It is a compact integrated circuit designed to govern a specific operation  in an embedded system.

There are many microcontrollers available, which you choose should depend on:

Technical requirements of the use case, e.g. number of inputs/outputs required

How easy the microcontroller is to programme

How the microcontroller can be powered, e.g. Mains, large/small battery

The range of accessories available and if you can find one appropriate for your use case.]]> 2020-03-01 20:14:31 UTC https://padlet.com/edg1/urlzugi212n4/wish/452643489 edg1 https://padlet.com/edg1/urlzugi212n4/wish/452643490 2020-03-01 20:14:31 UTC https://padlet.com/edg1/urlzugi212n4/wish/452643490 edg1 https://padlet.com/edg1/urlzugi212n4/wish/452643491 2020-03-01 20:14:31 UTC https://padlet.com/edg1/urlzugi212n4/wish/452643491 edg1 https://padlet.com/edg1/urlzugi212n4/wish/452643492 2020-03-01 20:14:31 UTC https://padlet.com/edg1/urlzugi212n4/wish/452643492 edg1 https://padlet.com/edg1/urlzugi212n4/wish/452643493 2020-03-01 20:14:31 UTC https://padlet.com/edg1/urlzugi212n4/wish/452643493 j_perry16 https://padlet.com/edg1/urlzugi212n4/wish/452839358 It is a light source that emits light when a current runs through it.

The colour of the light is determined by the energy required for electrons to cross the band gap. To change the colour you alter the levels of output from the three main lights, red, blue and green.

Examples of buzzers and beepers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.

The most common attachment to them are crocodile switches as they are easily connectible, and the Crumble controller can run 2 motors.

The software to run Crumble is compatible with PC and Mac and Linux. The program is built by connecting command blocks together. Running the program on Crumble is almost instant which allows for rapid experimentation. The Crumble microcontroller can be extended with coloured LEDs, called Sparkles.
