555 Timer IC

The 555 Timer IC is one of the most widely used integrated circuits in electronics. It’s a flexible and reliable timer, pulse generator, and oscillator that can be configured in monostable, astable, and bistable modes.

This IC is perfect for generating delays, PWM signals, frequency generation, or timing control in circuits. It's extensively used in DIY electronics, Arduino-based projects, robotics, and analog signal processing.

The 555 timer operates over a wide voltage range (4.5V–15V) and can source or sink up to 200mA — making it ideal for driving LEDs, buzzers, or even small relays.
