Osez la technologie… J’ai essayé d’être le plus complet possible

L’électronique et la programmation Pagode en papier carton; Les plus belles maquettes en papier; pagode Japonaise; japanese Pagoda; tie fighter, electronics led,command led; pic

 

L’éclairage de la Pagode est assuré par un microcontrôleur du type PIC 12F1822(40).

Deux led’s placée dans les alcôves illuminent les Buddah, leur intensité peut être réglée à l’aide d’un petit potentiomètre.

Le microcontrôleur gère également l’effet  »feu » au moyen de trois led’s, deux jaunes et un rouge.

L’effet est obtenu par un algorithme qui produit des différences d’intensités (par PWM).

Vous trouverez le programme C ici.

Le contrôle pourrait être fait à partir de n’importe quel µP, tel que l’Arduino, mais le choix a été fait en fonction de la place, en effet toute l’électronique tient sur une plaque à peine plus grande qu’un Arduino Nano.

Un exemple de carte « breadboard » est joint à la documentation.

Une simple alim 5V, du style chargeur USB, suffit à alimenter le tout.Les plus belles maquettes en papier; pagode Japonaise; japanese Pagoda; tie fighter, electronics led,command led; pic
