The goal of this project was to create a system which exploits some of the design flaws in the iClicker classroom polling system such as flooding the base station with bogus answers and changing other student's submissions. The software utilizes a 900 MHz packet radio capable microprocessor and is built on top of the work done by @wizard97, @orangeturtle739, and others to reverse engineer the iClicker protocol.
The code is written such that the microprocessor does all the work and commands are issued to the
board via Serial. Commands should end in a \n (which is default in the Arduino IDE).
The code attempts to keep track of every answer that is submitted to the base station. The system is likely to miss a number of packets as it can't receive and transmit at the same time. A more optimal solution would be to use 2 feathers: one for intercepting and one for transmitting.
I am using the Adafruit Feather M0 RFM69HCW. To setup Arduino to work with the M0 you will need to:
- Go to File > Preferences and add
https://adafruit.github.io/arduino-board-index/package_adafruit_index.jsonto the Additional Boards Manager URLs - Go to Tools > Boards Manager then install
Arduino SAMD BoardsandAdafruit SAMD Boards - Install the iSkipper and RingbuffCPP libraries to your arduino library folder.
You'll also want to solder an antenna to the board.
The use of this device and software may be frowned upon. Depending on how you use this device, it may be considered academically dishonest or harmful to the other students in your class/lecture. I am not liable for anything you do using this device or software.
Also: I made this because I could and thought it would be interesting. Not because I intend to make extensive use of it myself it myself.
I have three personal rules for using this: 1) I don't spoof attendance, 2) I don't use it to cheat by looking at how other people are voting, and 3) I don't mess with other peoples' answers on polls which will count for a grade.
