Weird Stackable Header behavior


#1

Hey all,
I’ve been having a really weird problem with my protoshield in terms of actuating the fans. I’ve been fiddling with the fans for a while now, and I can’t seem to get them to work. The fans are wired correctly in terms of polarity in the grove connector. The Relay board is working fine, and the Arduino is outputting the correct voltages from the correct pins (14 and 15, since hookup wire directly into the grove connector from the arduino turns on the relay and therefore the fans as expected). However something may be wrong with my protoshield. I have tested sending signals through the pin and out a grove wire attached to the connector with success, but for whatever reason when I plug the protoshield into the arduino and try to actuate the pins, the signal never gets to the grove socket! I’m incredibly confused, as when I supply voltage to the bottom of the pin (in the female header on the arduino) and try to test hookup wire attached to the top (on the side with the grove sockets), I can’t even locate the signal.

Is it possible that my headers are ‘defective’ or that I have somehow accidentally created a cold solder joint? Please let me know if you’ve experienced the same

@JamesO: can you send detailed pictures of your soldering work and the proto shield ?

You can purchase the helper from plantcubed.com that replaces the proto shield, base shield and the DC relay. It’s simplifies the wiring process.

Thanks for all the help, as it turns out some extra solder creeped up the pin and simply prevented it from making a consistent contact. Cleaning the pin and adding a bit of extra installation force seemed to solve the issue.

Wow. the first Food Computer centric on-line store.

Exciting times…

@treb0r Thanks for the support!

@Rckco is that your store?

Will you be shipping to Europe?

Someone should open something like that over this side of the pond!


#8

Well of course. For some reason most of my sales are to the EU.


#9

Unfortunately it seems that we won’t be in the EU for much longer :rolling_eyes:

As soon as the V2 is out I will come and buy lots of stuff.

Still waiting to hear about version 2.0.

Are you planning to supply parts once it is live?


#11

I could, but Im working on my own design. Should be ready soon. I do have a better ph/EC probe thats available.
