i want a circuit for herein application:
when i turn on the SW ,the relay activated after seconds
but because of low impedance of relay(160 ohms), this circuit did not work
my question is: how i can solve this problem?
is there any high impedance 12V relay that can i use it
I lookfor a pressure sensor that convert pressure to frequency .
The output of the device should be a 50% duty-cycle square wave with a frequency
that is proportional to the absolute pressure of the device.
Which embedded sensor integrated circuit can help me in this way??
I am working on a automation project with PIC.
I prepare driver kit with PIC for controlling two st motors in the XY chart.
My goal is to control a laser beam for cutting any thing possible with above system.
My question is: What power of laser beam i should use for cutting a 3 mm layer of wood...
proteus virtual terminal
I use ISIS 6.9 for simulating a communication between PC and PIC16F877A.
I want send data to PIC by using virtual terminal.
But my problem is ,the virtual terminal just send keyboard ASCII codes to output.
But i must send data like this "0x04 0xF4 0x01 ..." that the...
