I have a pulse transformer with a ratio of 1:40. I have a 1000V pulse going in so thats about 40,000V coming out. It creates a spark gap. It works fine.
When I bring my Arduino relatively close to the transformer I get interference. For example I have my Arduino outputting an AnalogRead value from A0 to the serial monitor randomly. Its consistently about 300 or whatever. As soon as my transformer does a pulse the 300 jumps to 500 and settles back down to 300 shortly after within half a second. The Arduino is not hooked up, it's purely EMI through the air from the pulse transformer that is effecting it; and my scope leads too. I can even see the EMI on my scope if I bring the leads closer to the pulse transformer during a pulse. How do I stop this?
Can I put my Arduino in a tin can or something? Can I wrap the transformer in tin/aluminum foil?
