 +  * [[http://​www.youtube.com/​watch?​v=s6bs1rrOwxo|Shimi robot]]
 +  * intro to actuation and motor control, open-loop vs closed-loop systems
 +  * building of the slider kit in team: putting together the shield and all the pieces ​
 +  * basic motor movement
 +  * {{:​courses:​motorslider_01.zip|motorSlider}} Arduino sketch to run slider commands from serial
 +

 +
 +====FRIDAY====
 +  * master-slave setup (one slider with a encoder as input, other slider follows)
 +  * event based behaviours
 +  * putting it all together, refining sequence, context and use-quality. ​
 +  * control multiples sliders from one computer/​device
 +
 +==== Parts drawings ====
