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.

This IOT project started out serious, then I kept thinking of funny things I wanted to make it do. The only way I could think to present it was a corny infomercial … Read more

The Dangers of LED Constant-Current Boost Drivers - Hazardous to your Arduino!

Does this picture look familiar to anyone?   In particular, the raised bump of melted plastic on what used to be the voltage regulator for the Mega2650?  I hope not too many! 

Trinity robot chassis upgrade!!!

Dear: LMR

Just to let you know I have recently built a new chassis for my trinity firefighting robot. The purpose of me building a new chassis was that the old chassis was too diffucult to use and debug. FIrst of all it was a self ballancer robot which made it diffucult to control. Second of all it was so tiny it was diffucult to debug the wiring. Any opinions on the new chassis? Thank you.

From: Noah

PS: I used the same electronics from the old robot to the new robot including motors. Enjoy!!!

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.
