Sorting Harry’s boxes and I unearthed some useful supplies!

    Current flows from the battery along the negative trace (black) thru a resistor and to the negative lead of the LED. The electrons jump the P-N Junction inside the lens cap emitting light and the depleted current returns to the battery along the positive trace (red). Other blog posts on LED’s LED Close Up  

Charged electrons flow from the power source along the negative trace (green) thru a resistor to the cathode. Like excited lemmings they jump the P-N junction emitting light. Finally, the spent electrons slide along the positive trace (red) to get charged up at the battery.         KEY battery is black negative trace is green resistor is blue […]
