Issue With Voltage

Using Arduino General Electronics

Hi all,

when i start my "case story… :slight_smile: " when I load an relay to ignite an spark with some kind of http://bostonheatingsupply.com/images/products/detail/Laars_R2069300_NTHNTVignitorw.gasket285600btufront_53002.jpg to this kind of equipment http://img.ehowcdn.com/article-new/ds-photo/getty/article/151/130/86506894_XS.jpg, if the spark toch outside the desired steel, it restart,

is there a way to protect from restart arduino ???

A bit of a cryptic question there.

is there a way to protect from restart arduino

Yes but it is difficult and will need some working out as there is no one magic answer.

  1. Keep all wiring as short as possible and keep it away from the high tension.
  2. Apply transient suppression to all input / output lines you use.

  3. Apply lots of decoupling to the power supply.
    De-coupling
  4. Have a series resistor in line with the spark circuit of about 1M

Thanks Grumpy_Mike

really ;) will read caurfully

Where is the Arduino located here? Under the grill? In the house?

Hi oric_dan

oric_dan: Where is the Arduino located here? Under the grill? In the house?

Arduino is on grill :) (not on top)

I got an arduino connected to this http://store.arduino.cc/eu/index.php?main_page=product_info&cPath=16&products_id=113, that will star http://www.grill-repair.com/images/parts/dcs212333.jpg and spark from 220V.. (arduino is on 12v)

So i think, shouldn´t that grill-part, have all anti static capabilities?

Many tks kr

p.s. when i have arduino connected to laptop, always work...
