Abstract
Data is generated by writing or drawing on a sheet of paper placed on a specially made electronic writing board having matrixed conductor elements that are connected to the bases of transistors which get triggered and generate data when activated by the lead of a power pencil connected to the positive supply. The data is processed and transmitted. The reading board circuitry receives the signal and after processing it is displayed on the reading board. The system has all the electronic circuitry and memories necessary for its desired satisfactory functioning. Each unit of the system is made up of a writing board and a reading board for real time interactive communication.
In programmable lighting advertisements the data is displayed on a hoarding or any suitable area and a different addressing system is used.
