dealing DC motor noise

To come back on my previous post.  So putting a ceramic 100nF capacitor on the DC motor solved the interference (noise) issues.  I did a lot of reading on the internet.  Google was indeed my friend.  I had no clue what size of capacitor to use but I ready few articles where 100nF was proposed […]

Breakthrough ??

After trying a lot of things to solve the noise issue from the DC motor, I finally decided being without ideas to replace the DC motor. And guess what. Now the infrared reader keeps receiving correct values. The big question is now of course what is the difference between those 2 DC motors. Maybe too […]


I have been done a lot of research and reading the last few days to figure out how I can solve my problem.  Finally I ended up at the following page about DC Motors.  See DC-Motors. There is a part about noise caused by the DC motors.  To isolate both circuits (Raspberry Pi linked/Battery holder […]
