Hi, I'm trying to determine what is required to build a hall effects limit switch that matches the one found at the link below. Michael Omiccioli - Google+ I have the hall effect switch, I have the proto board, the resistors and LEDs. I am not sure about the two taller components on either side of the LEDs but they could be PNP Transistors (2N3906). I'm a newbie at electronics so any help would be appreciated. I'm really trying to learn this stuff as much as possible. Any help identifying the parts and suggestions on schematic would be appreciated. My goal: Created sensors that have two LEDs. One green (normal on) and one red that comes on when switch is triggered. The two LEDs alternate between on and off depending on the switch state. Green is good, Red is bad! Thank You
