Good practice shield

I like this relay shield for the following reasons: - Opto-coupler on relays for better insulation - Indicator lights, and manual buttons for relays, convenient for testing. - Integrated design well done - Simplicity of implementation The negative points are: - Pine used unmodifiable (pine 2,7,8,10) - Need an external power supply to operate the relays. It's a shame to use pin 2 for output while this pin can be used with interrupts. Without adding a library, pines with interruptions are rather rare on an arduino.

Bon shield pratique

J'aime bien ce shield de relais pour les raisons suivantes: - Opto-coupleur sur les relais pour une meilleure isolation - Témoins lumineux, et boutons manuel pour les relais, pratique pour les tests. - Design intégré bien fait - Simplicité de mise en oeuvre Les points négatifs sont: - Pin utilisées non modifiable (pin 2,7,8,10) - Besoin d'une alimentation externe pour actionner les relais. C'est dommage d'utiliser la pin 2 pour une sortie alors que cette pin peux être utilisée avec des interruptions. Sans ajout de librairie, les pins avec interruptions sont plutôt rare sur un arduino.

Pas mal

Je l'ai utilisé sur un méga avec le conseil d'administration méga. Ma plainte est que je souhaite qu'il soit monté à 180 degrés de sorte que la fin du conseil pèse sur une autre section du panneau de discussion. Sinon, le bouclier lui-même fonctionne bien et offre une flexibilité.

Not bad

I used this on a mega with the mega breakout board. My complaint is that I wish it was mounted 180 degrees so the end of the board hung over another section of the breakout board. Otherwise the shield itself works nicely and offers flexibility.
