INA 219
- arduino INA219 library - read voltage and current File:INA219 library.zip
- Simple testing, test a LED:
| Arduino UNO | Target - LED | INA219 |
|---|---|---|
| 5V | x | VCC |
| GND | x | GND |
| GND | LED - | x |
| 3.3V | x | VIN+ |
| x | LED+ | VIN- |
Test result is:
Bus Voltage: 1.81 V Shunt Voltage: 0.19 mV Load Voltage: 1.81 V Current: 1.90 mA
