problem atmega 328 with EMI RADIATED.

The micro atmega 328 restarts near it to a high voltage cable. In this case of automobile spark plugs cable. i need Develop a robust design for electromagnetic compatibility for not restarted atmega.
Im from argentina. My inglish is bad jaja

Make sure your spark plugs are the resistor type. Plugs with an internal resistor create less EMI.

Hi friend!!! thanks for your answer!!
But I can not change the ignition. It is better if i work in my circuit.
some inductor could help?

You need to either keep the circuit well away from the cable, or else completely shield it in a metal
box with shielded cables. Car ignition cables are unshielded and thus a nightmare for interference.

[ Perhaps modern vehicles do have shielded cables these days, it would make a lot of sense ]
