Tachometry, the measurement of the speed of spin of rotating objects, is a common application. Some of those objects, however, have quirky aspects that make them extra interesting, even scary. One ...
Through light waves, optocouplers transfer signals of all types between components. Due to their mode of operation, they also provide electrical isolation and noise immunity not found in other ...
We have stumbled upon another limited-edition timepiece for you Honda fanboys. Yes, you, too, lover of quirky car-related watches. Unlike the vintage S2000-shaped analog gold watch, though, this one ...
If you're developing a wrist watch, a small light-following robot, or a portable weather station with Arduino, one of the best boards you can use is the Nano, and for good reason. It's pretty compact, ...
Learning electronics? Then, chances are you already know what an Arduino is, or at the very least, you've heard of it. After all, it's among the most popular electronics platforms available in the ...
Würth Elektronik has released a detailed and thoughtful app note on using opto-couplers, particularly ‘817’ types. AN0007a* ‘Understanding phototransistor optocouplers’ goes deep into analogue and ...
This simple scheme is based on the circuit shown below (Figure 1) in my recent article [1]. Figure 1 Using common transistor optocoupler to achieve a tube-like sound. It is known that the main feature ...
Utilizing the photo-sensitive nature of silicon, VMI has created a line of hermetically sealed, high voltage optocouplers and opto-diodes in versions that can be assembled in series configuration for ...
