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 ...
