After purchasing and assembling Jameco's waveform generator (p/n: 2117202, sold separately), I felt that a display of the signal would increase its functionality without having to attach an oscilloscope to read the signal. Wondering why you cannot hear the signal is easier to troubleshoot if you know the signal isn't above human hearing range. This kit will offer a "rough idea" of what signal is being produced. The display will be limited from 250 Hz to 37.5 KHz, for wave forms above 500mV peak to peak. Check out what others are saying about the LCD Display for Waveform Generator project build!
Please note: This project is an add-on and assumes you have built the Function Generator kit (p/n: 2217202). This device cannot be used independently. Due to inventory packaging methods, you may receive more components than required for some products.
