The UNO has a 16MHz resonator. What runs in it has to be set up for 16MHz.So basically if I set up the chip using 8Mhz internal oscillator and then take the chip down from breadboard and put in on uno..and burn a code..so in that case it wont work right?? so i have to set up clock speed of 16Mhz iam guessing it while iam bootoading it.
the FINAL MAIN POINT I WANT to clear is the FTDI cable really required as mentioned by nick at the end for programming a sketch, once the bootloading is done cant i simply take my chip out of breadboard and connect in on uno burn and compile the code whatever code might be( according to circuit i will be making)..i and iam good to go. Wont that work, I know Iam asking too many questions but if you can answer the final point..that would really helpful..because I wil be going to shop today to purchase the equipments. Is FTDI cable required for programming a sketch???thanks a lot
ok I just read your post...but guess what i bought all the devices except teh FTDI connector..did exactly as nick mentioned, I had to add the external crystal and pF capacitors, so i choose the 16Mhz crystal, after the booloading was done..I didnt know what to do..so just for trying I loaded in on uno..burned a random code..i think it was a lighting two leds..with differnet delays..it worked on uno.tried on breadboard and guess what it worked on breadboard as well.. .. i gave 5V from uno directlyso i guess its not that difficult afterall..tomorrow I will be setting 8Mhz internal oscillator and try with another blank chip... so i guess this part is complete...the next part would be to use power saving techniques in the software part..I will try it myself first..then I will again revert back to guys if some help is required..thanks a lot guys..
..no signal is sending,

One big power save is don't run a lot faster than you need. After that there are sleep modes and powering down parts of the chip you don't use. Though I didn't memorize those, I think that ADC is one. All parts on is like a house with lights in every room on. Try running your sketch at 1 MHz for starts, just to see how well it keeps up.
Assuming it is still "not working" can you please run my Chip Detector sketch on a spare Uno (I presume you have) and copy and paste the output here (use code tags please).
I tried that but i dont think its the most efficient power saving technique, because my barebone chip i had made earlier WITH THE VOLTAGE REGULATOR..the 9V battery only lasted for 4days..despite me waking up the chip once in 2hours..transmit data and go back to sleep. LM7805 regulator as it was consuming a lot of current and this is what brought me here.
