This project is an ON/OFF flip flop switch circuit built around the popular NE555 timer IC. It acts as a latching switch: pressing a button once turns the output ON, and pressing it again turns it OFF.

Features:

• Uses a single NE555 timer in a bistable configuration.
• Simple design with minimal components.
• Works with push button input.
• Provides a stable ON/OFF toggle output.
• Can control LEDs, small relays, or logic-level circuits.

Why to use it?

• The NE555 is one of the most versatile ICs in electronics. In this design, it makes a reliable toggle switch without the need for microcontrollers. It’s perfect for learning, prototyping, or practical use in DIY electronics.

Applications:

• LED and lamp control
• Relay and motor switching
• Logic signal toggling
• Educational projects with NE555

All essential project files are included: schematic, layout, BOM, Gerber files, and assembly details, making it easy to build and test.
