Using Arduino to do a communication between sensors and Windows for IOT.Personally, I believe that the use of Arduino is more practical when wanting to implement an interaction with sensors, since it is already available at a time, and has a much larger number of libraries. Story Personally, I believe that the use of Arduino …

Speaking Through Breathing: An intelligent communication system for the paralyzed. Things used in this project Hardware components Software apps and online services Python react-native Story Speathe: An innovative and evolving communication method for the paralyzed who are gone speechless after paralysis. Even if there are methods for the paralyzed Speathe lends a helping hand …
I found that the Raspberry Pi serial interface rs232, described in a older post by myself, was too bulky. Pi and AVR should be connected through a less amount of wires. So I’ve searched the best hints to solder a cheap and uncomplicated level converter, that can directly be connected between the GPIO of the …
I started exploring how to get a LCD display operational with a Raspberry Pi (RPi). I checked out two hardware configurations: the bare bone LCD 16×2 display driven by the HD44780 chip set, which takes 6 wires to operate, and another configuration that uses a Adafruit shield that requires only 2 wires. It quickly became clear to me that I knew …

Setup and Connections Connect the output of the Arduino TX pin to a voltage divider. The output of the voltage divider is then connected to the RPi GPIO pin # 10 (GPIO 15). The voltage divider drops Arduino TX voltage from 5V to 3.3V. In my case, I used 2 10K resistors connected in parallel …

Plugging the laser module on Arduino Isn’t easy to plug a module when you have no datasheet or some wiring schemes, the chances are that you’ll probably burn it if you provide a current greater than the supported. The module I have was bought on the DX.com and it came with 3 pins, “-” mark, …

Hello everyone Because app’s are being used almost everywhere, I decided to make my own tutorial on how to make an app and connect to a MySQL database hosted on a raspberry pi. For exchanging the data between the server and the client, I’m going to use JSON. Step 1: Parts For this instructables you’ll …
I normally use my Raspberry-Pi on a windows shared desktop. I also share a network drive with the Pi. This is great, but I still have the annoyance of the clipboard on the PC not being reflected on the Pi. There may be cross platform apps out there for this problem, but I though it …
