| Sep 24, 2014 at 13:09 | comment | added | tcrosley | @RobertAtkins Understand, I do both hardware and firmware myself (have degrees in both). Trimpots connected to ADCs would qualify as a user interface. Since in your question you said you were looking for a schematic, I assumed you were just interested in a hardware solution. Perhaps my circuit will be useful to someone else in the future. | |
| Sep 24, 2014 at 10:40 | comment | added | Robert Atkins | I could also add trimpots on the analog pins of the Teensy :-). But I'm historically a software guy so that's the hammer I'm going to use. Thanks again. | |
| Sep 24, 2014 at 10:32 | comment | added | tcrosley | @RobertAtkins A microcontroller would work just fine for this. Although the schematic looks complex, it is actually a pretty small circuit comprising just two 14-pin ICs and some resistors and caps -- pretty simple to build on a perfboard in an hour or so. The advantage of the circuit, is using trimpots you can easily adjust the timing whereas with the program you would have to change the values in code and then reprogram the micro (assuming you don't have a user interface). | |
