Line Follower Robot with OpAmps

This is an old project that I found on my computer and decided to share with you guys. It’s that famous line following robot, made the simplest way possible, using only basic components such as LM358 OpAmp, LDR, Resistors and Transistors.

The LM358 comes with two Operational Amplifiers and I used it as comparator to make the robot stay on the right path.

ProtoStack Atmega32A Dev Board

During the past few days I have been playing with ProtoStack’s Atmega32A Dev Board and have been very happy with it. Along with the Atmega(8/16/328) dev kit, so far it’s one of my favorite boards.

It comes with everything you need in order to have it going , the big IC-ATMEGA32A-PU ┬ÁC, 10-pin connector (you can also use a 6-pin ICSP header), capacitors, resistors, voltage regulator for an external power supply and more… You can check the complete list and manual here.

If you are looking for an Atmega32A Dev Board, I would recommend this one for sure!

Relational Space #1

This work presents an urban intervention using interactive technology. Located within a pedestrian and small vehicles tunnel below a busy road, that connects two parts of the Federal University of Santa Catarina Campus, the intervention creates a new relationship between tunnel and road. It operates as a displacement, transposing the sound of the traffic above to the pedestrians below. A sound sensor captures the sound of cars on the road and transmits a signal to the Arduino board, bringing a sense of chaos into the tunnel from above. The installation was developed as part of the discipline of Interactive Technologies and Creative Processes of the Architecture and Urbanism department at UFSC.

This is the final project from an architecture class project that I helped with.
