Thank you so much for sharing... I have just assembled your scheme "MPPT 3.0 with arduino nano", but suddenly cut off the GND from 3rd pin of irfZ44s => so that the arduino very hot at 328P chip, btw all 3 leds: RX-TX-PWR are ON => how to fix this? Thank!
A LED in the the forward bias has zero resistance. If you don't add a resistor the total resistance through the LED will be zero. This will for even a small voltage drive a large current through the LED and short-circuit and burn everything. You'll have to buy a new Arduino. Be careful.
Excellent video. I was looking at this kind of solution a while ago. You just made it !
What is the maximum sample rate you can reliably toggle a multiplexed pin at?
Beautiful project
good work bro 💪 👏
Hi i need to know how to control Analog pins and change the value of the pin using analog mux. Is there possibility??
Is it possible to add a third CD4051 to the arduino nano to achieve 24 analog inputs?
This is truly helpful 👍🏻
Nice info, thanks for sharing it:)
Thanks a lot sir 😊
You could use PCF8574 for digital inputs and autputs.

Great video. But what are the resistors for?
LED'S

hi sir can u explain the code.. i dont quite understand how to use the extended digital and i/o pin in the example.. great video sir
Good day Sir
Big big help
Nice
Sir over load and uner voltage protection circuit please
Excellant.....
That's a good video. Very helpful. Can we get some code example?
In the description bro
drive.google.com/file/d/1vaierSpSrTzODxC-LPX1NEW12ocdoiWQ/view?usp=sharing
will this work with toggle switches or not?
yes it will
Masha Allah
Nice, too bad you didn't explain how to cascade the chips though...
I will soon explain it bro
Thank you
Shift registers are either useless or make programming way more complex for outputs other than LEDs
Best Bhai 1000$
thanx bhai
Do you sale this pcb
Please sir arduino uno video 4 channel relay remote kit program
bro arduino k saath bana chuka hu ma ab attinty85 pe bana ya ha jald video ajai gi us ki
th-cam.com/video/dgaa0I_RXNQ/w-d-xo.html ye video ha 4 channel ki
