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 ...

The completed circuit should look like Figure 2. Figure 2. Circuit for a Single LED Blink Next, in your Arduino IDE, open the sketch in Examples→Basics→Blink, which should look like Listing 1. Listing ...

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 ...

Let it hit your red LED and you’ve lost a point ... Inside the cool laser-cut box is an Arduino Uno and a 9V battery, plus a current-limiting resistor and the all-important buzzer.

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 ...

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 ...

it does pack expert-led instruction on how to make various things with Arduino. With lessons taught by actual engineers, you’ll learn how to make your own Arduino circuit with various hardware ...
