In order to create this project, many physical materials are necessary, a lot of which will not be found lying around at home. In order to do this project, you should go out to computer stores or look online for these products. Keep in mind that you can upgrade to larger LED boards or faster arduinos, but that would require some modification of this tutorial as the coding, wiring, etc, changes with the addition of different products. Overall, this project is a fun way for you to practice your engineering, circuitry, and computer science skills while making a device that shows off your music taste in a new light.

Arduino Display for Liquid Flow Sensors

This project was done for a Friend Of a Friend. He needs to monitor water flow rate and quantity for his solar heating projects. He is mainly interested in this two inch sensor but also sent along a small plastic hose bib type similar to the Adafruit 828. Both of these sensors are turbine types, water flow spins a plastic wheel which magnetically triggers a pulse output proportional to the speed at which the wheel is turning. There’s lots of these sensors made for irrigation and industrial processes.

This Instructable will show you the steps needed to get started with the ESP8266 using a fantastic little development board for the ESP-12E module. The board includes everything needed including a USB to Serial adapter, surface-mount LED, and voltage regulator. In addition, it is easily mountable on a breadboard for developing your own IoT project(s)!

The main goal of the Instructable is to cover all the different options you can use in terms of firmware for developing applications that use the ESP8266 to connect to the web. The content, although available, is scattered throughout various sites around the web thus we decided to condense it in one place.

by codebender_cc @ instructables.com:

In this tutorial we will use an Arduino board as an ATtiny programmer.

To do this we will use one Arduino UNO board as an ISP (programmer) and one ATtiny85 micro-controller.

We will use Codebender – online Arduino IDE.

With the following procedure you will be able to program easily the ATtiny45 and ATtiny85 micro-controllers.

Hello, everyone !!! Today I’m going to show you how to make Arduino thermometer with DS18B20 digital temperature sensor, builded on breadboard and connected together with jumpers.

Info about the sensor – DS18B20 is 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it – allows for a huge number of sensors to be used on one data bus.

Open Inverter, an open source micro-solar inverter

open_inverter-600x543

Ken Boak has been working on an open source micro-solar inverter project:

We wanted to make a design that uses readily obtainable N-type FETS and an Arduino (more strictly a ATmega328P-PU on a breadboard) to generate the PWM signals and provide simple circuit protection, and load sensing. With the PWM signals generated in firmware it can easily be modified for 50Hz or 60Hz operation, either 115V or 230V operation and a wide range of battery input voltages.
We imagined that the final design could consist of an Arduino, an “Inverter Shield” containing FETs and driver ICs configued in a H-bridge and some voltage and current monitoring circuits. To make the inverter a 12V or 24V battery (or PV panel) and a 12V (or 24V) torroidal transformer would be added.

In this project I will show you how make two Arduinos talk to each other using RF frequency (wireless).

Now I will use the knowledge in all these project and improve on them by making one Arduino send data to another Arduino wirelessly using an RF433 module and displaying it on I2C serial LCD.
