Hi all,
I have made a custom board with Atmega328P SMD IC and now I am having a problem flashing it. I have flashed multiple chips like these earlier, however this time I am having a hard time figuring out the issue.
I am using Arduino UNO as an ISP programmer to burn bootloader but getting responses like Attempt 1 of 10 - stk500() is not responding etc., like that. I need some help regarding this issue.
Any kind of help will be greatly appreciated. Please ask me for any additional information that I might have not mentioned in this post.
Thanks in advance.

I have been facing this problem recently while I run the program the output terminal just shows scanned text and the android virtual device is not opening. I have reinstalled the SDK but the problem still persist.!

Hi, I was looking for a reliable carbon monoxide sensor, I tried the MQ7 sensor, but it has a preheat time of 48 hours and a sensitivity range from 20ppm-2000ppm, and my application requires 1ppm to 1000ppm. let me know if anyone working with a similar sensor or use case!
Update: Found that SPEC 3SP_CO_1000 Package 110-102 have 0 to 1,000 ppm sensitivity range and < 100 ppb reseultion, if anyone worked with the sensor let me know. Thanks.

@milanvarghese No, the battery comes into the play only if there is no power from the solar cell. It's like inverters in our home. They activate only if main power is gone, rest of the time they keep charging. similarly here the direct power will be coming from the solar cell, only if the solar cell can't produce enough voltage battery comes into the loop and starts providing voltage to our circuit.
