Hi all,
I've got a question about the CHI030 project board (18m2) http://www.picaxestore.com/index.php/en_gb/picaxe/project-boards/chi030.html
I am using it with the 5v regulator and a 12v transformer but when I check the outputs with a multimeter I'm only getting 2.44v through the darlington driver buffered outputs.
The direct outputs are reading 12v. Photo below. Only one LED connected for demonstration purposes.
Is it not possible to get 12v through the darlington driver? I'm using it with a potentiometer for speed control of flashing LEDs - there will be 12 LEDs driven from the board so I'd prefer to go through the darlington driver rather than drive from the Picaxe chip directly.
Any info would be appreciated. The instructions seem to indicate you can use the darlington outputs unless I'm misunderstanding it.
Thanks,
Jennifer,
