An interesting stuff….Controlling a LASER Diode and an LED through a capacitive touch using a 80MHz PSoC 5LP introduced from spark fun as FreeSoc2, You can program the I/O of the PSoC in whatever way you desire and a lots more capabilities out of Box with this silicon brick. This board has two processors from cypress that is residing in the Freesoc2 (CY8C5868LTI-LP039 and a CY8C5888AXI-LP096).
Lets get more insight about it here http://sumerulabs.in/blog/2015/07/21/freesoc2-psoc5lp-interfaced-with-a-simple-capacitive-touch-switch-and-laser-pointer/
