Thanks.. am i correct that whenever there is light the photodiode will convert it to voltage output and would then input to my LM11C.. Could you please clarify if i am correct. Also, how does the LM10 help offset and regulate the input voltage? thanks!
Hi could somebody please explain this circuit. I do not know how to where to measure an output from this circuit by simulating it to multisim, where can i get data. could any body please tell me how. Thanks!
This is a brief explanation of the circuit:
This logging circuit is adapted to a...
Hi, I would like to know the minimum amount of current needed to turn on the AD620 instrumentation amplifier. I tried looking at the data sheet, however, i do not know if what i saw is correct. The current i've found is 0.5 nA is that correct? please help.. thanks!
Hi, i am having problems with the output pins of my PIC16F877A microcontroller because whenever i turn an output pin on there is less than 5 Volts found in that certain pin (i.e. RB0). I need the 5 volts to drive my relay also using a relay driver. I saw from my voltmeter that only 4 to 3 volts...
Hi, I'm trying to light LED's using pic microcontroller and i wanted to use the switch statement to do so. My program starts with an analog input voltage coming from RA0 which i would use as an ADC terminal. I wanted that for some voltage inputs the LED's connected to RB0 - RB6 would light up...
what would happen to the microcontroller if the configuration bits are not specified? will it work or not? Also, what would then be the default set up for the config bits?
Hi, how do i input the code for the configuration bits in C code using Hi tech C compiler and MPLAB. If you have a snippet of code about please do post it here. thank you very much!
Hi, i'm trying to make a microcontroller work using a 16Mhz crystal oscillator connected with 2 22pF capacitors grounded. However, I was having problems with the crystal oscillator because it only works when i touch the damn thing.. Is there a problem with the circuit configration or the...
Hi can somebody show me a C program for a digital weighing scale.. I tried to program one but i wasn't able to receive the result that i expect... here is my code
#include <htc.h>
#include <pic16f877a.h>
#include "delay.c"
#define _XTAL_FREQ 16000000
unsigned int ADCRead(unsigned char channel)...
My load cell has a maximum weight of 3kg and its resistor values are all 750 ohms. I've tried to put an excitation voltage of 5 volts and the 2.40 something output was the result. I dont know the voltage sensitivity of the loadcell because there were no data sheets about it. I'll try to reduce...
I have set my gain first to 333 then i got 2.40 something volts output. However, this voltage output is very small for my low resolution ADC of 1024 my results would then be very inaccurate.. I tried to increase the gain to 9999 by using a 5 ohm resistor but the ouput still wasn't enough to...
Question, what do i connect to the negative voltage input(-Vin pin) on the INA125 from the AD620? can i just use an op amp to further amplify the signal and what op amp can i use? thanks!
