Description

The video will show a different SCOREDUINO-A module. Both are electronically same, just the look is different.

The SCOREDUINO-A’ module works as a basic controller for up and down counters or seven-segment display drivers. It has 3 switches for up, down, and reset signals. Up switch increases the count and down switch decreases the count and the reset switch resets the count to zero.

Other features:

  • It has a header for an RF module which makes it capable of receiving control signals from RF remote control.

Scoreduino is programmable like any other Arduinos. It requires an FTDI basic breakout board.

How does it work?

All seven segment display drivers are designed in such a way that this Scoreduino-A’ module fits into the female headers of the drivers. The UP, DOWN and RESET pins of the trigger module connect to pins 5, 4, and 14 respectively of the 74LS192 chip that contributes to up, down, and reset of the count.

Scoreduino works with the following common anode seven segment display drivers. The seven-segment display drivers can be controlled by a Scoreduino Android app or RF remote control or the inbuilt switches.

All the drivers are designed for COMMON ANODE seven-segment displays. It can trigger these drivers:

  1. 1.2 inch RED common anode seven segment display driver– works with 5V-6V. Works with other colors also after changing resistors.
  2. 1.8 inch RED common anode seven segment display driver– works with 5V-6V. Works with other colors all after changing resistors
  3. 2.3 inch RED common anode seven segment display driver– works with 9V. Works with other colors also after changing resistors.
  4. 3 inch RED common anode seven segment display driver– Works with 12V. Works with other colors also after changing resistors.
  5. 4 inch RED common anode seven segment display driver– Works with 12V. Works with other colors also after changing resistors.
  6. 5 inch RED common anode seven segment display driver– Works with 15V. Works with other colors also after changing resistors.
