Re: 4 Channel Relay Module

Hi Andrew, I've been running a test of a RELAY4 here today to try and duplicate this, and no trouble yet at least. I'm driving 12V coil relays, have a 12VDC supply into the RELAY4 and EtherMega running the test, and using digital output pins to control the RELAY4 input lines. Would you be able to se...

How to unlock a LeoStick with a hung sketch (and why)

If you have an older V1.0 LeoStick then it is possible to update to V2.0 . Scroll straight t...

There are a few things to look at in the setup: The example I have run is from the 1.0 IDE and is File>Examples>SD>listfiles - In setup() the SPI CS output pin needs to be 53 (10 on most boards, 53 on all Mega type boards) so line 32 become...

Re: Issue with SD card and the IDE library.

Hi Steven, What kind of errors with the SD card do you get on the Mega? Looking at the schematic of the EtherTen and EtherMega, at first look the functionality from the library point of view should be just the same.
