Consider the circuit, HC908QY4 is the heart of all. It uses a pin PTB0, PTB1 and PTB2 to control and display the text on the LCD. This leads to (shift regiter – serial to parallel converter) CD4094 that we will provide the data bus to LCD display.
In the CD4094 data are synchronized on the rising edge and the LCD display will take on the falling edge shows us that this signal can be shared.
If you want a wireless audio system there are several ways to do it. The simplest is to use infrared light that is modulated audio signal to be issued. In the circuit that receives light, it will demodulates, amplifies it and deliver it to the loudspeakers.
The magnetic induction or magnetic flux density, symbol B is the magnetic flux per unit area in a section normal to the direction of flow, and in some modern texts called magnetic field strength, since it is the actual field.
