I am working on a project with Arduino, 2x servos - FS5106R and SM-S2309S and 1x nRF24L01 Transceiver. Apart from doing the projects coming with the Arduino starter kit I don’t have much experience, so consider me as a beginner.
More information on the project: Essentially I am designing a sort of harmonograph, which needs to run on a battery for max 2 hours. I am using a nRF24L01 Transceiver to receive data from a gyroscope and control SM-S2309S servo, while other FS5106R will be running continuously at the same time at very slow speed (controlled by potentiometer) and nothing heavy would be attached to it. After reading various posts I understand I shouldn’t run the servos from the arduino, but external power supply and this is where my trouble comes.
I would appreciate if anyone can advise me on what battery power supply to use. A schematic diagram is attached to show the system.
The requirements are:
- be able to power the system (both arduino,transceiver and servos) for at least for 1 hour.
- be able to deliver power in case SM-S2309S is later replaced by FS5106B servo. Therefore having 1x FS5106B and 1x FS5106R.
- Smallest size is preferable.
I am happy to provide extra information if needed. Thanks in advance.
