Arduino 6: TKPhotovoltaic Sensor, Use of Serial Monitor, Sensor Range Mapping
By suggestion, I hooked a simple PV cell to the potpin sensor input, and recalibrated the sensor range using values read off of the Serial Monitor tool in the Arduino IDE. I show how to use the SM to see the raw sensor values, then I show where in the program sketch to set these values so that the LEDs map the whole range of interest. –Sorry about the light! I hope the screen comes through the encoding all right. Program sketch can be downloaded here: www.mediafire.com And the basic circuit and layout is explained in the first of this series dealing with the voltage measuring potentiometer sketch. Thanks for watching!
