Introduction

 With all the questions surrounding libraries in the Arduino IDE, I thought I'd start my next blog about creating a class used as a library for my Ping sensor.  As a start, I'll use the example sketch from the Arduino examples.  Below is the example code created by David Mellis and Tom Igoe with the majority of the comments removed:

I have seen quite a few folks on here replying to others with circuit diagrams. My question is what software does everyone use/prefer? I know some use Photoshop or Illustrator. Anything else anyone would reccomend?

ATTiny programming

By DaveyJones

DaveyJones's picture

I saw this link about programming ATTiny:

http://hlt.media.mit.edu/?p=1229

is it possible to make an ATTiny board to replace the Uno for programming other ATTiny chips?

they appear to have the same pins that are used by the Uno; 'SCK, MISO, MOSI'...

Library Basics - Optimization

By Maus

February 6, 2012
Maus's picture

The first Library Basics blog covered a basic conversion from a working sketch to a very simple library using the C++ class.  User mogul correctly pointed out some code optimizations that we can make.  His original message was:

You seem to waste a little resources here and there:

You store 4 private variables.

After about 8 months part-time development, after many VHDL-related headache, after lots of failures, after few successful moments, after anger, after surpises and finally with a big portion of luck I am today very proud to annouce the first working proof-of-concept for live stereoscopic vision using two CMOS camera modules, the Zeiss Cinemizer Plus video eyewear and of cause with my DIY side-by-side encoder.

Powering Arduino and servos/motors with one supply

By Vladimir

May 31, 2009
Vladimir's picture
Helo, all

I tried to power Arduino (Duemilianove) and servos/motors it controlled with the same battery, but Arduino continuously restarted during the operation. Actually it was a surprise for me, since Arduino already has voltage regulator chip and filtering capacitors in the input circuits...

I solve this problem by supplying them with different batteries, but I don't like this solution. Could anyone help - how to provide single power supply?

Request for electronic 101

By flokos

January 10, 2011
flokos's picture

Is it possible the more advanced people in lmr to make an electronic 101 tutorial or a series of tutorials

in order to make new members more familiar with electronics?

I mean for example ,what is a resistor what a capacitor why they are being used,then make some small projects

like a voltage regulator or a battery charger  and give examples of other simmilar circuits and have new members to make

their own pcbs  and know why they use each component ,like Chris(CtC) did with his son?
