Arduino ultrasonic radar

Dejan Nedelkovski from How To Mechatronics has a very nice tutorial about making an ultrasonic radar using Arduino and Processing platforms. The project requires an HC-SR04 ranging sensor module mounted on a servo motor to scan the surrounding. The Arduino board control the scan position, as well as receives the ranging sensor output. The received echo data is post-processed on a computer using a Processing-based application and the radar signature is displayed on the computer screen. See this radar in action in the following video.

PC-based heart rate monitor using Arduino and Easy Pulse sensor

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

Low cost temperature data logger using PIC and Processing

This project describes an easy and inexpensive way of adding a digital thermometer and data logging feature to a PC. It involves a PIC microcontroller that gets the surrounding temperature information from the Microchip MCP9701 sensor, and sends it to a PC through an USB-UART interface. The USB port of the PC is also used to power the device. The open-source Processing  programming platform is used to develop a PC application that displays the temperature in a graphics window on the computer screen. The PC application also records the temperature samples plus date and time stamps on an ASCII file.

MikroElektronika’s “Ready for PIC” board talks to “Processing”

“Ready for PIC“ is one of MikroElektronika‘s compact prototyping boards for 28 and 40 pin PIC microcontrollers. The board comes with PIC16F887 microcontroller which is preprogrammed with an UART bootloader firmware and thus eliminates the need of an external programmer. The on-board USB-UART module allows the serial data transfer between the PIC and a PC using an USB cable. It has also got a reasonable size prototyping area to add more functionalities to the board as required. These features make this board an ideal candidate for doing embedded projects that require PC interfacing. This article first reviews the basic features
