Target : Display a counter from 0 to 9. The counter increments every second.
How : The Arduino provided BCD number to display.The decoder is connected to the Arduino and the 7 segment LED display is connected to the BCD decoder 74HC4511.
Wiring : Use the same wiring of Class07. Connect just the inputs of the decoder to 4 digital outputs from the Arduino.
Soft : Make a counter,
display characters 0 to 9. You can use the function bitRead()
Components : 74HC4511, 7 segment Display, resistor 220 Ohms
