RGB LED Shield diagrams for documentation purposes

I'm back! I am still having trouble, I am waiting on a 300mA rated bulb to come, but I am using resistors in order to get the current down to 20mA in order to allow me to use a regular 5mm Red LED. I am using a 9V battery to power my board. I know it is rated for 12V-48V so I do not know if the 9V is just not enough to power the driver, or what? I have voltage across the light, and it will light up, only when i am trying to measure the resistance and the multimeter's leads touch it, but the light never turns off, or dims.

I do not beleive there is a minimum current limit for the Infineon board, it is simply the set constant current in the demo sketch, the board is actually programable for almost any current up to the MAX of about 700mA per channel I beleive and up to 40V ish supply, th eboard is degined to drive the LEDs directly with NO seriese resistors, you can get it to work with LED strips or other LEDs with series resistors but the results are not ideal, just functional

so using the default sketch and a little iddy biddy LED, you will have a high probability of frying it instantly (20mA vs 300mA), you will need to adjust the configured settings at the beginning of the sketch

I believe I covered this topic off when doing the IOT of holiday lights challange, see here http://www.element14.com/community/groups/arduino/blog/2014/12/15/byob-party-re-configuring-the-infineon-for-regular-12v-led-strips

Hope this helps

Hello,

So I am currently working with the shield, but have run into some trouble. I am trying to power a single red LED using the red LED channel from the board. I am using a 9 volt battery as the power source for the shield. I have tried running the example codes provided by infineon. However, those are not working to power the LED, neither will my manipulated code that is only supposed to drive only the red LED channel. You can find the manipulated code here. I am not sure what is wrong, almost positive it is a case of user error, but any guidance would be helpful!

Thank You!

Hi [mention:b0bc65b9ecdc4307bd967592f00e340a:e9ed411860ed4f2ba0265705b8793d05] do you have the Infinion RGB shield in a vector format? I'm trying to get it into Fritzing and Fritzing is not playing nicely with bitmaps and wants a SVG.
