Have you ever heard the phrase “it’s not rocket science”? Rocket science is a difficult field of study. While you won’t have an actual rocket to launch, in this project you’ll make a program that, when the button is pushed, turns on a light, just like a rocket launch initiator that illuminates a series of lights in preparation for liftoff.
Using an Arduino for the first time can be overwhelming. You might be looking at this tiny device and wondering “what the heck is going on here!?” Today's post is about helping you understand your Arduino and get set up. This series of posts will guide you through your journey with Arduino with easy-to-follow projects to help you get the basics down.
Have you ever wondered how planes are able to see each other at night? In addition to their RADAR, they also use strobe lights. In this simple introductory project, you’ll learn to program an LED to blink on and off like the strobe light of an airplane.
So...which Raspberry Pi 4 RAM size do I have?
If your Raspberry Pi is already up and running, you can easily check for the memory size within the OS. However, if your Raspberry Pi is sitting in front of you right now, you can simply look at the marking on the RAM chip. Refer to the picture below (2GB version shown):
At the time of writing, the marking code is as follows:
1GB - 4HBMGCJ
2GB - D9WHZ
4GB - D9WHV
8GB - D9ZCL
