Project 0

Sometimes very small project can be useful. This is one of the smallest projects made with two led preferable with different color.
Playing with a low current, low current circuit i wanted to add some leds.  To simply check the signals and deciding how to add the leds I soldered two leds in opposite direction. By using two different color leds (red and yellow) immediate see the polarity even from a distance or in the dark during the test phase of the circuit. This as leds are polarity sensitive.
It is possible to add a resistor, however for a temporary test in a low power low current circuit this is not needed.
