Here is a code snippet. Works as expected !    # RGB LED on RPi import RPi.GPIO as GPIO GPIO.setmode(GPIO.BOARD) rPin = 37 gPin = 35 bPin = 33 GPIO.setup(rPin,GPIO.OUT) GPIO.setup(gPin,GPIO.OUT) GPIO.setup(bPin,GPIO.OUT) GPIO.output(rPin, 1 )   # Red GPIO.output(rPin, 0 )   # Green GPIO.output(gPin, 1 )   # Green

Using a Raspberry Pi 4 A blinking LED is the Hello World for physical computing.  Raspberry OS allows many ways to do this.  Here are 3 ways to Blink an LED from the RPi 4. Figure 1: Blinking LED wiring on RPi 4 (from Tutorial 3 below) (gpiozero)   Blinking LED Raspberry Pi Tutorial 1 This tutorial is great not just for blinking LED but also intro to "Physical Computing": Getting started with Breadboard. Resistor labeling code diagram included. Using a multimeter to test power provided by the RPi Understanding basic circuit first not controlled, then controlled by the RPi. Using Python from a command window, testing basics 1 line at a time. Intro to import gpiozero , a pre-installed on RPi library with import for basic needs like LEDs and buttons. from gpiozero import LED import time led = LED(17)  # GPIO17 led.on while True:      led.toggle()     time.sleep(1)      (GPIO)  Bl in king LED Raspberry Pi Tutorial 2 Alte...

Desired: A Raspberry Pi set-up that will fit in my purse. Parts Raspberry Pi 3 & Power supply Raspberry Pi 7" Touch Screen LCD Raspberry pi 7-inch lcd touch screen case , white or black New Raspberry Pi 7" Touch Screen LCD - Assembly Good video because it shows how to stablize the screen ribbon and close up of the pins to share power. A Raspberry Pi  Trouble Shooting  page is provided, but generally check all connections if not working. Touch Screen Case set-up Raspberry pi 7-inch lcd touch screen case , white Initially the image in this case is upside down (due to RPi firmware update). To change add:  lcd_rotate=2  to  /boot/config.txt using and your favorite editor  or sudo /bin/su -c "echo 'lcd_rotate=2' >> /boot/config.txt" Note: Some suggest using display_rotate , but the following  from Element14 forum explains  why lcd_rotate is better: "Don't use the documented display_rotate , it performs a pe...
