Introduction Hi! In this update I will be taking a look at connecting a capactive fingerprint module to an Arduino MKR1000. I looked all over online, and could only find optical fingerprint sensors being connected to the Arduino, so I thought, why not give it a shot with a capacitive one, and if it works great! I want to integrate the fingerprint module to for now use it just a necessary switch, but will try using a solenoid in the device which would completely lock it. First, let's see what's a ...

With Dan returned from his vacation, we had a meeting to integrate all the code we had written so far, work on the circuitry, and begin the design for the case that will house the device when it is done. The code went together easily enough, though there were some bugs we had to work out. The first was that the Arduino audio library seems to interfere with the tone() function which will send a simple square wave to a piezo buzzer. We decided that if we were going to have full audio output anyway ...
#Blog5 Hello Everyone!   Happy Independence Day Its August 15, we celebrate Independence Day in our country.   Here is my work on integrating SD Card Shield and PAM8403 Audio Amplifier to Arduino MKR1000. Which is the part of  "Smart Voice Synthesizer, Visualizer". As per the design, the hand Gestures will be transformed into voice where this implementation play the key role.  Components Required Arduino MKR1000 Arduino UNO shield Arduino MKR1000 SD Card Shield PA ...
As said, I cannot afford hardware costing unless fully sponsored, here is the underlying model thought for this(some part & equations posted).   Those who have proper degree, very very simple for them, no explanation needed to them.   Those who dont have, it is complex, undeveloped and will undergo more revisions, just posted. But this will how obstacles will be detected by Arduino. IIR ,kalman filtering + Sliding mode observer and for other digital PID .  Rest ,I may post l ...
THE TRIKE SMART CODE In this blog and video, we'll see my approach to code and prototyping.  By starting with the code and commenting the code with the pin out purpose, I can quickly breadboard my circuits with the help of a highlighter - no schematic needed!     Here is the code for the Smart Trike:   /* Smart Trike by Sean and Connor Miller of Raising Awesome on YouTube GPIO Assignments: A0:  Motor Controller Killer (if it goes low, it kills the motor) A1:  Use ...
1. Selection of Whistle The most important part of the project is the whistle. Unlike BLE, WIFI or other remote control parts, the whistle do no need any power to keep it alive. You may think they are different, but to users, it is the same. Therefore, using passive sound wave-generator like whistle is one of the key features in this project. It would be reasonable to propose super-sonic  sound wave as controller to avoid disturbance. While, the performance of hardware limit the acceptabl ...
Welcome to our fifth blog post! This blog will be a little short, as we're essentially posting an update on the last blog.   We mentioned the Show and Tell model in that blog, and talked about its structure and capabilities of the model. We also mentioned that we will increase the number of iterations as well as finetune the model a little.   First, the outputs from the older model:   This model was trained for 1 million iterations. Now, we trained a new model, this time wit ...
Welcome back for my 6th blog in the "Design for a Cause - Design Challenge".

I came home from work, and there was a large box sitting on my chair. My first thought was "Wow, that is big." That thought must have actually come out, because my wife said, " yeah, I thought that it was bigger than you were expecting, too." Well, let's get down to unboxing the package.   These are the three boxes which were inside the mailing package. The one in the upper-right was pretty obvious, but I wasn't sure about the other two packages at all. The Maker IoT Bundle looks pret ...
