Touch Sensor for Gun Prop

This is the touch sensor that will be used for our gun prop. It’s easy to build and works well.  I also included the Fritzing file I made for it in case someone else wants to use it.

What you need:

  • 1x 100uF Capacitor
  • 1x 100nF Capacitor
  • 1x 47kΩ Resistor
  • 1x 470Ω Resistor
  • 1x LED
  • 1x 555 Timer Chip
