<< Summary

Use the Adafruit MCP4725 with a Raspberry PI, in Java Raspberry PI
Send an analog signal

The board we are talking about here is this one.

We assume you've enabled I2C on the Raspberry PI.

What this demo does

The Raspberry PI is sending a sinusoid signal to the led, and as a result, the led is glowing up and down, and not just blinking on and off.
