The ubiquitous LED continues to expand frontiers and applications with a plethora of sizes, colors, and output lumens. Flashing LEDs that incorporate internal electronics for oscillation offer ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, switch a ...

1. Bob Pease used an LM334 current source to servo the current from a PNP transistor through an LED diode. The LM334 will draw current into its V+ pin until the voltage on the R pin reaches 0.068 V.

The circuit shown is a 3-input Resistor-Transistor Logic (RTL) gate. a. Write the truth table for the input combinations of 0V and 5V with respect to the ground. b. Based on the output from the truth ...

Many factors affect the long-term reliability of ceramic-substrate-based chip resistors. Among those are changes in resistance due to soldering, temperature changes, or even the expected shifts in ...

Are you just starting out with soldering and want to practice on a few cheap and easy projects? That’s exactly where I am in my microcontroller journey, and these are the simple projects I did first ...
