Both Arms

A brief moment in history when both arms i have built from lolly pop sticks and spit

ACTUALLY WORKED AT THE SAME TIME

this minor miracle of alignment of stars was worthy of a blog entry.

LCD display for Arduino how hard can it be ?

Yeah so i thought i would have a play with an LCD display.

How hard can it be I foolishly thought.

in my ignorance I assumed they were all pretty much the same and spoke the same language.

My problem came when I wanted to talk with it on the UNO.

All the libraries are different.

Not being a good programer I tend to womble a bit of code from here and there,

and go off and do the fun stuff of building it,

and eventually get it to do what I want.

This becomes a bit of problem when the sketches are

made for different hardware.

second aduino arm

This is the

second arm i built

bigger base servo

better claw

more repeatable and less wobble

video of it working

picks up object

drops it at top of slide

repicks object

This is my first attempt at an arm

My first attempt at an arduino uno arm

4x micro servers

lollypop sticks

bent paperclips

and a whole load of hot glue

etc etc

powered by farnell 5v supply as very jittery on batteries

you tube video of it working (sort of)

first attempt at an arm

this is my first attempt at an arm

so keep the giggles to a minimum

when i power it from batteries 4xAA 6v its very jittery

but when i power it from a 5v mains supply its fine

what am i doing wrong ?
