What size stepper motor will I need to lift about 5 kilos
2  Using Arduino / Project Guidance / help with motor controlled router lift on: January 28, 2014, 04:56:28 am
Hi I am trying to build an arduino controlled router lift here is how it will work.
A dc motor will drive a threaded rod up and down I need to be able to control the speed of the motor preferably in percentages of full power ie 25% or 50% . But I also want to be able to control the distance the motor travels by 1/4 or 1/2 mm increments to a set hight . So I can set a hight and the motor will travel to it a the speed set or travel back to home at full speed..
I will also want a key pad or dial operated input system and a 2 line display showing hight and speed set .
To give you an idea
There is one on you tube here http://m.youtube.com/#/watch?v=hAL5eCIQOxw
The building of it is no problem and I realise I may need to gear down the shaft to get fine increments I want also I realise I will have to calibrate it to be working right.
Is this possible to do and if so how hard is it as I am a beginner at arduino
Thank you in advance

Hi I need some advice if my idea is possible first and secondly if there is some one willing to help me as I am nearly 60 suffering from conic depression and to make it even more fun   I am dyslexic so get confused over writing program's . It may be some one has already done this and you can point me in the right direction.
Here is what I am trying to do   
This control is for a remotely operated underwater vehicle
Top side Arduino UNO or Mega that reads the commands from a play station 2 game pad
It then send those instructions to 2 slave Arduino UNOs in the ROV by tether
And also revives data beck from the 2 slaves and displays them on an LCD
I have a full spec list if any one is interested in helping.

5  Using Arduino / Project Guidance / Component tester on: August 30, 2012, 05:29:06 am
Hi can any one help me please
I want to build an arduino based component identifier and tester like the ones you can buy from atlas
I want it to test resistors ,capacitors, diodes all types and transistors it should identify the component and it's pin outs as well as giving basic details of the component.
I know there are a few pic based ones out there but prefer to use an arduino if possable
If any one can point me in the right direction I would be great full

There no Internet involved just useing Ethernet is the most effective way of conecting the rov to the laptop over the 150ft teather

Hi the sensor shield and Ethernet shield are eBay generic ones.
I tried to ad pictures but it will not let me as the option is greyed out.
The ROV is a submarine that will dive to around 30m
It will be teathered to a lap top by a cat 5 cable

Hi I am building an ROV but have a problem I am hopeing you can help with.
I want to use a mega with sensor shield attached . I also need to conect an Ethernet shield
I was wondering if I could mount the Ethernet shield remotely on a Pcb enabling me use the sensor shield for my ESCs relays and servos ect.
If I can could any one tell me if I need to conect all the pins or just the ones the Ethernet shield uses
Thank you in advance

9  Using Arduino / Project Guidance / Re: I am Buliding an ROV need some shield advice please on: July 10, 2012, 08:48:36 am
yes i have based my design on theirs but they are using a beagle board now and i need to use arduino
i am finding arduino hard enough as i am nearly 60 never mind trying to learn another system

hi i have just started building an ROV (a kind of submarine that has a tether to transmit data)
i am new at Arduino and want to know if my idea will work before i purchase all the bits.
here is a list of what i plan to do
1. control 3 electronic speed controllers with brush less motors.
2. send information from a pressure sensor,2 temperature thermistors and an electronic compass trough the cat5 cable to my laptop
3. to allow steering from a joystick plugged into the laptop
4. to allow me to turn on and off 2 lights in the rov from the laptop
5. control at least 3 other outputs from the laptop for a robot arm

i am planing on using a mega or uno as i have both i want to control the arduino trough a cat5 earth-net cable so will use an earth-net shield. i also want to overlay the sensor information on to the video signal as there will be a camera in the rovso will use a video development shield and was thinking of using  a sensor shield to make connections easier.
my question is is this workable to use all these shields together and has it been done before and if so can any one help me sort it out.
thank you

might have it figured out after a lot of looking found this bit about 4 pin sockets on sensor shields
"This connector can go to external Bricks or other devices that have more complex Communications Protocols to work with Arduino. Examples are GPS receivers, Ethernet interfaces, and other complex devices. These are 4-pin connectors."

the manufacture is www.flamingoeda.com but all the info is in Chinese so i am still not sure but its the fact they have 4 pins that confuses me   the only thing i can think of is maybe digital servos but never used one so i don't know?

yes i can work out the the input and out puts that are just 3 pins but i want to know what the 5 4 pin black sockets are for

14  Using Arduino / Sensors / Re: new to arduino and confused with a sensor shield on: June 29, 2012, 12:53:37 pm
hi i had worked that bit out just wondering what the pin numbers are to read the inputs or operate the out puts so i can uses them in a program

hi i am hoping some one can help just got a arduino mega sensor shield but can find no information on it. It was brought for me as a present from eBay. i did not realize there were so many variations.
i have attached a photo of one the same i am hoping someone is using one the same and can show me what all the conections are.
thank you
