DIGITAL APPLICATION
            -After programing the ATTINY45 board with a light sensor, i used PROCESSING to process a graphical application that changes the opacity of this
circle according to the light intensity it's receiving from the sensor on the board.
 


-The first script as shown in the picture worked well although
the Raw readings were varying but not according to the sensor.
- I tried changing the cable and unplugging it more than once
BUT the problem was at the language the  PROCESSING is
receiving from the board which was in STRING according to the
ARDUINO script.

           -By declaring the revived data to be in string (String stringReceived = "";), the script run and it was sensitive to the sensor but the circle didn't appear
 at all this means that the data imported by sensor is larger than the float value range,

    -I had to MAP the value i'm getting from the sensor. The mapping
command works between the 0 and 255 according to the float range
and since my sensor input values are above 900 but below 1023 so
the rage was (value received, 900 (min), 1023 (maximum), 0 (min
float value, 266 (max float value);
