For those of us who remember LED calculators, the HP 5082-7400 series red “bubble” displays hold a special charm. Available in 3, 4, or 5-digit varieties, these multiplexed 7-segment displays ...

For example, Arduino Pin 4 is on PD4 (PortD pin 4). Arduino Pin 11 is in reality PORTB Pin3 (PB3) on the ATMega 328 Microcontroller. Figure 1 shows to which Pins on the Arduino Board the 74LS47 ...

The 4-bit to decimal or hexadecimal decoders are well-known and easy to use, but when the binary word has more than 4 bits the decoding gets difficult, especially when decoding binary-to-decimal. This ...
