I am building a circuit consisting of seven LDR(sensors) namely using one of the vt900 series photoconducitve cell.Since I am going to control the LDR through the microprocessor , I am using either one or two pins from the microprocessor, meaning I also need to multiplex the connection to the sensors,. Plz I am very lost and have no idea how to build the circuit of this kind,
