<p>Hi!! first of all thanks, it is important to stabblish that this kind of diode has the property of conducing just in one direction, we are using it because we do not want the current to return to the cell, in that case, the cell will work as a resistor, now, the resistance is just helping to disipate power for not damaging the led, so in conclusi&oacute;n, taking in to account a Little bit of voltaje lose because of the nodes we are making with our connections, the output voltaje is of 4.9 volts</p>
<p>This looks great! What is the output voltage going to your phone after you added the resistor and diode? </p>
