Question about Uniden Hand Held Scanner - BC-246T 2-Way Radio
I want make a display to demonstrate how a hand held barcode scanners can be used to open a spring loaded door. Can this be done inexpensively for a class display?
If you were to have it open using any barcode, you could build a circuit that uses the beep of the scanner when it reads a barcode.
If you wanted it to only work with specific barcodes it would get far more complicated, you could right a program that displays a white or black box in a corner of your computer screen and just build a simple light detection circuit and tape the CDS Cell of the circuit on your screen where that box gets displayed.
