Rc car with arduino

Hi guys, I'm planning to make an obstacle detection rc car where the rc car will have its power being cut-off/reverse when the sensor detects an obstacle.

If I were to use an Arduino to make this project happen, how should I link the Arduino with the rc car?

Hi everyone! This was my first CNC and 3D printing project.  It is a functional ping pong balls launcher designed to be controlled by an arduino (or any other … Read more

Arduino + Servo + 2 motor driviers = error !

Hello guys ,
so iam new here hope its the right place and im sorry my 1st post is a question  as its my 1st project :D  

ok im doing a project of a robot driven by man with grippers

so basments needs 2 big motors i use for them those drivers

ESC + L293 + Brushless motor

So, i've been having some trouble lately and I can't seem to find a solution on the web. I've managed to controll a brushless motor through and ESC and arduino with PWM. Nothing too dificult. What I need now is a way to controll an inversion of the motor. Like you know, changing two of the wires from the motor makes it turn the other way around.

Arduino servo

Hi

I tried to build a photovore using and arduino and tested it via usb cable,so far so good the system worked as intended as soon as i plug my battery via the dc connector the servo worked but extremly slow why?

Robotic Development Platform

Hello everybody :)

I made this blog to tell you all about my latest project, after my Robotic Arm project has died out a little.

This little thing will be my first actual "robot". The whole idea behind it is that I will have a platform which will be easy to further develop, and thus be awesome to learn new stuff. 

Arduino updates - I hate the new Arduino

When I started using Arduino, V0018 was the latest and greatest. Since then there have been about 7 updates and every time they update, more and more of my code fails to compile.

Since V1.0 and now V1.01 it seems the capital letter "F" cannot be used for a function name. This caused the error:
error: expected unqualified-id before 'reinterpret_cast'

What is an ATMEGA328P

I'm about to start my first robot using Arduino, and I wonder what that long rectangular chip is. I later find out it is called the ATMEGA328P. What is it? Is it like a data storage for the code? If not, what does it do?

Controlling an Arduino with a standard RC transmitter/receiver

 

 

Controlling an Arduino with a standard RC transmitter/receiver

There are many ways to remote control an Arduino, Xbee, RF link, IR…

I decided to try and use something I had laying around and that is common among large group of hobbyist : RC transmitter and receiver pair

Arduino QueueList library limitation

The capacitor across the leads of the sharp did little to rectify K-9's behaviour, so I'm on to the next idea, which is to average the last ten or so readings of the sensor.  The problem is that it seems that Arduino's QueueList library doesn't let you push and pop through different iterations of the main loop-the whole queue is defined each time (so in other words, I'd still have to code a queue by hand if I wanted to average the values read through each iteration of the last ten loops.)  Am I reading that wrong or is there a way around this?
