Among dozens of embedded systems available worldwide, the RFduino remain a powerful and flexible platform for prototyping things. There are literally several additional accessories, kits, tutorials and related articles describing how this little microcontroller board could be used to achieve the best performances.
Like any other microcontroller used in robotics, the RFduino has limitations. But in this case, these limitations hold hidden benefits. Not only stability or a low power consumption, there are other essential features with interesting things for prototyping.
Based on the Arduino microcontroller, this little device will let you hacking almost anything and can communicate with an iPhone or Android smartphone via Bluetooth LTE communication.
If you already are familiar with Arduino IDE, this is good because the RFduino share with Arduino the same IDE.
Compatible with Arduino shields, the 32-bit ARM Cortex-M0 can control a series of sensors, motors, or shields through 7 GPIO pins.
Because you may not have any idea how RFduino can be used, in this post I give you 9 opportunities to discover some of the most powerful features of this little device designed to work for prototyping things.
Rfduino – read analogue sensor
This guide shows you how to read data from an analog sensor and display the values on an iPhone. The communication between the smartphone and RFduino is via Bluetooth. The circuit is simple, only one sensor has to be connected to the GPIO pins, while the circuit is powered by 5V power supply.
