NE555 Adjustable Square Wave Signal Generator 1Hz - 200kHz
NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator is a 5V square wave signal generator. The 555 timer IC is an integrated circuit widely used in various timer, pulse generation and oscillator applications. This NE555 frequency adjustable pulse generator Module uses NE555 timer IC to generate pulses from approximately 4Hz to 1.3Khz, which can be used for experimental development or driving a stepper motor, it will also be a good choice for users learning and experiencing analog RC.
There are 4 jumpers and 2 variable resistors on the module, users can adjust the output wave with these components to easily get their ideal wave.
NOTE: Please turn off the power before changing the frequency.
