For example, if you write analogWrite(3, 255/2), the result is a square wave on pin 3 whose width was divided by 2. The full width will produce 5 volts, so this wave will produce 2.5 volts. Take note: ...

Arduino has taken the product “maker” world by storm and one of the more popular Arduino modules is the Analog Devices AD9851 DDS waveform generator. An Internet Web search for “Arduino DDS” showed ...

1. This very-low-frequency sine- and square-wave generator requires few components, but provides low-distortion outputs (derived from LTspice simulator).
