THE PROJECT GOAL : is to make a smile on our babies faces and their parents :) ..
Our instructable depends on homemade Resistive Touch sensors..
if we touch our touch sensors that exist at both sides of the screen laughing baby sound will be play, if we touch the sensor was situated on the upper middle of the screen a sleep tune will be play then our computer will be Hibernated after 10 seconds and if we touch the upper right corner Facebook website will be opened by our virtual Browser ( Google Chrome, Firefox, etc..) .
we can add any feature to our application as we need.
Step 1: What's You Need ?
You need :
you can use wires from PC power supply to make sensors and you can use jumpers on Bread Board "i don't have jumpers so i use breadboard wires shown in Pics" .
you can buy it from any electronics store :) .
we are need two batteries " (5volts) and small battery it's value between 0.5--2 volt ".
note: Instead of 5v battery i use 9v volts battery with 7805 voltage regulator no problem :)
4. four Resistors (6.8MOhm).
5. 2 ICs LM358 : we use it to make a sensor "when the drop voltage on IN(+) be more than thread voltage on IN(-) ,the output of Comparator is going to be nearly 3.3 volts" .
6.four capacitors(100nF) :
we use it to solve button debouncing problem.
7.Tiva C TM4C1294:
(you can use Arduino without any Problem :) ).
we use a cloth to make the project form beautiful and to disappear the wires :) .
we use it to check the homemade resistors is works or not and so on ..
10. Cutter wires .
11.Medical adhesive tape :) .
12.Makeup cotton : it has a wonderful shape :)) .
