Microcontollers have input ports and output ports. You can connect lots of different and interesting sensors to the inputs, like switches, pressure sensors, temperature, motion detection etc. To the outputs you can connect LEDs (Lights), displays, motors, speakers and lots more. You write a small program to tell the microcontroller what you would like to do with the different devices you have connected to the microcontroller.

You will find microcontrollers everywhere!! Here are a few places you will find them:

  • Household appliances like microwave ovens, dishwashers, washing machines, remote controls etc
  • Cars
  • Medical devices
  • Toys

There are thousands of projects you can build with microcontrollers. In the Clubhouse we play with the Arduino and MakeyMakey. We also create E-Textiles using the Lilypad which is a microcontroller you sew onto fabric. More about E-Textiles further down…..
