AT Universal Button Vibration Attachment

Hi we are the group "Dealing Mayhem" , our project is an attachment for universal buttons aimed towards people that struggle with fine motor skills, visual impairment, and also hearing impairment. This attachment is able to vibrate when detecting a sound in its radius. By vibrating, people with these types of disabilities are able to locate their universal button, or really anything able to be attached to the design. This works through technology such as Arduino and sound sensors

After laying out all the hardware, start by wiring the Arduino like the diagram above ^

Assembling all the parts of the hardware, the Arduino, the breadboard, the relay module, and the sound sensor should be all be connected through the jump wires.

While finishing the wiring and Arduino assembly, plug the Arduino board into your computer running Arduino IDE 2.0 using the USB 2.0 cable type a/b.

After completing the setup of Arduino IDE 2.0 input the code in the file below ↓

When done copying and pasting the code into the Arduino program press the upload button to upload it into the Arduino assembly.

After the code is finished uploading into the Arduino assembly, unplug the Arduino from the computer and remove the USB cable. From here plug in the 9V battery to the Arduino using the battery clip connecter

When the Arduino is assembled and all programed, test the sound sensor by making a subtle noise. The pager motor should vibrate for a couple of seconds and stop. With the little knob on the sound sensor module, you are able to adjust the sensitivity. Play around with the knob to adjust it to what's suited for your living space, making sure not to turn it too much, and too far from return.

Finally, after the Arduino assembly is fully completed, set up the Onshape modeling software to print out the button attachment box to hold all the Arduino and wiring. By downloading the file below ↓ Press the import button to upload the model of the box all ready to be printed. If not able to 3D print, you are able to take a suitable cup to set your button on, and drill a hole in it.

Place the Arduino Assembly into the box carefully making sure to not ruin the wiring. Tape/attach the pager motor against the wall of the box to increase the force of vibration.

Assemble everything and have all loose wires exit through the hole of the box.

After everything is finally completed, test the mechanisms of the device vnd make sure everything is working properly. Try to set it up in your house or the desired location and try to enter that place with noise. If everything was made well and all steps were followed. The bibrating button attachment should work exceptionally.
