Controlling powerful motors

Hello guys,


I want to control a powerful motor not like the ones used (servo motor) I need something of the ones which work on 110\220


I am not sure if it is possible using picaxe, if so is there any tutorial or has anyone done this before?


Obvioiusly it should be powered externally and controlled by picaxe


If this is not possible what can the strongest servomotor provide me? Can it for example to move the steering wheel of a car?



Attiny 2313/4313 servo driver

Hello everyone!

Attiny85/45s are great for small projects because nearly all pins can be used to drive servos simultaneously.

However 5 servos are nice but not enough. I found out that I have bought some Attiny4313s a while ago. They 20-pin chips that can be programmed via arduino. Now I am wondering how many servos it can control. There already are different approaches:

theory vs. soldering

Well...my robot is far from being able to be presented.

In fact I try to build/solder some parts on my own, which seems to be more challenging than expected. Actually I´m soldering a h bridge with its controller based on oddbots h bridge - without the current sensing part - and I just hat to face, that it doesnt work. I guess its not due to oddbots design, but to my soldering skills and or adapting to a simple board design, since I solder though-hole.

I hope I can figure out the problem soon...

wild thumper + wild thumper motor controller how do i let it start driving?


im new t building robots and i got a question.

i have brougth the wild humper 6 wheeled chasis and a wild thumper motor controller.


everything is ooked up propperly, 

now my question is ow that i uploaded the standard program from my laptop on the controller(only changed to serial instead of rc as i want to drive it via my laptop). what code do i need to change to let the servos start driving?

myself i thougt this peace of code :




Right, back again with an update on my idea for a kick-ass fanctroller. So far, I've been coding away and right now, I'm up to the point where the actual fan control is implemented (I've already written the LCD-commands, several input functions, a setup and a menu.) But I'm having some problems.

My first PCB

Hi guys,

I started on some unfinished projects again but I could use some advice. I'm trying to build a board for the mini reef that can switch 6 devices (solenoid valves) at 12v DC with the PIC/Prop controller. I'm using diptrace for this as this seems to be the favorite choice. So far I love it.

I came up with the below but I'm running into some problems with the traces. Maybe someone can point out the right direction as I think that it must be possible to cross over a line (with some electonic component maybe)? The red circles are the problem areas.

Dagu Rover 5 & Arduino Uno /Help

Hello everyone.

I'm trying to make a robot for experimentation, something i can use in my studies aswell. I'm studying Electronics & Computer engeneering, first year, and i want a platform that i can improve in the years to come. 

I started playing around with LEDs and an arduino some time ago, this week i bought a Dagu Rover 5 with 4 motors and 4 encoders. The problem is i don't have the 4 channel DC motor controller. 

The mother of all fancontrollers... Hopefully

So, I'm the process of making the -in my opinion- ultimate PC fan/pump controller for use with a water cooling system.

The idea is to make a bracket which fits into a 5.25" bay and holds an LCD, some type of input (probably joystick) and an arduino, so the temperature responses are completely programmable. It should have three fan/pump channels and 3-6 (however many ADCs I have left, at least 3) temperature sensors.

How do you use a L293D Motor Controller with an Arduino MEGA?

I have recently received my order from ebay. A L293D Motor Controller for my first robot. I read the datasheet and other guides but i can't figure out how to use it, please help! I didnt order 2 so i only have 1, if it fries, i cant get another one or i have to make one. :(

My Persistent Brain - Rover 5

This blog entry is my persistent auxillary brain for robotics stuff.


Can't generally run a DC Motor from an Arduino because motors draw too much current and it would fry the board.  So the Arduino needs to provide logic controlling an external power supply.

different versions of dagu controller behave differently?


I posted this yesterday in someone else's thread and was advised to start a new one.  My message from yesterday:

Android phone as a controller

Hello there :)

I'm on the edge of purchasing an android phone. Looking at specifications around i thought: "Hey but this is the perfect controller for a robot!!" It has an incredible inventory of useful stuff: gps, compass for navigation, wifi, bluetooth and cellular for communication, huge screens for UI, speaker for talking, plenty of cpu, camera, easily programmable, and so on, all packed in a small package, all low power! And all for as less as $200! What do you want more ??

There's only a drawback: there's no simple way to phisically connect a device to peripherals :(

Drive system

Hi guys!

In my everlasting search for... well, basically anything interesting on the interweb, I've come across the RD02 drive system. This is a pretty powerfull motorcontroller, packaged with 2 encoded motors.

Some random features are:

An Arduino and a Playstation 1 Controller

I'm having trouble interfacing a playstation 1 controller with the arduino. the project will eventually be to use it  wirelessly to control a simple robot.

I was wondering if anyone has actually gotten the PSX Library on the arduino website to work and if so how, even if it turns an led on and off.
