Here’s some video from Gert on the new revision of Gertboard, an expansion board for the Raspberry Pi which brings out the GPIO. There are some lovely demos of Gertboard enabling the Raspberry Pi to work with an analog slider controller and a motor here.
Apologies to Gert, who sent me this last week while I was offline; I only saw it today. The “next week” he mentions is, in fact, this week – hooray! A general rule for everyone: if you want to get in touch with me and it’s important, please email rather than PM me. (Famous last words before being buried in a ton of mail.)
Gert should be able to answer your questions below.
