Amplitude control is achieved (pin 5) through the multiplier function, as i Y. The (pin 6) output is a bipolar current that is integrated by IC2. The first-generation scheme is illustrated in detail ...

The complete circuit diagram for the AD9833 and Arduino Based Function Generator is shown below. We are going to use the AD9833 with Arduino to generate our desired frequency. And in this section, we ...

Fig. 1: Author’s prototype for Arduino based frequency generator. Circuit diagram of the sine, square and ramp Arduino-based frequency generator is shown in Fig. 2. It is built around an Ardunio Uno ...

The actual circuit of the generator is built with three LM386 ICs. It produces two frequencies, selectable via double-pole double-throw (DPDT) switch S1 ( Fig. 2 ) . When the switch is in position ...
