r/c car

[lowcurtz]

My Project Is Making Rc Car That Used The Ultrasonic Proximity Sensor To Detect Range Of Object In Front. By The Ranging, It Can Slow The Car When Near To The Object And Move Fast Forward When It Far From The Object In Front. For Info I'm Using Pic16f877a.
Please If U Have Any Ideas. Send Me Schematic Diagram And The Source Code

Thanks...

how about you post up what you have so far that way we can suggest improvements and help you with the bits you struggle with.

do you have the sensors yet, if so which ones - do they come with a driver or do you have to build that too?

How do you plan on controlling the motor?

H-Bridge? or something else?

do please give some help.. i'm just confusing rite now.the project is about the r/c car just move and the PIC control the motor speed( H-bridge) based on the ultrasonic range detector that i'll be put it in front of the r/c car to detect the range of the object.i also want to display the speed of the motor.

If you plan on building a robot it consists of many small steps. Are you familiar with programming the 16F877A? What language do you plan on using? Try David Cook - Robot Room: Robotics, Electronics, and Schematics for some robot ideas.

PS we don't know where near you is, you didn't fill out your location.

Lowcurtz,

I recommend to you, to spend some time looking at David Cook website which is suggested by blueroomelectronics.

Then, take your time and build a plan about all of your project. For example

Mechanical part
a) Build Chassis of the R/C car or buy a ready mad Chassis
b) How the motor will fit in the car if you building a Chassis
c) where You will place the Ultrasonic sensor

Electrical part
a) what kind of motor control I will be using to interface with the PIC and Hbridge
b) What kind of interface will be done between the PIC and the Ultrasonic sensor

Programming part
a) How I will program the motor motion

This is just a start, Try building a plan that you will follow and ask questions specifically to the problems you have. Specific question.
