I am totally new to this world and want to make my first robot Using pic or microcontroller.
I want to make with the parts i have.
Pic12f675,16f877,At89c51,At89c2051,LM339,ultrasonic rangefinding,Lcd,Breadboard ,motors with wheels and many more.
Can any One help me to make my first robo.
Some things you might find
Some things you might find useful are a solderless breadboard, and some basic capacitors and resistors. You may need something to drive the motors (unless you have some hobby servo motors which have built in drivers); transistors can be used to drive them, but you’ll learn more about H-Bridges in time.
And please follow Maxhirez’ advice. The advice given in the Start Here section is invaluable.
Happy Building!
Do you have the ablility to program the either of the PICs?
Once you can answer yes, and, you actually know how to program, then we move on to needing a motor driver.
If you are going to program the PICs in assembly, you are probably pretty close to being on your own. I and many others could muddle through C.
You need a motor driver because you can’t(shouldn’t) drive a motor directly from the microcontroller. Between the major current draw and the voltage spikes when a motor is reversed you could at the very least kill a pin if not the whole micro.
Let us know how the answers to these questions work out.
