Modern Logic Probe was designed to measure 0´s and 1´s logics and for working with a voltage from 5V to 12VDC. This project was based in an LM358 and a common cathode RG LED to its monitorial. The Modern Logic Probe is capable of being adjusted to 0V with help of a couple of trimmers of 5K for turning off the RG LED. Using the project, the result is a RED led turns on when a ´zero logic´ is applied or a Green LED turns on when an ´one logic´ is applied.
