ZeroPhone: A Pi-powered DIY mobile phone

Zerophone: A Pi-powered DIY mobile phone

We have seen Arduino-powered cellphones before. Arsenijs introduces ZeroPhone– a Raspberry Pi Zero powered DIY mobile phone that costs less than $50 in parts. It is mostly open-source and linux-powered. It supports voice calls, texting, and basic apps like alarm clock, calendar, calculator, web browser, music player, etc. Features: Calling and SMS – this is the first functionality to be implemented, and will be considered crucial in the development. All the basic apps – alarm clock, calendar, calculator, phonebook, file browser, web browser and music player. Your own apps – SDK will be provided and it will be developer-friendly. The laand I’ll

Tutorial 2: EasyESP-1 “Hello World” Example

Connections for the “Hello World” example

After setting up the Arduino IDE to enable support for ESP8266, it’s time to write your first code for EasyESP-1 board. We will start with the classic hello world! example of electronics, a flashing LED. This is the best example to start with any new hardware platform as it gives us an opportunity to verify that the required software tools/drivers are installed properly and ready to rock. Hardware Setup In this example, we will connect the LD1 and D1 pins of J3 header together with a jumper wire as shown below. This will connect the LD1 LED near the bottom right corner of

Tutorial 1: Setting up the Arduino IDE for EasyESP-1

Adding ESP8266 support to Arduino IDE using Preferences window

One of the simplest way to program the ESP8266 chip on board EasyESP-1 is using the Arduino IDE. Following steps describe how to enable the ESP8266 support in the Arduino environment. Step 1 : Install Arduino IDE The first step toward setting up the Arduino platform for programming EasyESP-1 is to download and install the Arduino IDE. Go to the Arduino website and download Arduino IDE 1.6.11. Step 2: Install ESP8266 core package Next step is to install the ESP8266 core for Arduino IDE. It is an add-on that allows to write sketches for ESP8266 using the Arduino IDE  and its libraries. The easiest way

Managing a menu driven user interface on a Nokia 5110 LCD

User interface menu on Nokia 5110 LCD

An interactive menu driven LCD user interface (UI) is really useful in embedded applications that require setting up parameters for operation. This YouTube tutorial demonstrates how to manage a simple menu driven UI on a Nokia 5110 LCD for Arduino applications. This is the project we are going to build. In the display a simple menu appears, and with the help of three buttons I can navigate up, or down and select a menu item. Let’s select the first option. As you can see a new a UI screen is displayed and by pressing the up and down buttons we
