Hi, I had everything working great yesterday. Ran all the module tests, performed the calibration and Nybble worked great using the IR remote and serial monitor commands. Suddenly today it made some erratic movement and all the servos pointed in wild directions. I tried to go through calibration again but now when I press 'c' for calibrate I only get a short beep then nothing happens and no commands work through the serial monitor. I reloaded the sketch but get the same behavior. It is not the batteries because I have been testing with a bench power supply.
Please help, thank you.
The cat refers to certain constants stored in the EEPROM when working. Some bit flipping may happen during voltage fluctuation.
