In LEDs heat and high currents hasten the dimming process which can lead to unreliable operation in LED-powered optocouplers. Some simple and straight-forward analysis will keep their light shining ...

Optocouplers are used extensively for high-voltage isolation and electrical noise rejection – two essential requirements for transmitting correct information between different voltage potentials ...

The build produces a color sensor using an RGB LED and a CdS photocell by retrieving color using Arduino. The build produces a color sensor using an RGB LED and a CdS photocell by retrieving color ...

Deep in the heart of your latest project lies a little silicon brain. Much like the brain inside your own bone-plated noggin, your microcontroller needs protection from the outside world from time to ...

Designers of switch-mode power supplies generally put a lot of care into selecting the placement of poles/zeros of the supply transfer function to ensure stable operation. However, many such designs ...
