INDEX

The following figure shows the normal diode available in the market.

Above figure shows how to bend the leads of a diode and a resistor so that a properly inserted into breadboard or PCB. But remember not to bend too close to body.But there are different diodes-LED,IRLED,Photo Diode,Zener Diode. But in robotics we use LED,IR LED's , Photo Diodes. Diode and Zener diodes are used, but rarely.

Can u tell the voltage,v . Vcc ranges from 0-50(it can go up to 200v also, for high power ). v range from .65 to .8 depending on series resistance(.7V)
