Simple logic probe with resistors,transistors, and LEDs. The pin on the left side is for a probe which could just be a right-angle header pin. The right side is for a screw terminal for hooking in alligator clips,banana clips, etc. The transistors I used are 2N3906 for Q1, and 2N2906 for Q2. One LED indicates logic high, and the other indicates logic low.
