i cannot reprogram remote firmware....but i need guidance with respect to interrupts in pic18f452...so that i can hold the positive burst signal as long as possible
its ir remote..im guessing its rc5..because its not sony. these kind of remotes sends burst signal to ir sensor...the ir sensor has a digital output..0 or 1. these are interfaced to uC and from the other pic..the output is given to relay..and the output of relay is given to lamp...relay board...
i have intefaced IR sensor instead of a switch for the above circuit. but my output LED is toggling.
1. IR remote as input signal.
2. IR sensor senses the high or low pulse and sends 0 or 1 signal to PIC.
Problem:the output shouldn't toggle when the remote button pressed. it should hold the...
yes these figures are mentioned on the adapters of the devices...

Every solar panel has some losses even if they are receiving sunlight at the peak hours of the day. Generally 20% are...
i live in INDIA...cannot really order items internationally when i m doing projects on my own..its out of my budget...but i can buy in india...any IC you may know of...which may be available on DIGIkey
the problem was...that i didn't connect 30V battery to relay primary coil.....
one more thing...is it necessary to MOSFET? can i use fast switching diode or a transistor?
if i can use then in what configuration i should put it? if im using transistor as in..BJT 2N2222..then how? will it affect...
finally its working :thumbsup:
there is a 470 ohm resistor with a LED...why is it required?
- - - Updated - - -
i mean to assk in the circuit which you sent..there is 470 ohm resistor with a LED at D1..why is it required?
it has a ready made design which comes in a small size...my jammer is quite bigger than that...i just need how to choose a proper VCO IC..what are the criterion to choose a VCO IC...and how to go ahead with it.?
HI...
i have designed jammer circuit...
I'm not going to interfere with signal from tower....but i m just going interfere with signals in which mobiles recieve in my department..the tower is located far away from our department...
IF stage is completed with out of varying frequency from 20k to...
I have a laptop of 19.5V 3.34A
and a receiver of 14V 4.5A..
i need to design a hybrid power supply system using solar panel and a windmill...what could be the specifications i should go for a solar panel and a battery required? also the windmill?
