This NE555 Pulse Frequency Duty Cycle Adjustable Module is a versatile signal generator built around the renowned NE555 timer IC. It provides a user-friendly platform for generating stable square wave signals with fully customizable frequency and duty cycle. The module includes two potentiometers: one for adjusting the frequency (Hz) of the output waveform and another for fine-tuning the duty cycle (the percentage of time the signal is “high” versus “low”). With a wide operating voltage range (typically 5V-15V DC), it integrates easily into various electronic projects, such as controlling the speed of DC motors via PWM, dimming LEDs, creating audio tones for buzzers, or serving as a clock source for digital circuits. Its compact design and straightforward interface make it an essential tool for hobbyists, educators, and engineers prototyping or testing systems requiring precise pulse signals.
