DAC using R-2R and aceletometer electro bike aplication

[pabsironman]

Hi,

Here is one proyect I made for CORPAIRE (Quito) for an aplication in a electro bike, I am using a 4 bits DAC using the method R-2R, i am aware this will be done with some IC as DAC4008 and other but they need special ajustments with capacitors and negative sources. There are diferents modules which I used for a display box with one switching button and a reset button for the distance. Any question? just ask... The DAC controls a driver for DCBM.
