This paper presents a new design of a 2 to 4 decoder constructed using 3-transistor NAND gates, contrasting it with the conventional 4 transistor NAND gate-based technique. The primary aim of this ...

He first built a breadboard decoder circuit that would light 1 of 16 LEDs depending on the detected button press. This was well and good, but he decided that an Arduino-driven LCD display would ...
