Signal Relays Explained

Most people with some basic knowledge of electronics are familiar with relays. These electronically controllable mechanical switches are likely to be found where ever AC power is remotely switched, and are also common in many DC systems like your car. Their distinctive “clicking” is what we expect when turning the thermostat knob towards red or, […]

Power Relays vs. MOSFETs for Microcontrollers

When you want to switch high currents or voltages with an Arduino or similar microcontroller, relays and MOSFETS are likely to be your top component choices for doing the actual switching. Both types of components are available with voltage and current ratings in hundreds of volts and amps, and, when properly implemented, can do a […]

MOSFETs for Arduino

Power MOSFETs are a great companion to Arduino and similar microcontrollers when it comes to controlling pumps, motors, heaters or other high-power devices. These transistors allow you to use a weak digital signal from the microcontroller to switch high voltages and currents that many power-hungry devices need to operate, but that the controller itself cannot […]

ESD Tools Explained

Electrostatic discharge (ESD) may be a minor nuisance in everyday life, but in working with sensitive electronics, it is a veritable hazard. One of the many methods of combating the destructive effects of ESD at electronics workstations or assembly lines is the use of ESD or “anti-static” hand tools. Being practically identical in appearance and […]
