Signal Generator This DIY signal generator can produce sine waves, triangular waves, and square waves with performance. It supports a frequency range from 1 Hz to 1 MHz and offers an adjustable output amplitude for your circuit needs. Five accuracy resolution settings provide coarse and fine tone frequency adjustments, enabling precise control and . Wide power supply compatibility: can be powered by an external 9–12 V DC supply or a 9 V battery, offering flexibility for bench work, field use, or portable setups. Simple installation and debugging: designed with direct insert components, requiring minimal parts and enabling straightforward assembly and easy troubleshooting. Practical applications Use for testing and debugging analog circuits such as filters, amplifiers, and signal conditioning stages, by providing reliable known waveform inputs. Use for validating microcontroller and ADC/DAC performance, by supplying stable sine, triangle, or square wave signals across the 1 Hz to 1 MHz range. Use in education and DIY projects to demonstrate waveform generation, signal types, and practical troubleshooting in a handson learning environment.
