| − | The foundation for Xeno Fusion is based upon basic LED connectivity.<br>
| |
| − | The diagram in figure 1 shows an LED connected to an Atmega8 (XenoGC) at pin PD5 and GND. Current flows from the anode to the cathode and a resistor is used for current limiting protection. Atmega provides up to 40mA output per pin. <br>

| − | Atmega8L (XenoGC) operates at 3.3v. <br>
| |
| − | If an LED is rated at 2.0v forward voltage with up to 20mA forward current, then a current-limiting resistor value of 220ohms will provide 5.9mA of operational current which is under the 20mA of forward current allowing safe operation of the LED. Also the current-limiting resistor creates a 1.3v voltage drop. <br><br>
| |
| − | current = (( supply voltage - forward voltage ) / resistor value ) * 1000 <br>
| |
| − | current = (( 3.3v - 2v ) / 220 ohm) * 1000 <br>
| |
| − | current = (( 1.3v ) / 220ohm) * 1000 <br>
| |
| − | current = (( 0.0059 ) * 1000 <br>
| |
| − | current = 5.9 mA <br>
| |

| − | voltage drop = resistance * current<br>
| |
| − | voltage drop = 220ohm * 5.9 mA <br>
| |
