• 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.
  • ref: https://www.cs2n.org/u/mp/badge_pages/1432
• 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
