QUESTION - interrupteur arduino

-

bonjour je suis tous nouveau dans le bidouillage avec une arduino , et donc j'ai encore beaucoup de question,

en voila une ^^ pour un projet j'ai besoin de pouvoir via une application contrôler mon arduino pour qu'elle face office d'interrupteur , je m'explique :

j'aimerai supposons qu'une lampe relier au secteur , s'allume ou s'éteigne mon bon vouloir, comment donc réaliser ce montage sur mon arduino ? sans tout casser en sachant que je serais brancher sur secteur avec cette fameuse lampe.

merci de vos réponse
cordialement.

bonjour,
jouer avec le 220 peut être dangeureux ;)
regardes du coté des relais 5-220v
