Hi!
I want to make a small LED monitor for my motorcycle, so I can read the engine's temp, oil temp etc... from there.
I am using Arduino Nano for this project and the power supply will be come from the motorcycle's battery.
When the engine is running, I guess the voltage from battery "is not" a pure DC voltage? Also, the power supply from the motorcycle is "dirty" & lot of "noise" and sometime will have voltage spikes? So the first step I think is to have a clean power supply.
Below is my schematic, and I would like to seek your advice, should I put some capacitors to the INPUT & OUTPUT side? to absorb the voltage spikes, clean the noise and protect my dc-dc buck converter? If yes, is C2, 10uF enough to absorb the voltage spikes? I assume C1, C3, 0.1uF can provide a smooth Vin, right?
My Mini DC-DC buck converter. It already have two ceramic capacitor on it.
Many thanks
