AP Biology Investigation #1 - Artificial Selection Chemistry LED-indicating 2-input OR gate module

LED-indicating 2-input OR gate module showing HI and LO states with red and green LEDs and a printed truth table on the board

this bare Eureka constantan wire takes advantage of the alloy's low temperature coefficient

and the relationship of pH scale to acid and base strength

Built for home apothecary and herbal preparation

For benchtop and field water quality testing
