Many microcontroller designs typically mix multiple interfacing methods. A microcontroller (µC) system can be viewed as a system that reads from inputs, performs processing and writes to outputs.

A simple and convenient way to interface 2 relays for switching application in your project. This relay driver boosts the input impedance with a regular BC547 NPN transistor (or equivalent). Very ...

Our Radio World colleague Charles S. “Buc” Fitch, P.E., recently completed a relay interface assembly for controlling an older auxiliary transmitter. Late-model transmitters have remote control ...

Serial Peripheral Interface (SPI) output driver chips are popular with embedded designers because they provide multiple outputs without using any CPU I/O pins. This article explains how to adapt a ...

MicroMax’s M-Max 400 RC is a highly reliable computer for building all-electric interlocking distributed systems. The system converts CAN-interface control signals (twisted pair or single-mode fiber) ...

When it comes to electronics, it seems like a relay is such a simple device – yet, it is able to interface some pretty elaborate high-end systems with a fire alarm system. Working with relays is an ...
