Arduino101 / tinyTILE BLE: Match-Making Sunglasses

Story Instead of using an app, what if you could send a signal to eye-contact someone you are interested in talking to, in a social setting, even from afar? I'm not proposing a different way to start a date. I'm exploring a new usage of Bluetooth in the field of human interactions. When I found out that Intel Curie modules can be assigned to act as central and peripheral BLE devices, I immediately wanted to ...

Using Nokia 3310 84×48 LCD with Arduino

Story The Nokia 5110 is a basic graphic LCD screen for lots of applications. It was originally intended to be used as a cell phone screen. This one is mounted on an easy to solder PCB. It uses the PCD8544 controller, which is the same used in the Nokia 3310 LCD. The PCD8544 is a low power CMOS LCD controller/driver, designed to drive a graphic display of 48 rows and 84 columns. All necessary functions for t ...

An Urban Plant Watering Solution

This device improves plant irrigation in urban environments. Powered by an Arduino 101, it uses on-board tools along with a few external sensors to calculate optimum conditions for watering plants in its own environment, and then waters the plant itself at the calculated time. It is based on the following concepts: Gravity and Pressure This device taps its water source from a reservoir, which I made using a ...

Cycflix: Exercise Powered Entertainment

Now that the cheesy title has pulled you (Fitflix was taken and I didn't want to be sued) I'll tell you about the project, it uses a stationary exercise bike connected to an Arduino Nano to control the streaming of Netflix on a PC, I started this project hoping I could get it working on just a Raspberry Pi but ran into a few problems I couldn't overcome which I'll discuss at the end. But the main gist of th ...

Controlling Robot Over Bluetooth Using Xbox Steering Wheel

So I'm guessing that I'm like a large amount of people on this site that are low key hoarders, keeping anything they could turn into a project or salvage for parts and this is an example of that. I have this old Mad Catz Steering wheel for the Xbox 360 and now that I have an Xbox one I don't really have any use for it anymore so decided to use it to control a toy car through Bluetooth. I would've liked to c ...

Can I Use an Arduino Uno for This?

So back when I first started working with micro controllers, Arduinos mainly the most annoying this ever was when i would follow someones tutorial for a project and they would use the Arduino uno, I would be using the Arduino micro or something, i would spend like an hour wiring it up following the instructions piece by piece, get all excited to turn it on and as i do it just straight up doesn't work - the ...

Distance Measurement Vehicle via Websocket

Story When you measure distance between two point general way is to use a ruler. But you can use a lot of other ways: by laser, map, foot or walking meter. The walking meter is very useful when you are measuring curved (not straight) distance. But it might be very tired because you should walk the entire distance. Here is a movie which is measuring distance. You can see that the vehicle is being controlled ...

Reducing Arduino Power Consumption

Story When it comes to portable electronics, one of the most important features is how to maximize the battery life. The ATmega328P, used on popular boards like the SparkFun RedBoard, Arduino Uno, and Pro Mini are actually quite power hungry. The RedBoard and Arduino Uno, draw around 15mA minimum, which doesn’t sound like much but as you’ll see in this project, we can drastically bring that down with just a ...

Arduino on Internal Oscillator Crystal as Clock Source

Story I have been working out ways to make a minimal Arduino to fit in the smallest space possible, and limit the power consumption of the microcontroller. (You can go through this project for more info about reducing power consumption at: Reducing Arduino Power Consumption). You can assume this one is an extended version of that project. An Arduino consists of many components like linear regulator, USB to ...

RPi Serial Console Automation Using Arduino

Story A Continuation of One Button Restart of a Stalled Raspberry Pi In a recent article, I showed how an Arduino Pro Micro can be utilized to send characters to the serial console of the Raspberry Pi Zero W. The Pro Micro was chosen because it is small, inexpensive, and easily acquired plus the integrated USB port provides a convenient way to easily upgrade the programming. (Always disconnect the ProMicro ...
