This was last weekend's project. This is my "Binary Box" prototype designed mainly for educational use so kids can learn binary to hex conversion. The circuit consists of (5) on-off switches, a 7404 hex inverter, a TIL311 display, (5) LEDs and (5) 330 ohm resistors. (Power switch hasn't been soldered yet). This circuit runs on +5v. As illustrated, you can see that a lit LED indicates a binary 1 if the switch is turned on. Off represents a binary 0. Images show my son giving the unit its first test run -> 1111 = 15 = F. 1001 = 9
