Low Voltage AC Source (Part 4)
Today, we are going to look at a third method for generating a sine wave with an Arduino: using the Arduino's PWM output as DAC.
Low Voltage AC Source (Part 2)
Let's move on and generate a sine wave signal for our AC source. Our first approach: using a DAC.
MCP4725 DAC Module (Part 2)
DACs are often used together with analog circuits. As an example for this we will use the MCP4725 to build a programmable current source.
MCP4725 DAC Module (Part 1)
One of the limits of the Arduino Uno is that it doesn't have a DAC. The external MCP4725 module is thus an interesting extension.
