JX Wave Generator

Use Arduino, an OLED display and an AD9833 DDS module to create a useful wave generator for your lab.

For a long time I have put off buying an oscilloscope. Now, after purchasing it, it’s time to also have an inexpensive signal generator for hobby use, essential for diagnosing audio circuits and more. Combining the two passions for electronics and computing, the best thing is to do it yourself with Arduino.

- Output frequency between 1 Hz and 999999 Hz
- two modes of frequency variation: logarithmic and single digit
- three types of wave, sine, triangular and square
- AC or DC output coupling
- ability to sweep continuosly between two predefined frequency values
- controlled exclusively by a single knob
- integrated screen saver to preserve the life of the oled display”
