Hello Experts. I need your help with the Automatic Hallway Light project I am ready to start building. At a first glance, (before I purchase parts) I would like to ask a few questions:
1. The way I understand the schematic, the X3-1, X3-2, X4-1, X4-2, X5-1, and X5-2 circles are points where I am supposed to be connecting the infrared devices? Please correct me if I am wrong.
2. If I build this circuit and place the receiver/transmitter in the hallway of width approximately 36”, my ceiling fixture lighting can be turned ON/OFF automatically. Please confirm.
3. IR_LED1 and IR_LED2 have ‘X’ as connection points. Why there is only one X4-1 red next to the IR_LED2 and one X4-2 black next to IR_LED1? Shouldn’t each ‘X’ point be marked?
4. How are we connecting the two unmarked ‘X’ points between IR_Q1 and IR_Q2?
Please see the attached pdf file of the Nuts and Volts magazine (December 2015) and the schematic of the subject circuit. Thank you all for your help.
