Hello Everyone!
Guitar pedals and music effects are very interesting to experiment with, so I decided to come up with something new and original. Using minimum possible components I made a circuit that simply breaks and rejoins the connection between the guitar and the amp. But thats not the catch,
This pedal can be controlled without coming in contact with the pedal. 
Weird, right?
The setup uses an ultrasonic sensor (Popularly, used for obstacle avoidance in robots) to calculate the distance from the pedal, and activate the effect accordingly. Also the closer you move towards the pedal, the more shallower the effect gets. 
Well, if I've got your attention and your head is bubbling with ideas,  here is , how I made it!-

Step 1- Watch the video-

Step 2- Get the parts-
1. An Arduino ( Uno or Nano) ( a clone would also do the trick)
2. A single channel relay (an electro-mechanical switch)
3. (1/4 inch mono sockets) x2
4. Ultrasonic sensor module (HC S…
