Here’s how it works. Jay Holben During one of my recent lectures, there was a great deal of confusion about how to adjust light intensity and when does light quality and/or color change when altering ...

Changes in tree-ring density in the Arctic may be evidence of changes in light intensity during the trees ... the emails from the Climatic Research Unit at the University of East Anglia, where ...

Increasing the incident-light intensity more quickly discharges the capacitor, and lower light levels decrease the discharge rate. The microcontroller, an Atmel AVR ATtiny15, measures the time for Pin ...
