‫Welcome to the tilt sensor interface demonstration on the basis to development board for the set up
‫we have the basis to board with a with the external breadboards set up on the external breadboard.
‫We have a buzzer that we use to indicate when the breadboard or tilt set switch has been tipped wreathing
‫to 10 Kagome resistors and one electronic slide switch.
‫And the way we're playing a lot trying slides which we haven't seen you can enable or disable the tilt
‫switch sensor.
‫If you port to the right will disable the tilt switch sensor and that's because when we go to the right
‫we're going to go through this 10 cam resistor and pull up to high for go to the left and the tilt switch
‫sensor is not engaged it's going to pull high through the tilt switch center where it is tied to the
‫high.
‫The other end is tied to ground through with a 10K ohm resistor.
‫So when that switch sensor switches or the ball disengage it's going to send out a low signal which
‫when we get a low signal which is coming through our orange wire into the J.
‫P. Mont. port we're then going to send out a P.W. signal on the yellow wire to activate the buzzer.
‫And so in order to demonstrate this first we're going to have our tilt switch sensor so it's disengage
‫we pulled to the right.
‫So right now if we tell our sensor you won't hear anything.
‫Now what you will hear is actually a slight clinking sound and that is the metal balls inside the sensor
‫as it disengage when you tilt the entire breadboard.
‫You'll hear them disengage and reengage.
‫But since we're pulled high to the other side we don't actually see any of that into our input so it's
‫disabled.
‫Now if we enable our tilt switch sensor when we start to tilt or reach a certain point in the buzz
‫and if you go you can keep tilting and you reach a certain point in the body goes away and again it's
‫buzz and Buzz goes away.
‫And that's because when we're tilting those metal balls or rolling and disconnecting from the two pins.
‫So instead of going to pull the high we're now being pulled to ground for the 10k ohm resistor and when
‫we send that zero signal we output our Peter to him as and outputs and activates our buzzer.
‫And so this is kind of a nice little circuit you could use for say a little security system or if you
‫want to indicate hey if something has been moved you know I want to activate the alarm buzzer or anything
‫you can use a circuit like this and that's how you can interface an FPGA with a tilt switch sensor.
‫That is the tilt switch sensor demonstration running on the basis to board.
