Learn how to test and debug relay logic circuits for electrical controls with this guide. Follow six steps to check inputs, outputs, logic, scenarios, and documentation.

Logic testers are simple but very helpful devices in testing digital circuits. A logic probe can be designed in many different ways. In this particular design, a combination of discrete and TTL logic ...

Learn how to use a logic probe to check the operation of digital circuits and troubleshoot some common faults. This article explains what a logic probe is, how to use it, and how to avoid errors.

Even if you have an upmarket logic analyzer and are completely at ease with its operation, you are unlikely to use it to debug simple circuits like Arduino and Raspberry Pi add-on boards. That’s where ...

The design of a simple logic tester producing audio outputs is described. These audio outputs are distinct frequencies, approximately an octave apart, and correspond to the logic states '0,' '1,' and ...

Snap-on says its new 6-Volt and 12-Volt Circuit Tester Series (EECT300HG,O,R) is designed to be a time saver and productivity enhancer for service technicians. With its patented Instinct handle and ...

Light logic doesn’t use the conventional active devices you’d expect such as transistors, tubes, or even relays. Instead, it uses LEDs and CdS cells to make rudimentary switches.

There's a long wish list for a workable quantum computer: a viable system must be fast, compact and stable. The first integrated optical quantum logic circuits are a step in the right direction.

Beep - a sounding logic probe/tester [140410] I find it pretty annoying when I use a multimeter and look at the display only to find out that I accidently disconnected the probe from the pad.That's ...
