Looking for a simple circuit to control the light intensity ... we can use the low voltage output from the Arduino ports to control high voltage/current loads -the popular “12V LED strips”- for ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

and with jumper wires to complete the circuit. If you already uploaded the Blink example to your Arduino, you should see the LED start to blink. Both the LED on the Ardunio and the one on the ...

[Alex] needed a project for his microcomputer circuits class ... it looks like multiple LED’s are lit up simultaneously. [Alex] planned to use an Arduino to control this display, but it ...

Becky Stern shows you how to use digital and analog inputs when building Arduino circuits, including controlling ... turning on an LED, publishing something online. You can tell your board what ...

Last week I explained how to use a motion sensor to trigger an event with an Arduino. The event we triggered was a simple blinking of an LED ... transistor driver circuit for a DC lamp: TO ...
