GOOD VIDEO ,, LOOKED AT SEVERAL VIDEOS . THIS ONE WAS TO THE POINT.. FAIRLY SMALL CHANEL BUT GOOD

I followed your steps and succeed to light the led.Thank you so much. esp-01s 3v3 to uno 3v3,esp-01s gnd to uno gnd,esp-01s en to 3v3,esp-01s rx to uno tx,esp-01s tx to uno tx,esp-01s io0 to gnd,esp-01s io2 connected led to gnd.

Thank you❤

What can you use as an antenna if you don't have one?

You used max30100, not max30102, which is definitely different.

contrast is the kay issue

Thank you for this straight forward video without any unnecessary talking around. It really helped me to get the LED blinking. Thanks.

instead of int delayTime = 1000000; int stps=1000, use int delayTime = 1000; int stps=1000

Device signature = 0x000000 its not detecting the device. but i can run code on the nano separately. I can not flash the nano for other uses. oh well

great advice so subscribed

You are awesome!!😄

Thanks for this helpful video. Would this test be compatible with ESP32S3 Wroom1 dev board? I have uploaded the sketch and can see the LED control page but the board LED will not switch on and off using buttons.

Don't use solder on Lithium batteries, The heat isn't good for them. Only use a spot welder.

Nice and easy

I have not default password why?

thanku very much🙂

Good stuff. Thanks.

Awasome it works

Hi, I would really appreciate if you could reply. I connected this gsm 900 A with antenna to 5V 2A external power source as you have shown and tried it with different sims, the light still keeps blinking very fast. What can I do??

Sir can you pls share full code and circuit diagram..pls sir

bro is this cathode or anode display

Can I use SMB arduino UNO ?😅

Bro code and diagram not opening

Can we use 12V-1amp adapter?

Schematic ??

Tried it and it works Thanks Big like

I'm trying to use a sim900a but after I insert a sim card and power it, it doesn't connect to a network. It just keeps blinking every 1 second for hours

Thankuu..... Bhai very very very much. I was looking for this from 1000 of hours thanks to youtube too, that it recommended me your video. You are doing very good work sir.
