Week 11: Segment 1: USe of External Interrupts with the Touch PAd

This segment focuses on external interrupts for the detection of events that occur sparsely and randomly such as a touch pad or button event.

Goals:

• Understand the use of external interrupts that are triggered by pin events.
• Learn to use the touch pad that came with the Arduino Kit.

In-Class Project:

• Set up the touchpad and operate it using an external interrupt
• Combine the touch pad with other devices such as the servo or an LED display.
• Use external interrupts for reading out a button.

Materials for this segment:

• Watch the video on the right 
  
• Arduino sketch featured in the video (see link below video).
• The interrupt page at Arduino.cc

Use this Arduino sketch for an improved set-up that uses Arduino digital pins 3 and 4 to power the touch pad. This allows to connect the touchpad directly to the Arduino headers without the need for jumpers:
