This folder contains some sketches used with the Arduino to achieve certain functions.
The 20mA Konverter sketch translates a 20mA current loop power equivalent of a current clamp to an S0 compliant impulse used to monitor the output of a wind turbine. In its default configuration 1 impulse is generated per 50 Wh. Also a non-zero offset power is subtracted (reactive power); note that these settings have to correspond to the actual type of current loop used (0-20mA vs 4-20mA for full range).
The Uno NTP ENC28J60 sketch sends Network Time Protocol packages to a
time server and receives the corresponding time packages via UDP; time
is output to the serial connection. It uses Norbert Truchsess' Arduino UIP ENC28J60 library.
This sketch works with an Arduino Uno and attached ENC28J60 module. For use with an Arduino Leonardo the Slave Select assignment has to be changed in the library file Enc28J60Network.h.
In memory of John Horton Conway this sketch implements (yet another time) the Game of Life on an Arduino (Mini Pro) with attached MAX7219 controlled LED matrix.
As an example for having an alternative display on an IKEA Obegränsad LED lamp this is the Arduino preparation to display the classic Mandelbrot Set, the "Apfelmännchen".
Using the year end vacation to "finally" get something useful on the IKEA Obegränsad LED lamp, I implemented a temperature, relative humidity and iconized pressure display, using an Arduino Mini with an BMP280 environment sensor. It works, when the mapping is right :-) For more information, refer to the code in the Envi_Obegraensad folder.
