Madhu here for my blog post after a long vacation! For today's post, I am going to talk about a project that I had worked on as a fun learning project.   I came across this wonderful tutorial on Adafruit's website for controlling different types of motors using the V2 Motor shield. The detailed instructions make it easy to get started and I want to adapt these for the MATLAB Support Package (SP) for Arduino. With the support package, you can connect to your Arduino from a MATLAB session - ...
Madhu here for the weekly post..   I wanted to try out something cool and inexpensive. So I bought this Buzzer online. To make this work I hooked it up to the Arduino PWM signal pins, which runs at around 500 Hz (would be ideal to produce audible tone). I love creating electrical circuits using Fritzing and created this to show the circuit that I used. For the Simulink part - Once I found out that Arduino has functions tone and noTone, I set up a S-function builder block in Simulink th ...

"Make" this Halloween

Posted by Anuja Apte Oct 24, 2014
Hey! It's Madhu Govindarajan here - For this week’s blog post, I will share some ideas for makers who want to get creative with their Halloween celebrations. The few things that pop-up to mind when thinking about Halloween – Trick or treat, carving pumpkins and haunted house attractions. A custom Speech to Text converting script can be implemented with ease on Raspberry pi. This can be used to identify someone saying “Trick or treat” which can control an automatic Ca ...
I would like to introduce you to Madhu Govindarajan from MathWorks who will be writing interesting blog posts for next several weeks. Thanks Madhu! Hi everyone! Madhu here - I thought for today’s post I will share the answer to a frequently asked question during the recent Autonomous Fighting Robots Challenge (AFRC). Flexibility to build and expand existing solutions is one of key aspects fueling the Maker movement. I want to share how Simulink in essence supports the same thought proce ...
I had recently talked about how you can control servo motors using an Arduino and Simulink. I stumbled upon an interesting application which builds on the same topic. The video shows how you can use an IR sensor coupled with a stepper motor to get a rotational range scanner (I would have ideally called it a Mini Radar, but for the fact that the sensor uses infrared waves instead of radio waves). The stepper motor is controlled using an Arduino UNO and an Arduino MotorShield. The Arduino is conne ...
This blog post is a tutorial on how you can control servo motors using an Arduino Mega 2560 board and Simulink. If you are not familiar with programming an Arduino with Simulink, I would recommend that you check out the video linked below first. I had pointed to this video in an earlier blog post which went through the steps I had taken to learn Arduino programming with Simulink.   Now that the basics are out of the way. Let us get to the servo motor control part of this tutorial. Thi ...
I was browsing through YouTube today and found an interesting project video from Mohammad Alshawabkeh & Ahmad Alameer of the University of Jordan Department of Mechatronics Engineering.   They have created a robotic hand powered by an Arduino Mega and the Simulink Support Package for Arduino Hardware. The robotic contraption uses 5 servo motors and 5 flex sensors to identify the position of the fingers. Seems like a really great project. Check out the video below to see the robotic han ...
MathWorks organized a robotics competition as a part of the recently held Paris Maker Faire scheduled on June 21st and 22nd. The competition allowed participants to get their hands on a custom built mini Mars rover and play with Simulink and MATLAB to show off their robotics skills and received a raving response from a very large number of teams.                           ...
It's the Independence day weekend in the United States and a time for patriotism and fireworks . My colleague, Ye Cheng wanted to show her patriotism in her own "techie" way. Her idea: Light Paintings of the US flag. Light paintings use point sources of light to sketch shapes which are captured by a camera at a low shutter speed. Ye used 13 RGB LEDs for her paintings. The color of the LEDs are controlled by an Arduino Mega 2560, programmed using the Simulink Arduino Support Package and a Simul ...
This is the third post in the blog post series celebrating Arduino day 2014..   This post is about a low-cost mobile lab experiment kit put together by the talented folks at Minseg. This is an excellent example of the contribution Arduino has made to the field of engineering education. Experiment kits such as Minseg not only make control and mechatronics labs more engaging, but also make them accessible to a large student population.      The Minseg website has a number ...
This is the second blog post in a series of posts celebrating 10 years of Arduino! This series highlights how Arduino has powered a number of innovations in the field of education and engineering.   Robotic arms are used extensively  for numerous tasks from car assembly to picking up rocks on Mars. This video illustrates how you can build your own autonomous robotic arm using Arduino Mega with Simulink. You can learn how a robotic arm can be programmed to identify an object placed in ...
Happy Arduino day!!!   Do you remember racing a car in a video game, bumping into your opponent, your joystick happens to vibrate and you could feel the collision? This is the science of haptics. Haptic devices provide users a sense of physical interactions with real or simulated systems. The haptic paddle was originally developed and used as a teaching tool for dynamic systems at Stanford University.    You may be wondering how this is related to Arduino?   Arduino has b ...
