    Code for driving Galvos with Arduino Uno R3

    Together with this code I used Delta Flo’s library for the MCP4822 (link). The gotorate(x, y, r) function calculates the linear distance between the current and desired positions and interpolates the values based of the rate variable. This way it keeps the galvos at a constant rate and eliminates the some of the brighter dots […]

    My plan is to take an Arduino r3, a bog standard Chinese 20K Galvo set(link), and create a 32 band Audio Spectrum Visualizer. I forgot to get the option that comes with the split power supply so I ordered a +-15V power supply off amazon. Following the instructables by delta flo (link) I ordered an […]
