Uses current generated on coils in stepper to act as an encoder
Pretty simple circuit I found, you may have to play with the resistor values to get the output to logic level depending on your steppper.It uses two voltage … Read more
setting fuses in a blank ATmega328P chip for use with Arduino IDE and burn the bootloader
Here is a little tutorial about setting the fuses on a blank ATmega328P in AVR Studio so you can use it with Arduino IDE: You need: Read more
There are various different chips which are commonly used with the Picaxe chip. Here I attempt to explain what each one does, where it goes and why you might care. … Read more
Creates many kinds of applications
Probably you have seen some interesting projects around here which use applications created on processing, such as: Read more
RTTTL, Arduino, Sound, Sounds, Music, Seeeduino
I was wondering why, despite the notice on the front page,  there weren't very many robots with sound. Then it hit me: people don't know how to make sounds with … Read more
Did you ever copy & paste your source-code from your IDE or editor into an LMR article    and found out that all syntax highlighting and formatting is … Read more
Ever wanted to know if your battery has just the right voltage to run your robot. Sometimes I stick a battery in a robot and it just limps over. I figures that the … Read more
Have you ever made a robot that ran fine when you held it, but when you put it on the floor it moved really slow (or not al all)? Hmm… Did you use a motor … Read more
Give a sense of touch to a robot using light
I've been trying to think of a good sensor to mount onto my polypod's legs (Yes, I'm still working on it) to give them a sense of touch.  Some people have very … Read more
sharing an experiment connecting a robot to Martin's 'shared brain' using a simple Python module
No matter how many hours we spend hacking code in our basements, our robots remain, shall we say, not the brightest lights in the harbor. Read more
A basic - intermediate walkthrough on programming in Spin
This is part 1 of a multi-part series.  The other parts are here. The Parallax Propeller can be programmed C, Spin, or Assembly; I think most people use Spin.  I … Read more
Converts the servo for use as a geared motor
It’s always good to have servos that works like a geared motor. That also can go in both direction and speed is adjustable, it’s very handy in robotic project … Read more
Shows how you can teach a single-axis move by using the Record/Play tactic
Using a
Did you hear about teaching a robot a move but don't know how to do that? Did you ever struggle around to make a polished mathematical way/time function more … Read more
Collect and crosspost my blog entries and discussions about programming topics.
Introduction I started blogging about various programming topics and the community has chimed in with some good information.  I plan on continuing to blog … Read more
communicates with devices over serial
I'm slowly building a library of programs in C# for controlling robots, writing tutorials for how to make them as I go. I will be listing all my programs for … Read more
