Arduino digital to analog converter. GY4725 MCP4725 Tutorial. With Datasheet.

Arduino has ADC ( Analog digital converter) and PWM (Pulse with modulation) but if you need true Analog out, you are out of luck. But all is not lost. We can add the analog capability to Arduino with MCP4725 12-Bit Digital to Analog converter. This nifty chip has also on board EEPROM so you can save your last value in case of power failure.  This chip has also 3.4Mbps Fast Mode I2C (Unfortunately Arduino does not support that speed), with Arduino you can update the output at around 200KHz. So lets jump in…
