AM-135 NE555 Frequency Adjustable Pulse Generator Module
This module provides a quick and easy way of generating square wave signals using the popular NE555 chip. It can be used in a variety of timer, pulse generation and oscillator applications. The 3 pin header is used for Vcc, ground and output. The potentiometer (variable resistor) is used to adjust the output signal frequency and the duty cycle.
Simply hookup a 5-12 Volt DC supply to the Vcc pin and ground it via the GND pin. The output can be captured at the OUT pin.
For better and more accurate results, we recommend you to adjustment the output signal using an oscilloscope.
