Stage of our geocache Qtouch
thingiverse
Input a sequence and let the microcontroller verify your answer, awarding you with a new code to progress to the next level for this clever geocache: GC50QG0.http://coord.info/GC50QG0 You will need to submit a sequence, after which the microcontroller will measure the capacitance of each button. Enter the correct sequence to unlock a fresh code for the next stage. The code was crafted in C, with custom electronics featuring an Atmega 328p chip. This self-contained unit is powered by three AA batteries, offering enough juice to last for one year. The system is activated when a magnet is inserted into the triangle - cleverly concealed inside a bug. https://www.youtube.com/watch?v=ycI_N5U1LJ8
