In the previous post, I have built my first circuit and able to control the LED light using the gpio command:

Similar control can be done via Scratch, this is the official tutorial:

This is a super simple Scratch script to illustrate this:
In this simple script, when you click the flag icon, it will set the gpio pin 17 (BCM) to 1 to switch on the LED. When you press the spacebar on your keyboard, it will set the gpio pin 17 to 0 to switch off the LED. With this you can incorporate the GPIO control into your own scratch script. Give it a try!
