DAC Version 2

A single analog to digital converter using resistors, a 4-bit counter (as digital data generator) and an operational amplifier.
I put a presentation interface for easy monitoring of data (digital) and a lamp to monitor the analog output (for brightness).
In this version also replace the virtual component "logic train" by an oscillator based on two NAND gates (which I was demonstrated in http://everycircuit.com/circuit/5531866909638656), thus making the motagem entirely feasible circuit.

Still, following the generous tip @hurz, reversed the order of the resistors and this became the most ordered analog sequence. Thanks Hurz

Your opamp is upside down

@abobaker is right, for a real implementation you have to swap plus and minus input terminal of the opamp to get an inverting amplifier. Good to see you have a lot of fun with electronic! Keep it up! http://everycircuit.com/circuit/5204921816711168

Oh, yeah, Hurz and abobaker!!!! I´m fix the OpAmp position. Thanks guys!

Why do you say dac if it's an analog to digital... also this isn't converting anything to analog it's just generating the wave itself. Though I do like the concept on a whole
