====== Lego SPIKE programming ======

  * Lego spike is newest lego programming kit, replacing mindstorm,
  * Lego spike has prime kit and essential kit, just get the prime kit (the bigger one)
  * Lego spike prime cost around 700sgd in Singapore, maybe more expensive in other shop or location
  * it is under lego education, so you may not find them in lego shops
    * why it is under lego education only, because you need to go through lego app built-in tutorials to build something working, or you basically have a expensive junk
    * you can learn from start to end with lego spike app, and build something useful
    * of course, if you already know other programming language, it is easier to pickup its drag and drop scratch programming.

**some limitation of SPIKE**
  * The SPIKE Prime Hub (the main block) can only play beeps with its speaker.

  * The other Sound Commands play sounds On the Computer/ipad attached (wireless) to the Hub.  
  * it doesn't have dial input module in the prime kit. (other competitor has dial input module)
    * but seems motor can use as dial?
  * the hub module integrates these modules all in itself (means you can't easily to use gyro on hand as detached to drive the hub):
    * gyro
    * beep speaker
    * LED array display
    * battery

  * the light module and color sensor module are all in one module, as color sensor use lighting to enhance detection
    * it not output RGB, only lego block's color sets, but at least it gives brightness value from 0-100
    * light can be also used to output RGB mixed light 0-100 per channel

  * NO mic module for sound detection/input
  * NO temperature module for temperature input
