Raspberry Pi #2 - LED Blink in Python - Digital GPIO

Raspberry Pi #2 - LED Blink in Python - Digital GPIO

In the second tutorial, I walk you through the use of the GPIO port on the Raspberry Pi. This is done through Python on the Raspbian OS. Feel free to ask questions if anything is unclear.

great tuturial, just saying though, it would be great if u could leave a diagram 2 show where the pins go on the breadboard

Great tutorial. but I have one question? is there a way to use the same programming method that you used, to control some form of switch, so that an externally powered LED lighting could be blinked/operated?

how do you conning LED lights with a guessing game program in python. I'm a beginner

Hello

1. There are many devices for HDMI recording like Avermedia family, internal cards for desktop PC etc. Recording monitor with camera is really bad, it's 21th century now :)
2. But why you decided going this way? I think it's more comfortable for people working from PC with Pi, so maybe you can introduce for begginers the way how to initiate Pi just with power and Lan, and how to connect with Putty. That will be also more easy for you to capture on video.
3. If you do not have it, at least tell in video, that common versions of Pi A+ and B+ has 40 pin GPIO, of course there is new Pi 2, but the only change is the new quad core CPU and 1 GB of RAM.
4. Please note in next video limitations about Pi's GPIO, if I remember correctly output current is more limited than Arduino, 16 mA per pin with max 51 mA for all pins combined.
5. On some of yours windows desktop recordings I see for few seconds some artefacts on screen on every major picture change. Try change method how you recording windows desktop, I do not have any advice, but I'm sure there is software to record flawless videos.
5. Change the microphone what you are using for record voice for windows captures, the current one has bad quality and low volume, even compared to your camera microphone. During mastering put volumes of both mics to same level.
6. That's probably just me, but in this video when you capturing the Pi with breadboard I felt little dizzy :) it was because you filmed it with bigger angle than 90 degrees ( between the desk and camera), what is unnatural for human brain.

thank you and good luck

hey hey! do you know how to integrate it with ALLJOYN?

i get an error saying there is no model as RPI.GPIO
plz help
