Re: Multiple RFID Shields on Etherten

Welcome to the world of Arduino! There are no stupid questions. :) The current design of the RFID shield does not allow for multiple RFID readers or multiple relays for doors. The shield uses specific pins for talking to the RFID reader and to control the door relay, that cannot be changed on the sh...

Re: CNC SHIELD

Sorry for the late reply. The original board (which was developed as part of the HackCNC project for the LCA mini-conf) has 2 stepper drivers on board, and output ready for connecting a third stepper driver, such as a Pololu A4988 or Pololu DRV8825. Therefore the board will control 3 stepper motors,...

Re: DHT11 and 16X2 Lcd display

Hi Sencorp.

Any chance you could link to/post the code your got running? I'm sure that others who come across the same sort of issue would find it invaluable.

Re: NDRIVE - Nichrome payload cutdown advice

Welcome. I'd have a crack at using the NDRIVE in the way you tried, to see what the issue is, but I don't have one to hand. Will see if I can arrange to try it myself and get back to you. FWIW: If you have problems with the relay at low temp, I would suggest trying using a FET directly (eg: somethin...

Re: Reclaiming D4

FWIW: This is also true of D11 (used for DI on the uSD), and D13 (used as SCK on the uSD).

I'll pass along the suggestion to Jon & Marc and see what they say.

Re: How To Upload A Sketch To Your Arduino Via A Network

I believe that this part of the process must be done with an ISP, in the same way you uploaded the bootloader. Note: Once you connect the ISP and want to upload the sketch, select the correct ISP using the options under "Tools -> Programmer", then select "File -> Upload Using Programmer". This will ...

Re: NDRIVE - Nichrome payload cutdown advice

Edited. Original post quoted below: Sounds like you're getting voltage leakthrough from the Drain (D) to the Gate (G), causing the FET to stay switched on. Put a resistor between the Gate (G) and the Source (S), probably about 100k, and see if that helps. Note: It's also advisable to put a 10 ohm re...

Re: Ethermega fried the 5v regulator

Hi Mike, From what I believe this is not a common problem, but I may not be across everything, so hopefully Jon will reply to that question. If anyone gets this issue and wants to confirm if the regulator is working, you can put a multimeter between the DC IN pin (on the jumper header that selects b...

Re: Keyboard and Mouse HID

To stop spammers we've had to limit file uploads/attachments so that you have to post a certain number of posts before you can access those features. Hopefully if efry or mbresciani see this, perhaps they can repost the updates files as attachments? Both of them have posted enough posts and should h...

Re: Sketch uploads but does'nt run

One difference between the Mega and the Leostick is that the bootloader is (at least partly) uploaded each time you upload a program to it. This is due to the fact that the 32u4 chip on the board doesn't just run your program, but also talks to the USB. This is what allows you to reprogram it to do ...
