Here, in the picture attached, I've simulated a constant current source using an NPN transistor, TIP series. My task is to vary the R2 resistor and measuring the current change. This picture holds the info for a certain value, R2=50k. But the current, Ic is still constant. even at that value...
ustom circle copper fill in ares-proteus
I need to copper fill the portion in between the two circles. I've tried zone select mode, but it doesn't work efficiently as I need. Is there any option to do it?
I'm struggling with recording heartbeat sound of 20-180 Hz. I've tried several android apps to record with stethoscope integrated with condenser microphone. But it records low sounds from far away, but not heartbeat. So, what can I do now? Would I try to make an audio amplifier to amplify it...
If you use universal remote,you should know each button's pulse code. You can find in using manchester coding.
There is another way,you can use UART protocol for uC to uC communication. Use Transmitter IR on Tx of remote uC.Send a character,say 'x' by UART_write function. Set IR receiver on...
You can do it by several ways.How many switch do you need to control? And what kind of remote,the universal one or something self-made? Analyzing these things you should choice your protocol. Like UART or just switching it through logic.
At first,try yourself. If failed,then post the code or...
I've done UART communication,with virtual serial port driver.
Hope it would be helpful to you the newbeez to microcontroller.
Here is the sample code in Mikro c and simulated in ISIS.
:)
Yes.
heartbeat axis actually shows equivalent voltage of heartbeat.
Yes,it is an audio signal,I pulled it down with a 100 k resistor before sampling to thr Uc so that it shows zero level while there is no sound.

I specified bandpass freq,but there was no option for roll of...
The software suggested me 12th order,nothing else. The waveform is plotted realtime on C#. Uc sends data after every 20ms.Baud rate is 9600.
I am also confused is it reasonable or not...
Hi everyone,
I am working with my project of developing a heartbeat monitoring device. I've built a circuit that gives me output quite well, but there is noise. FIltering it out I wanna design a bandpass filter of range about 60-600 Hz. I've tried in Filterpro designing software, it gave me...
I've just solved the problem. :)
Problem was,I had't made the analog B port digital.
Thank you vary much sir :)

TRISD=0xFF; // Configure PortD as output port
For output it should be TRISD=0;
I'm tried using Mikro C 4.15 and 6.00
But still no output.... :(

This is my modified code.But still there is no output..... :(
void main()
{
TRISD=0; // Configure PortD as output port
portd=0;

INTCON=0b10010000;

Thanks for reply :)
Sir,isn't it necessary to select the initial state of PORTB ?
I just want to make state "HIGH" of PORTC by external interrupt on RB0. My logic was,when PORTB=1,interrupt will occur confirming INT0IE && INT0IF=1.
I'm little confused when I press PORTB.f0,does it automatically...
