One more way is using zener diode to step voltage from 12V to 5V. As shown in this figure
But it can have some noisy output(A surge in voltage sometimes) which would not be good for Microcontroller.
So, It is better to use voltage regulator like LM78series.Just take care of i/p & o/p capacitors...
When I started using interrupts method, it was horrible because Interrupts increase risk by being non-synchronous(mostly delaying) with the rest of the program and it took time to understand how to use interrupt. You can remove this unsync part, but it adds more code, ram usage, and time to...
Take little help from and write code.

or install MPLAB X IDE libraries there u can find sample codes. edit these code according to your project work.
It will be better if you can post your input and output waveform.As of what i understood from problem description i think you want to reduce the AC voltage,well in that case Use Electrolytic Capacitors instead of Resistors for dividing voltage.
Hello Everyone,I am controlling a very high load(Air condition type) using a realy switch.But Relay get stuck after continuous operating(ON/OFF) of the switch.
Possible reason:- As high load gets ON.It takes surge current almost 6-7 times of its normal rating.Like a 6A AC takes 60 Amp surge...
Hello everyone,
My name is Vikram Garhwal. I work for Orvito Technologies. we are US based company headquartered in Massachusetts, USA, Orvito which works in wireless automation and security surveillance products . We are looking for PCB Design Engineer(5+ experience) at our...
I was not able to understand this part ""I've tried to charge until full, after a full battery save mode turned on the laptop and left to power off , and then turned on again mode normally , but that does not work...""...............Anyway now its clear to me as you edited it.... :-)
Update...
Filter :- We use it for allowing only desired part of signal.
Controller :- We use it for reducing error and making system stable.
So filter can be used at controller if it fulfilling the requirements.
Example :- A noisy signal..if you use a noise removal filter,one can get the less noisy...
Yeah it is absolutely correct..
Half Intensity refers to the viewing angle rating as specified by the LED manufacturer. This simply states that at X degrees the LED intensity will be ½ as intense as it would be at 0 degrees. Our high-brightness & high-contrast design allows the actual visible...
