We use PyFirmata firmware to give commands to Arduino using Raspberry Pi python script. PyFirmata is basically a prebuilt library package of python program which can be installed in Arduino to allow serial communication between a python script on any computer and an Arduino. This python package can give access to read and write any pin on the Arduino. So here we will run python program on Arduino using Raspberry pi.
So in this tutorial we will take advantage of this library and will use this in our Arduino board to control Arduino using Raspberry Pi.
In previous tutorials we have seen How we can build an Amazon Echo Speaker and then how can we control any Raspberry Pi GPIO using Alexa Voice. Now we are making an IoT project to control home appliances from anywhere in the world using AlexaPi and ESP-12E (or any ESP board).

In this tutorial we are going to learn how to interface the popular DHT11 sensor with Raspberry Pi and display the value of temperature and humidity on a 16×2 LCD screen
Today’s Tutorial relies heavily on the python library, Twython, which is a python module for interfacing with twitter. With twython, we could do most of the things you normally would want to do on your twitter handle like send DMs, Post tweets, read tweets, read DMs, Upload an image, change DP, Change background image, and a lot more. Twython requires authentication from twitter, which can be received by creating a twitter app.
Today we going to build a Remote Controlled Car using Raspberry Pi 3 and Bluetooth, here we will use Smart Phone as a remote to control the car.
Using this Raspberry Pi Fingerprint System, we can enroll new finger prints in the system and can delete the already fed fingerprints.
To make your printer accessible from multiple devices or computers, either you need a Wi-Fi printer or need a costly setup to build a Network Printer. So in this season of festivities, what would be a perfect gift than a Network Printer (did I just give someone an Idea?) but instead of spending hundreds of dollars for this new acquisition, what if you could do the same by adding a $35 Raspberry Pi 3 to that old printer laying around on your desk? Yes I thought it’d be awesome too!
