ARDUINO VS RASPBERRY PI: A MAKER’S GUIDE TO ENVIRONMENTAL SENSORS

Since joining the North Temperate Lakes (NTL) LTER site in 2014, I’ve witnessed a growing fascination among many individuals regarding the prospect of creating their own environmental sensors using Arduino or Raspberry Pi as the central computing unit. These devices are notably affordable, typically ranging from $20 to $30, and are much more user-friendly for […]

Arduino I2C communication with Raspi 2 WIOT

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

Raspberry Pi – homemade level converter for serial communication rs232 3.3 volts to 5 volts TTL for AVR microcontroller

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

Raspberry Pi Serial Communication: What, Why, and a Touch of How

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

Raspberry Pi and Arduino Serial Communication

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

Raspberry Pi & Arduino: a laser pointer communication and a LDR voltage sigmoid

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,

Raspberry Pi Android App communication

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

ClipBoard Communication PC Pi With Python

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
