#104164 - 0-10 V output |
Hi forum!
I must do a litle device, that read some pushbuttons, and return a DC voltage betwen 0 and 10V. It shall replace a potemtiometer, that is used to control lightningbrightnes. It could be done using a micro and dac or a micro and a digital pot. It could also be done with a micro, some software PWM, a filter and a op-amp. I would prefer using a AT89C2051 and do a device reading 8 pushbuttons (4 for "up" and 4 for "down")having 4 0-10V outputs. As simple as possible! Resolution isnt critical - 10 steps or so betwen 1 and 10 V out should be sufficient. Any comment apreaciated Go' weekend Per |
