If there’s one thing that most events simply don’t have enough of, it’s robots. Robots, and saws. Not so Ada Lovelace Day Live!, which will feature the robot-wrangling saw-flexing talents of Sarah Angliss, composer and tech historian.
Light emitting diodes (LEDs) are being used increasingly as light sources in life sciences applications such as in vision research, fluorescence microscopy and in brain–computer interfacing. Here we present an inexpensive but effective visual stimulator based on light emitting diodes (LEDs) and open-source Arduino microcontroller prototyping platform. The main design goal of our system was to use off-the-shelf and open-source components as much as possible, and to reduce design complexity allowing use of the system to end-users without advanced electronics skills. The main core of the system is a USB-connected Arduino microcontroller platform designed initially with a specific emphasis on the ease-of-use creating interactive physical computing environments. The pulse-width modulation (PWM) signal of Arduino was used to drive LEDs allowing linear light intensity control. The visual stimulator was demonstrated in applications such as murine pupillometry, rodent models for cognitive research, and heterochromatic flicker photometry in human psychophysics. These examples illustrate some of the possible applications that can be easily implemented and that are advantageous for students, educational purposes and universities with limited resources. The LED stimulator system was developed as an open-source project. Software interface was developed using Python with simplified examples provided for Matlab and LabVIEW.

My school is kind of strange. We don’t have a cafeteria, but we do have a four week course on “The Simpsons.” We don’t have a jungle-gym on the elementary playground, but we do have a half-buried firetruck.
Some time ago I read an article about a contest called AFRON design challenge. The target of this contest is to get an affordable robot, with a cost of 10$, for learning robotics in schools.
So I thought it was a good cause to participate. I was thinking in a very simple autonomous robot (Traditional category in the contest), so I had the idea that a good point of departure to learn is a light follower: the robot sensors are seeking if there is a light source and when they find a light the robot goes toward it.
So if you have decided to tackle this tutorial I can assure you that this is the first and possibly greatest step towards becoming a Roboteur. One of the key components in all robots is control. In fact, that’s kind of the point of a robot. The best way to get control is with a micro-controller.
