hello! my name is klv_sai

I am working on one project where we used Arduino as automation platform, there I met with a problem in programming and am unable to get out of it. please help me in resolving it...

the problem is in looping I used "else if" looping but it is not working like..

I wrote program as below:

if (AnalogValue>459)
{
do statement 1;
}

else if (220<AnalogValue<=459)
{
do statement 2;
}
else if (123<AnalogVlaue<=220)
{
do statement 3;
}
.
.
.
else
do statement n;

but the program is not running well it is not going through all the condition for every analog value lessthan 459 it is going to do statement 2;even though the analog value is less than 220

can you please show me a way to solve it...

I can see what you're trying to do with statements like

if (220 < AnalogValue <= 459 )

but C doesn't work that way.

You need something more like this:

if (220 < AnalogValue && AnalogValue <= 459)
