Project 2: Controlling 8 LED's question

Post by Ezra » Sun Dec 28, 2014 10:20 am

I am very new to the Freetronics eleven. Manged with the first project in the project book and now tinkering with project number 2. I have compiled the programme and run the Eleven. Only 7 LED's light. If I add outputs then the first LED won't light nor will the 8th LED. If I subtract outputs then there is always one less LED lighting than the number selected. e.g. If I select 4 LED's to light, only 3 light up.

I don't know what I have done wrong. Can't see a mistake in the programme.

You might have an older version of the printed guide, please try with the latest version from:

Thanks for your reply. I have had no luck.

I may move on to the next project and try my luck and maybe come back to this one.

I've had a similar issue... but with the 2nd part where you create a longer array and remove the 2nd for loop in the void loop() {} and I simply increased the var ledCount to 15 and it works.

Ezra if you come back to read this it might be worth showing us your code :)
