// Code Example - Arduino Nano Wiring // SDA → A4 SCL → A5 // VCC → 5V GND → GND // This toggles the DAC output between 0V and ~2.5V every second. The value 2048 is half // of the 12-bit max (4095), giving half the supply voltage. #include #include Adafruit_MCP4725 dac; void setup() { dac.begin(0x62); } void loop() { dac.setVoltage(2048, false); delay(1000); dac.setVoltage(0, false); delay(1000); }
