I built my first Otto DIY Robot this year !
Asked a question 2 years ago

I can use some help with Arduino Pin Change Interrupt programming with the Ultrasonic Sensor (SH). Connected to pin 8 (trigger) and 9 (echo) according to Otto DIY defaults. I do not want to change the default Ottodiy pin numbers of Servos and other I / O because I always want to be hardware moderately compatible with other people. My intention is to start or stop the Robot with a simple hand movement. At the moment I am using Otto_allmoves.ino. Starting the Robot was not that difficult to build in. But how do I stop the Robot in the same way.
