These boards simply provide 8 LEDs connected to 8 pins (a flying lead provides ground).
Circuits dont get a great deal simpler than this!
Each pin controls a single LED. When the pin is set to output a 'high', the LED will light.
The on-board current-limiting-resistors are suitable for 5v supplies, but all except the white model will work at reduced-brightness on 3v (The white LEDs need more than 3v to light sensibly).
Sample code that demonstrates all 8 LEDs is available from the link below or on the downloads page.
These were previously available with an option of 'right-angled pins' pins. The vast majority of people
just want the plain 'straight pins' option, so we've dropped that option.
If you really, really want right-angled pins (or even no pins at all), just order the normal 'straight pins' version and drop us an email at the same time - we'll sort it out for you.
The following versions are available;
|Red||5v/3v||slightly dimmer at 3v|
|Yellow||5v/3v||slightly dimmer at 3v|
|Green||5v/3v||slightly dimmer at 3v|
|White||5v||will be very dim at 3v|
