How To Make Memory Card

Memory Card Circuit:

There are two memory card diagrams given separately in this circuit. These circuits work and generate different frequencies. To differentiate the frequency, a signal must be sent from Arduino to this circuit and the output will be a kind of frequency. The VR resistances are given separately to separate the two circuits. 10k is given in one and 1k in the other. And below is the diagram for the diagram of the Arduino circuit....
