Re: Proteus design of arduino pro mini with servo motor

.the PWM signal from the pro mini IC ATMEGA-328 has to send to servo motor through serial communication.Ihvae two questions . 1)how PWM signal value is 0-255 ?if it is that,that data transmitted is 8-bit so it makes 256 combinations.it is alright.i agree!! but why when we connect the serial port we...

C Program to Interface Keypad Using 8051

I wanna make a program in c which will scan the keypad and send the result to first serial port.
P1.0 to P1.3 stands for columns and P2.0 to P2.3 stands for rows. Serial port should have a band 56k, 8 bit and 1 stop bit.
Help me do + understand it.. Thanx
A beginner is here..

proteus simulation: serial communication using two 8051

hi i am trying to do a proteus simulation of serial communication of two microcontrollers as shown in the attachment but unable to do it..as the optocoupler connected to it does not work and there is no sign of signal in the TxD pin and the led glows automatically in simulation. the logic i want to ...

Led not blinking using 8051!

Hey guys! I setup a breadboard circuit to do the basic single led blinking test using a AT89C52 chip. However, I do not get any blinking, it just lights up until power is stopped. I had only enabled a single bit for port0.0. The code is below. However, the led lights up even if I connect it to any o...

Problem with changing the sheet size in Proteus

I am using Proteus to simulate my circuits.

I want to simulate a circuit that is bigger then the normal working sheet, and when I try to change the sheet size to A3 for example the program closes.

did anybody encounter this problem?

thanks...
