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
