Hello everyone, I'm a beginner when it comes to Arduino, and I'm seeking some guidance regarding power supply requirements for my Arduino project using an Arduino UNO R3 (ATMEGA328P-PU) board. I've done some research, but I still am confused on what to do. I would greatly appreciate advice from experienced individuals.
Here are the components I will use with my Arduino UNO R3:
- Breadboard
- MG996R Servo Motor
- MG946 Servo Motor
- Inductive Proximity Sensor (LJ12A3-4-Z/BY)
- Capacitive Proximity Sensor (LJC18A3-H-Z/BY)
- LCD Panel Screen (2004 Green I2C)
- LCD1692 I2C Interface Adapter
- Humidity Sensor (DHT11 Module)
- Temperature Waterproof One Wire Sensor (Ds18b20)
- OV7670 Camera
- Ultrasonic Sensor (HYSRF05) x 6
Considering the components involved, I'm unsure about what appropriate power supply or battery configuration to use. I know that each component may require different operating voltages and currents (3.3V, 5V, 6V, etc.). Additionally, I'm wondering if a step-down buck converter would be necessary if the power supply voltage is high. Would I need to use two separate supplies where one is powering the Arduino board and the other is powering the entirety of the components mentioned above.
Could someone provide guidance on how to properly power each component with their respective voltages and currents? Any suggestions, advice, or recommendations would be really helpful to the success of my project.
Thank you in advance .
