Seven Segments Arduino Bt Ctr APK

Learn with this application: Seven Segments Arduino Ctr Bt works as a seven-segment display common cathode with all its features.

Functions:
The main screen shows a seven segment display and its representation "A", "B", "C", "D", "E", "F", "G";
Code: Converting binary to decimal (BCD), as an example decimal digit "2" = Binary: "1101101"
Arduino: corresponding digital pins (4, 5, 6, 7, 8, 9 and 10) for each segment of the display.

Start Button: Starts a score of 0 (zero) to 9 (nine) of forming a loop;
Stop button: To count showing the last valid number;
Reset button: To count returning to the number 0 (zero);
Inc ++ button: Increments a digit to count;
Dec-- button: Decreases one digit to count;
Seven Seg button: Shows the seven-segment display has the representation
segments ("A", "B", "C", "D", "E", "F", "G" and "DP");
Mon Test Button: Displays an animation test of seven-segment display represented by
segments ("A", "B", "C", "D", "E", "F", "G" and "DP") moving every 500ms;
Shematic button: Opens the wiring diagram of the Arduino uno r3 with the Bluetooth module and the seven segment display of common cathode.

Data transmission via Bluetooth:

Connect the bluetooth smartphone and Application Seven Segments Arduino Bt Ctr, connect the Connect button;
From this moment all the above functions like Start, Inc. ++, Mon Test and others will be transmitted
for the Arduino board with bluetooth and visualized in real time in the seven segment display module, becoming a learning experience and very interesting.

Come example to show the number 1, simply activate the B and C segments, and to show the number 3, the A, B, C, D and G segments, and so on.

Connecting the Bluetooth module uses the Arduino digital pins 2 and 3 for serial communication (rx - tx) plus the GND and VCC to power; View full wiring diagram on blogger:

Connecting the Display deigitais uses the Arduino pins as follows:

Pin 4 of the Arduino ====> pin segment A
Arduino pin 5 ====> pin segment B
Pin 6 of the Arduino ====> pin segment C
Pin 7 of the Arduino ====> pin D segment
Arduino pin 8 ====> pin segment E
Pin 9 of Arduino ====> pin segment F
Pin 10 of the Arduino ====> pin segment G
Pin 11 of the Arduino ====> pin segment POINT (DP Dot Point)
GND pin of the Arduino => Pin 3 (cc common cathode) of the display.

Important use of resistors 220 ohms for each pin, necessary to limit the current of 20mA segments thereby preventing burning of the display.
