Detail about 555 Base Frequency Adjustable Oscillation Module

This little module is based on the ever-useful 555 timer IC. It features adjustable frequency over 4 separate ranges and you can also vary the duty cycle. This is ideal for producing timer and clock signals, of for flashing LEDs, or anywhere you would use a 555 timer in astable (oscillator) mode. The 555 timer IC is an integrated circuit used in a variety of timer, pulse generation, and oscillator applications. It can be used to provide time delays, as an oscillator, and as a flip-flop element. This NE555 frequency adjustable pulse generator Module utilizes the popular NE555 timer IC to generate pulses from about 4Hz to 1.3Khz, which can be used for experimental development, or driving a stepper motor, it would be also a good choice for learning & experiencing the analog RC circuits.
