// welcome with Rainbow and fast blink push n times
// 1 push  several move on-off and back to menu
// 2 pushes  same with pfm speed changes
// 3 control  with most TV IR 1pulse stop, 2,3,4,5 move
// 4 demonstrate log dim
// 5 count in binary
// 6 test accelerometer Gy521 value in terminal 4 orientations on leds
