Voltage and Current Load Check

Projects General Guidance
1

hello all,
I've got a pretty cool project in the works, and I just want to make sure that this will all work.
I would like to power the following devices from the 5V pin of the arduino, which will be connected to a 4AA battery pack:
2 Parallax continuous rotation servos
1 micro servo
3 photo resistors + 3 10k resistors
2 LEDs + 2 10k resistors
1 piezo buzzer
1 BT11 Serial Bluetooth module
1 HC-SR04 Distance Module

Thanks in advance

Please post links to the datasheets for each of the items you will be using, which include the current requirements for each device

(otherwise we'll all be guessing exactly what devices you are using, and would need to spend a lot of time finding the relevant source information)

First thing, rethink the 4 AA battery pack. That is 6 volts which is too low for the Vin and too high to connect to 5V. Better a 9V pack and connect to Vin via the power jack.

If you're RC Qualified you can use a Lipo. If not, then don't.
