Turn an RFduino into an iDAQ-BT
This sketch, combined with the iDAQ-BT iPad app will let you turn your RFduino and iPad into a chart recorder that can monitor any analog input and plot the results in real time on your iPad.
For detailed instructions on setting up your development environement, and programming an RFduino, visit the RFduino github page: github.com/rfduino/rfduino
To use this sketch: You must first purcahse an RFduino device from rfduino.com. Remember to get an appropriate power source with your order. The RFduinoruns well from a pair of AA batteries using their battery shield, or it can be powered by a 5V USB supply combined with the USB shield. You will also need a USB shield to program your device. Once your computer is setup to work with the RFduino, upload this sketch to your device. It will immediately begin transmitting analog data to your iPad! Use the BT-iDAQ App from Tactition Programming to monitor this data and see your signal in real time.
