Aside from the Arduino UNO microcontroller, LDR, and the bulb itself, the hardware for this setup is pretty minimal: a relay for the bulb, a resistor for the LDR, and some wires to connect everything ...

An Arduino Pro mini handles the selection between outputs by driving a selection of relays with appropriate timing. An interesting detail here is what [Lajt] calls a ‘sacrificial relay’ in the ...

We’ve seen a great many Arduino synthesizer projects over the ... an FM synth handling wind and horn sections, and a bunch of relays and servos serving as the percussive section.

Today, we are going to explore the TMC2208, a popular driver module used for controlling 2-phase bipolar stepper motors.

This expanded voltage range can make it easier to use only one power source for your entire project, especially if you're working with 24V components like relays, motors, and solenoids.

High voltage relays are electromechanical devices used to switch high voltage (> 1kV) signals. They operate using the same basic principles as electromechanical relays, but include features designed ...

Thermal overload relays are protective devices. They are designed to cut power if the motor draws too much current for an extended period of time. To accomplish this, thermal overload relays contain a ...

The Practical Electronics Crash Course Book and Kit makes entering the world of electronics much easier than many people can ...

The Triathlon Team Mixed Relay format showcases racing at its most thrilling, where the individual sport combines with pure team spirit to produce fireworks on the blue carpet! All four athletes on a ...

The final date on the Penn Relays Summer Showcase Series has gained some notoriety in recent days for its timing and opportunity. The final date on the Penn Relays Summer Showcase Series has ...

The fate of Quincy Wilson was learned late on Sunday night. The 16-year-old has accepted selection into the U.S. relay pool. On Sunday, Quincy Wilson received the phone call he had been waiting for.
