To provide power to the 74HC595 shift register, we give +5V to VCCand we connect GND to ground on the arduino microcontroller. When connecting shift registers to microcontrollers, the serial data input line (pin 14) gets connected to digital pin 11 on the arduino. Through this connection, th...
PL2303HX— USB<>RS232 converter, chips like this are used in Arduino-like boards for example: LM1117— low-dropout linear regulator: 74HC595— 8-bit shift register: NXP 74AHC00— quad 2-input NAND gate. This is a nice example that 'old' tech nodes (1µm and older) are still in u...
