl -X PUT -d '{"universe":1,"offset":0,"pixels":24,"leds":4,"white":0,"brightness":100,"hsv":0,"mode":10,"speed":8,"split":1,"reverse":0}' artnet.local/json
