Read analog values without an ADC using PIC12F675 microcontroller

Digital electronics and Analog electronics doesn’t mix easily. A Microcontroller can’t get analog values unless an Analog-to-Digital converter is used, however, you may find a little complicated the use of an ADC and it need lots of Input/Output ports.   Some Microcontrollers, like the small 8-pin Microchip PIC 12F675, do have an ADC integrated, but …

EEG Error Correction Interface

Introduction Our project was an EEG-controlled brain computer interface that allowed a user to correct errors in machine behavior. The project was modeled as a trial-based “game.” In each trial, a solid colored green block or dotted yellow block was placed on a conveyor belt. One end of the conveyor belt had a solid colored …
