You might consider using either the Motoron's current sense or an external current sensor to monitor your current draw

This configuration of the A-Star 32U4 Prime SV includes microSD support

and can be used with the PhidgetLED by simply soldering them to a connector-wire and inserting the wire into any PhidgetLED board output

26:1 Sub-Micro Plastic Planetary Gearmotor 6Dx16L mm Raspberry Pi You might consider using eitherThis tiny, cylindrical gearmotor consists of a coreless brushed DC motor and a 26: 1 plastic planetary gearbox. The entire assembly has a diameter of just 6 mm (0. 24) and an extremely light weight of 1. 2 g (0. 042 oz), making it a great actuator for miniature robots and very small mechanisms. Key specs at 6 V: 2500 RPM and 35 mA free run, 1. 5 oz in (0. 1 kg cm) and 400 mA stall. 26: 1 sub micro plastic planetary gearmotor next to a micro metal
