Experimental Procedures

Step 1: Build the circuit. If you want to take out the chip from the breadboard, DO NOT pull

it in one direction forcefully, for fear that the pins on it may be bent and you may get hurt.

Try to use a sharp tool to cross the notch of the breadboard to remove the chip.

For C language users:

Step 2: Get into the folder of the code.

cd /home/pi/SunFounder_Super_Kit_V3.0_for_Raspberry_Pi/C

Step 3: Compile

make 13_74HC595_LED

Step 4: Run the executable file above.

sudo ./13_74HC595_LED

Code Explanation

unsigned char LED[8] = {0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80}; // This array is to

store the output values of Q0-Q7. For example, 0x01 in binary format is 0000 0001, thus

Q7 Q6 Q5 Q4 Q3 Q2 Q1 Q0 are 0 0 0 0 0 0 0 1 respectively, that is Q0=1, and the LED

connected to Q0 will light up. Thus we can light up the eight LEDs separately in this

way.

void pulse(int pin){ // generate a rising edge

digitalWrite(pin, 0);

digitalWrite(pin, 1);

}

void SIPO(unsigned char byte){ // Assign the char byte to the SDI bit by bit

int i;
