The Hoz writes to inform us of another Arduino related iPhone app known as OTOduino. This free app allows you to interact with an Arduino and monitor/control analog and digital IO ports in real-time via a simple audio jack interface. It’s currently available from the iPhone app store.
Check out the OTOduino project support page for full details and to download the necessary supporting Arduino library.
Thanks Hoz! Via the contact form.
