You're dead right, it's good to get as much information on the forum as possible and there's always more than one way to skin a cat

Thanks,
at the moment I only need one digit to have a decimal point and therefore I just AND the required digit with 0x7f and that switches on the DP for just that digit position whatever the number is.

:D :D :D Who writes this stuff .... :o come on guys/girls please! Check that you have the shield firmly inserted into your Arduino board and that part of the shield is touching the Arduino's USB connector casing. That's exactly what you shouldn't do !!!!!! either push the shield in only so far so th...

Hi, I've found out what the problem is, I don't know why I didn't spot it before :oops: one of the pins on the display is contacting the USB housing on the UNO therefore grounding the segment and keeping it illuminated. I do think this will happen to most people who purchase the module. I've also fe...

Im not too bothered by the led, I can always remove the led from the uno.

My big issue is with the segment stuck on the display, I am going to try the code again from the forum and if it stil does it I'll feedback via ebay case.

Thanks for your help.

Thanks for the quick feedback. Based on information found here http://startingelectronics.com/articles/arduino/uno-r3-r2-differences/ showing the differences between the original UNO, R2 and R3 it looks like both the UNO and the R2 versions had the same LED circuit (this will be a lot of boards) the...

I think I've spotted the issue with LED D1 being permanently on. The existing LED on the UNO uses a 5V output to switch it on whereas your LED relies on a GND to switch on the LED this means that there is current flow between 5V and Gnd through both LEDs. https://dl.dropboxusercontent.com/u/2253850/...

Here's an example of the problem with the original buzzer code void setup() { /* Set the buzzer pin to an output and turn the buzzer off */ pinMode(POT_DIO, OUTPUT); digitalWrite(POT_DIO, OFF); } The pinMode and digitalwrite should be to "buzzer_IO, OFF" not POT_DIO. This also occurs elsewhere in th...

LED Code is wrong, correct code for LED sketch below.
Also because of the 'L' led (i think) LED D1 is always illuminated

Also the bleep code is wrong you don't use the buzzer output variable the pot in is used in error. This is the corrected code not the original /* FILE: ARD_Multifunction_Shield_Buzzer_Example DATE: 28/05/14 VERSION: 0.1 REVISIONS: 28/05/14 Created version 0.1 This is an example of how to use the buz...
