I love this video, it was really helpful in explaining what these I2C pins were for (I've seen them on pinout diagrams before, but didn't know how to use them), and would love for other videos about different protocols. The other thing I always struggle with (though maybe it's just me) is the actual physical wiring of my projects. I can solder things just fine, but I don't own that many components and frequently want to reuse them. So what kind of connectors can I use and which wires (gage, core etc.) go with them? I have failed a few attempts to install wires into those black connectors that you're using to connect the I2C pins to that first port expander. Thanks for the great content!
Thanks for this video Alistair. Looking at the PCF8574 module, I see that there are pull-up resistors on the I2C pins. If one is chaining multiple modules, I think it would be wise to remove the pull-up resistors on all but the first module. Otherwise, all the pull-ups will be in parallel and that could drain too much current. What do you think?
The timing of this video was absolutely perfect. I have been struggling with interfacing NRF24L01 and RC522 with UNO over SPI. Particularly selecting an external power supply to power the NRF and/or RC522. Looking forward to more videos like this in the future.
Thanks you for providing information for intermediates. Past the beginner level, it's get quite hard to find good quality information like your video.
Thanks Nigel Thornberry!

Have you tried using breadboard/s for projects where you want to reuse some components?
Really good explanations saving a bunch of time for beginners and intermediates. Thank you
Absolutely perfect fit for what I may require soon ! Mega thanks!
Can you make a video on esp 32 wich is control by unity editor
Really well explained, thanks

Thank you, this is just what I needed for my current level of working with electronics

Nice!!
Thank You
Love your ideas and projects and a nice easy approach to explaining with great presentations
Another great video, thanks!
