thanks runie I have an external crystal so that won't be a problem but can i reprogram the flash (not the fuse bits ) without using external crystal?since i have set the fused bits to external crystal from where will it get the clock to reprogram flash?

iam using atmega 32 and i want to use external 16MHZ crystal I have figured out the fuse setting for this as lowbuyte=0xFF and highbyte=0Xc9 what i cannot understand is should i set fuse bits before programming or after programming? because as i have specified external crystal as clock source...

source of voltage is autotransformer and i want to implement an automatic electronic tap changer therefore i need to measure its output voltage(which can go to 300v) to automatically change the taps of transformer to regulate the voltage

Frequency is fixed 50hz

I want to measure ac voltage raging from 60v to 300v using microcontroller i have figured everything else out except how can i use 220v transformer(to step down the voltage to measure) when input is 300v one solution is to use simple resistors based potential divider to attenuate 300v to 220v...

thanks but i need more technical project title which explains its entire feature

we r making a security system which involves face detection tracking of intruder CAN to point out the point of intrusion on GUI and sending message through gsm these r the features of our project but we cannot understand [SIZE="7"]what title should it have to explain it completely in few words?

why electric current flows at speed of light when we know that current is due to the drift velocity of electron which is only few km/s(i think)?

now when i roll the pins the max232 is giving incerted output by using not gate iam getting correct signal any idea why max232 is giving inverted output

so i need to give pin '2'(where signal is coming) to pin 8 or 13 of max 232 which is RS232 inputs instead of 11 or 10 of max 232

iam making a project of serial communication between computer and controller the problem is:- db9 female port is connected to computer and male port is there to connect with max232 now in all circuits i have seen they have written that pin 2 is RTX or receiving pin whereas when i send signal...

thanks that explained

so i went to buy a laptop chrger with rating 19.2v and 3.2A but he gave me a charger with rating 19.2v and 4.2A and said the current rating is not important why is that?

can you elaborate what partially means here and also what kind of safety equipment do you recommend?

Yes i forgot ofcouurse a bridge rectifier
