I am in need of a motion sensor for something, and I have this HamShield that I got from KickStarter recently.<\/p>\n
<\/p>\n
heres some code I have mashed together that *MIGHT* make the radio send an SSTV image when motion is triggered..<\/p>\n
<\/p>\n
I have to rest it and refine it first! its just mashed code from examples!<\/p>\n
