555 Timer IC
The 555 timer IC is a versatile integrated circuit used for generating time delays, pulses, and oscillations in electronic circuits. It is a popular and inexpensive component that can operate in three main modes: astable (oscillator), monostable (one-shot), and bistable (flip-flop). Its 8 pins include a power supply (VCC), ground (GND), trigger (TRIG), output (OUT), reset (RESET), control voltage (CTRL), threshold (THR), and discharge (DIS).

74HC595 Shift Register
The 74HC595 is an 8-bit serial-in, parallel-out (SIPO) shift register that expands the number of outputs available from a microcontroller. It uses serial data input to fill its internal shift register and then presents all 8 bits simultaneously on its parallel output pins by transferring them to a separate storage register. This allows you to control multiple outputs, like LEDs, using only a few microcontroller pins.

ULN2003 Driver IC
The ULN2003 is a high-voltage, high-current driver IC that contains seven NPN Darlington transistor arrays. It’s designed to amplify low-current digital logic signals to drive loads like stepper motors, relays, solenoids, and high-current LEDs. Key features include common-cathode flyback diodes for inductive loads, a 50V output voltage rating, and a 500mA collector current per channel. Its inputs are compatible with TTL and 5V CMOS logic, making it easy to interface directly with microcontrollers.
