It has been 7 years (!) since I posted my PIC18F2550 KS0108 Graphical LCD Oscilloscope code and schematics. I have long since taken the circuit apart, sold my PIC microcontrollers, and moved on in my life (as one can surmise from my most recent posts detailing my graduate and postdoctoral work). However, I still get inquiries about the Microchip PIC oscilloscope, so I decided to recreate it using a simpler setup using my Arduino Fio.

Ihsan informs us of Digitstump’s inexpensive, powerful Arduino-compatible board with WiFi – the DigiX:
Have you seen this DigiX board by Digistump? They are the ones who created the Digisparks as well. As a difference from Digispark, this time they are aiming high end region of the devboards.

Do you think programming is difficult? Did you think Robotics is just for programmers?
We don´t think so. Our aim is to make robotics accessible to everyone.At Minirobots we have developed mOwayduino, an open source robot, based on Arduino technology. mOwayduino robot is ready to program, with multiple built-in sensors, motors and more.You don´t need to have any robotics background to start working with mOwayduino.

RK-1 is a wifi enabled mobile robot that you control using your iOS or Android tablet or phone that makes your Arduino projects mobile.
The RK-1 is a fun mobile robot, that uses an ad hoc wifi connection, which is controlled using your iOS or Android device.
The control board on the robot is built on the Arduino hardware/software architecture, which is open source, and the controller software and hardware will also be available open source. The idea is to give the community the ability to make Arduino projects mobile. There is no end to what you can do- you can add sensors and actuators to this fun little device and control it remotely.

The heart rate, also referred to as pulse rate, has been recognized as a vital sign since the beginning of medicine, and it is directly related to a person’s cadiovascular health. Today, we are going to make a PC-based heart rate monitor system using an Arduino board and Easy Pulse V1.1 sensor. Easy Pulse is a pulse detecting sensor that uses the principle of transmission photo-plethysmography (PPG) to sense the pulse signal from a finger tip. The sensor output is read by the Arduino board, which then transfers the data to the PC through a serial interface. A PC application is developed using Processing programming language to display the received PPG signal and instantaneous heart rate.

startingelectronics.com has a very clear tutotrial on how to read analog voltages using Arduino:
Analog channels A2 to A5 on an Arduino Uno are used to measure four different voltages. The measured voltages are displayed on a 16 character by 2 line LCD. The four channel Arduino multimeter can measure four independent DC voltages that can each be in the range of 0 to 50V. Voltages are displayed with one decimal place, e.g. 5.3V, 12.8V, etc.

The Yun board for Arduino aims to take DIYers into the cloud. The Yun is the first of a family of low cost, low power Arduino boards that run Linux and support Wi-Fi, following the trend toward the Internet of Things (IoT). Yun, named for the Chinese word for cloud, is designed to let the average tinkerer link a new Linux gadget to the Web using a simplified browser interface.
Yun links to the Web via the Hornet AR9331 Wi-Fi chip from Qualcomm Atheros, which supports 2.4 GHz networking and runs a custom distribution of Linux. The Yun roadmap features five products and two separate product families, including some boards designed to run up to four years on two AA batteries. [via]

Do you want to many processors on one board? Check this out. UDOO is an open hardware, low-cost computer equipped with an ARM i.MX6 Freescale processor for Android and Linux, alongside Arduino DUE’s ARM SAM3X, both CPU integrated on the same board! UDOO takes your DIY projects to the next level and it’s a powerful tool for education and creativity. UDOO could run either Android or Linux, with an Arduino-compatible board embedded.
We are delighted to announce a new mini-Pc board, UDOO, which integrates two processors, ARM i.MX6 by Freescale (for Android & Linux) and ARM SAM3X of Arduino DUE in a single board measuring 4.33 inch x 3.35 inch (11cm x 8.5cm).
On April 9th we launched a Kickstarter campaign which already reached the target of $27,000 in barely 2 days and keeps growing having raised 1700% over its target.
UDOO was conceived to both expedite the rapid prototyping of professional solutions and to support teaching activities in the field of physical computing, internet of things and interaction design. With the goal of promoting the use of the board in these domains we have built an international network of 5 universities: Carnegie Mellon University, USA; Aarhus University, DK; Siena, IT; OCADU Toronto CA; University of California San Diego, USA in order to share teaching experiences and to present solutions to create an open community accessible to everyone.
