I’ve been spending a lot of time thinking about op amps and comparators lately. One of the common uses of an op amp is as a “unity gain” buffer, meaning that the output voltage is as close as possible to being the same as the input voltage. At a glance this might seem like a […]

The reference voltage plays a very important role in any A/D conversion. It determines both the range and the resolution (Volt/Count) of the A/D conversion. Besides, the accuracy of the conversion also depends upon how stable the reference voltage is. Usually in PIC microcontrollers, the reference voltage for A/D conversion can be selected as the
This is one project that i’m doing, now I’m going to show how to do it only for one motor, but i’m using and DEMUX to in the future use 4 motor. The project is simple, it uses the pic to control the DEMUX and the DEMUX control the H-BRIDGE that control the motor forward
