(not urgent things, but somethings we want to implement at some points)

To obtain a voltage signal, a pull-up resister and a DC voltage are needed at the receiver stage because the signal is generated with a transistor.
An easy way to check this BO system is putting an LED on the receiver stage as described in the figure below. In this case if the signal is ON the LED lights up and vice versa.
