What you need

• Arduino Uno
• Breadboard connections
• 5V power supply
• Pull-up resistors
• LEDs

Steps

1. Connect the Arduino to the breadboard.
2. Connect the SN74LS107N pins to the Arduino pins as specified in the datasheet.
3. Check the power supply and common ground.
4. Connect the J and K control pins.
5. Connect the clock pin.
6. Connect an LED as an example of output.
7. Write an Arduino sketch to test the flip-flop.
8. Verify operation with an oscilloscope or multimeter.

Example code

void setup() {
  pinMode(2, OUTPUT); // Output del flip-flop
  pinMode(3, OUTPUT); // Clock
  pinMode(4, OUTPUT); // J
  pinMode(5, OUTPUT); // K
}

void loop() {
  digitalWrite(4, HIGH); // J = 1
  digitalWrite(5, LOW); // K = 0
  digitalWrite(3, HIGH); // Clock = 1
  delay(1000);
  digitalWrite(3, LOW); // Clock = 0
  delay(1000);
}
