Yes, you have to use op-amps for some amplification. or you can use ICs lilke AD620....
usually Microcontrollers come with ADC resolution not more than 12 bits like dsPICs30F6011a,
**broken link removed**I suppose your fall time(Red duration) remains same from 0-500Hz and here is hardware solution in my opinion.
use an RC filter having time constant slightly greater then the then fall time...
example:
Red-Duration=1nSec
Let R=100R
C=1nSec/100R= 10uF
hope it helped..
you can use any timer, better if you use which has support for external clock source and which can be incremented during sleep mode(display-off ).
It is nice to emulate RTC in software, however keep in mind;
Timer should be incremented no matter what happens or you lose time setting.
For this...
Yah, thats true....
Theory = you can connect small load to to high current source with no problem as amount of current is 'drawn by' the circuit....
Practice= You need to Limit current drawn from high current (Very Low Impedance source) or you will burn your components.
Demo= Connect your...
Well, regarding your particular application, if you are Ok with these PIC16f628A or PIC16F72 you can use them with mikroC's Soft-I2C Library...
Accuracy in this case epends on the I2C-RTC IC, which you don't have to worry about...

Nop, Its just switching...
great
ok, Blast Op-Amp
Great, So Lets Start with Simplest things that are confusing at the first place...
1. Zenner Selection for Gate...?
I have seen a post by " FvM " that most MOSFETs even Power MOSFETs has a V(GS) limit of 20 Volts Max(though they are more...
Well, those comments are pretty help full...
There are some op-amps that are capable of driving un-limted capacitive load
**broken link removed**
I thought it is possible because I have seen some circuits on some websites for MOSFET Gate Grive, but they are limited to about 20kHz...like (9...
Perhaps, I might not able to express my query correctly....
I have Mosfet Drive ICs like PC923 and TLQ250.... They don't work at 100KHz...
Their are other gate Drivers from LTC, Texas Inst. and Microchip(I had my research),
but their is availability issue and Learning Enthusiasm to build my...
