Brilliant. And finally, the free-form night light circuits are great. Fine-tuned to draw the minimum current, they’re adjusted to the specific LEDs and phototransistors that [Smerfj] had on hand.

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s ...

Toshiba Electronics Europe has introduced the TB67S559FTG 50V/3.0A stepper motor driver IC that supports constant current control with built-in current detection. 50V/3.0A constant current stepper ...
