Step 1:

Teach mode: After a reset the robot arm follows the teach in arm while simple mapping the analog inputs every 25ms to the servo motors. Pressing the button stores each servo position in a array

Play mode: Double press the button switch to play mode. The sketch reads the array step by step and and moves the robot arm. For cool loocking movements i added a routine calculates different micro steps for each servo to have moving start and end sync on all axis. Also added a ramp for soft increase/decrease velocity. Shorter travel distances the robot does slow, longer distances with faster speed. Its all about timing so my thoughts in this moment
