By using this electronic circuit you can control 64 LEDs using 64 switches but the link between them is only 5 wires !
It could be an educational project to illustrate how the shift registers works.
You can even use LDR instead of switches !

Transmitter Circuit:
You can use LDR instead of switches.
You have to preset the potentiometer.
In case of using LDR instead of switches the potentiometer adjust the light sensitivity.
The diode 1N4007 close to the battery used for reverse polarity protection.
You can only use Mosfet not BJT (because BJT disturb the current sensing resistor due to the current flow from base to emitter).
Input voltage range is 7V to 30V for both circuits.
