Frequency Adjustable Pulse Generator Module NE555
This module is a square wave signal generator based on the NE555 timer IC. It allows for adjustment of both pulse frequency and duty cycle, although these parameters are interdependent. The output signal is a single channel with an approximate duty ratio of 50%.
The module can generate pulse frequencies ranging from about 4Hz to 1.3kHz, depending on the frequency adjustment knob setting. It features a power indicator LED and operates the NE555 timer IC in astable mode, making it suitable for applications like stepper motor control and testing.
The NE555 timer IC is a versatile component used for various timing, pulse generation, and oscillator functions. It can function as a timer, oscillator, or flip-flop, and comes in multiple variants that can offer up to four timing circuits in one package. Introduced by Signetics in 1971, it remains popular due to its simplicity, low cost, and reliability, available in both bipolar and low-power CMOS versions.
This module is perfect for producing square wave signals for experimental development or motor driving, and it provides adjustable pulses for microcontrollers and other pulse-controlled circuits.
