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 infrared LED ...
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 ...
Example: circuit determines the LED has a forward voltage of 1.8v and you have 99v, 10mA set, it will do this: 99v-1.8v/0.01A and come up with 9720 ohms resistor. (10k would be the nearest common ...
To calculate the resistance of the series resistor required, we need to look at the current and voltage values recommended by the LED manufacturer. Suppose a manufacturer recommends a maximum ...
In production, this may be replaced with a zero Ohm resistor. The open circuit protection circuit shown utilizes R9, causing it to serve an additional function, in conjunction with Zener diode D2. In ...
