    Description

    The LM358 Duty and Frequency Adjustable Square Wave Signal Generator is a versatile and compact signal generation module designed for various electronics, testing, and automation applications. Built around the reliable LM358 operational amplifier, this module allows users to generate adjustable square wave signals with precise control over both duty cycle and frequency. Its frequency range of 0.07Hz to 200kHz makes it suitable for low-frequency timing signals as well as high-frequency pulse applications. The onboard LED indicator flashes in sync with the output signal, providing easy visual monitoring. Users can select between four frequency levels for fine-tuned adjustment and output customization. Capable of delivering up to 500mA output current through a transistor driver, it can directly power small motors, relays, or external circuits. With simple screw terminal connections, this module is an excellent tool for engineers, students, and hobbyists working with waveform generation, PWM control, and circuit experimentation. Featured By RoboticsBD.
