wiring a: DFR0151 - DFRobot Forum

2011-12-01 19:59:52 The RTC module is not modular, it does not insert. You need to make the wiring. The LCD uses Digital pins 4,5,6,7,8,9. You can use all the other pins, you might need to use different kinds of wire or solder some wire to the LCD shield to achieve the proper connection.

Just create the same wiring as the wiring diagram, but instead of directly on the Arduino, do it on the LCD Shield.

2011-11-30 22:59:54 ok, still have a problem. If I stack my dfr2009 lcd shield on my dfr0001 dfrduino duemilanove there is no spot to attach my dfr0151 clock to it. The diagram shows using wires but I thought it was modular and would fit together. I don't have the clock hooked up yet, and my display reads

12:00:00 am
blue:0 white:0

At least I have a display, even though nothing changes.
Here's a copy of the sketch I will be using

2011-11-30 09:35:59 Ok, I got the picture open and see how to wire it. Thanks for your help. I'am sure more questions ahead. rjhudak1

2011-11-30 04:48:26 Thanks for the reply Hector. Part of the problem is I can't open the doc. up. I have a program that opens par files but it will not open. The other problem is that there is no where to plug this in. rjhudak1

2011-11-30 00:33:54 Hi,

Have you looked at the connection diagram included with the documentation?

[url=https://www.dfrobot.com/index.php?route=product/product&filter_name=dfr0151&product_id=511]https://www.dfrobot.com/index.php?route=product/product&filter_name=dfr0151&product_id=511[/url]

Since the LCD is a shield you should be able to just plugin to the same pins on the LCD as the connection diagram shows for the Arduino Hector
