Good Evening Bill, and thank you for having me on your forum.

I really enjoyed your videos on Shift Registers and TCA9548A I2C MUX. Very informative indeed!

I had an idea for new video content. I know you just released the "Shift Register" video and I thought an interesting extension of that would be:

1. Covering different options for GPIO expansion as far as the different chips/modules available such as the CD74HC4067 (16CH Analog MUX), MCP23017 (I2C MUX), SX1509 (I2C MUX), MCP23008 (I2C).

2. Show the output capabilities/ limitations of these can do real work with relay modules, mosfets, etc..

3. Show the input capabilities/limitations of these devices, how they can be used with Interrupts.

I felt this would be very practical subject matter that many hobbyists can enjoy that have interests in robotics and IOT projects.

Thanks for your consideration.

Warm Regards

Actually this may be the quickest accepted content suggestion to date, only because it has already been on my list for a few weeks!

I was planning a video on using the MCP23008, which as you stated is an I2C port expander.

So content accepted!

Good Afternoon Bill,

Another very interesting chip on this list is the CD74HC4067 (16CH Analog MUX)

I think this one is worth investigating because you can input/output many analog signals using MCU's that may have limited onboard analog IO, ie.. ESP8266...

Thank you for your time and consideration,
