Setting digital pins as output / input

[RobynD]

Great program. Used it to make LCDs blink and change and respond to Scratch. I can see lots of uses for it.
I could not see how to turn a digital pin to input / output. I know for the Uno that is important because it turns on the pull up resistors. It's useful anyway.

Can you help?

Robyn,

 

Turining on the digital output is simple :

 

Select either Pin 10, 11 or 13 as follows :

 

 

Use the if loop to detect the digital input :

 

 

Hope that helps

 

Regards

Gary

Hi Robyn,

Did you mean how to set up a pin to input or output in S4A or turn it on? You can't do the first thing, because the pin mapping is set up both in the Arduino "firmware" as in the S4A sourcecode. You could change it in both but pitifully is not as simple.

You can find some help at this thread: https://groups.google.com/forum/#!topic/s4a-community/coS4WfG3vgU
