Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels to fulfil your requirements! Just follow the schematic diagram to complete the construction, and use any ...

To regulate the brightness level of an LED with PWM, just connect it to one of the PWM channels (with a 1K resistor in series) and use the “analogWrite” command to control the duty cycle, as shown in ...

Olympia Circuits Teases Arduino Programmers With $60 Arno Shield. by Ray Willington — Monday, April 29, 2013, 05:50 PM EDT. Comments. Homemade gadgets seem ... - One RGB LED - One infrared LED ...

Put your LED in the collector circuit and connect anode to your PWM signal. (Easier to describe with a sketch, but I think I have it). The emitter of the transistor is 5-0.7V, so about 4.3V this means ...

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is ...

Olympia, WA, April 29, 2013– Olympia Circuits introduces the Arno Shield to expand their line of products for new Arduino users. The Arno Shield contains all the components necessary to learn ...
