Tutorial: How to Use AMS1117-3.3V (Voltage Regulator)
The AMS1117-3.3V voltage regulator is ideal for powering low-voltage circuits. Suitable for beginners.
What you need
- Arduino Uno
- variable resistor pack
- connection wires
Steps
- Connect the regulator input to the power source
- Connect the ground to the GND pin of the regulator
- Power the circuit with a value above 3.4V (check the datasheet)
- Verify that the output voltage is stable at 3.3V
- Connect the output to the device to be powered
