NE555 Adjustable Pulse Frequency Duty Cycle Square Wave Signal Generator

NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator is 5 V square wave signal generator. It generates a square wave signal used for experimental development. Also, use to drive a stepper motor for generating a square wave drive signal. The output duty cycle can fine-tune. Duty cycle and frequency is not separately adjustable, adjusting the duty cycle will change the frequency.

The NE555 timer is a popular and easy to use for general purpose timing applications from 10 µs to hours or from <1mHz to 100 kHz. In the time-delay or mono-stable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the a-stable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. Maximum output sink and discharge sink current is greater for higher VCC and less for lower VCC.
