Have you ever started a project, run into an issue, started a new project to solve the issue, and completely forgot about the original project? [Andy] went down a rabbit hole of needing a tool to ...

An Atmel AT90S2313 is being used on this frequency counter project along with 3 HC TTL chips and 3-digit 7-segment displays. An Atmel AT90S2313 is being used on this frequency counter project along ...

We all use 74 logic in our projects as general purpose logic interfacing glue. These chips have become as ubiquitous as a general-purpose op-amp, or even as passive components. In most cases we’re not ...

The project is a 4-digit LED voltmeter and frequency counter that was previously based on PIC16C71 but was replaced by 28-pin device PIC16F876. The PIC16F876 is capable of driving 4-digit LED in ...
