Here’s the simplest BJT LED Driver circuit. ... You can drive your MOSFET gate from 12 V, just add another driver transistor between MOSFET and Arduino. You will get much lower Rds(on) ...

This is a very simple arduino project where a led is turned on by setting the pin 13 as output, then write it with a high value, in our case that means that pin 13 will deliver 5 volts. Advertisement ...

One is to include a power LED driver circuit to handle husky LEDs or LED strings/strips. And of course, you’ll need to build an 8-channel LED driver circuit. Look at the single-channel (1/8) LED ...

Arraying LEDs and picking a driver IC. For this example design, 100 LEDs will be used and each dissipates 1W. An intermediate DC bus of 48V is a good choice because off-the-shelf AC-DC power supplies ...

An LED-driver reference design for an LED replacement of 100W incandescent bulbs has been introduced by Power Integrations, writes Richard WIlson. Dubbed DER-322, the circuit is desigend to fit neat ...

You could put the Arduino in deep sleep, if you wanted to and that LED will still blink. With a little work, you could probably adapt this idea to any number of circuits out of the 555 playbook ...

A team of software engineers and designers released Arduino in 2005 as a teaching tool for graduate students in interactive design, but it quickly caught on in the DIY community.
