Python Programming
1. Change directory:
cd/home/pi/IDUINO_SuperKit_Python_code_for_RaspberryPi/
2. Run:
sudo python 10_74HC595_LED.py
You should see eight LEDs blinking regularly.
Here, three Raspberry Pi
®
GPIOs are used to separately control eight LEDs based on the 74HC595. The
74HC595 has another powerful function: cascade. With cascade, you can use a microprocessor like three
Raspberry Pi
®
IOs to control more peripherals.
