COMA+ is PIC32-based instrument that can be used as calculator, oscilloscope, multimeter, analyzer and more. Ganzziani, project designer, said that one important goal project is to make the instrument low cost, so the capabilities of the PIC32 are being maximized. Since the device is going to be handheld, the power consumption needs to be minimized and the PIC32 has many features to accomplish this. A monochrome 128x128 display is used, which provides plenty of viewing area and only needs about 2mA to operate.Main Features of Coma+ including : 2 Channel, ...

The purpose of the project is to build a basic calculator based on microcontroller ATMEGA32. It uses 4x4 matrix keyboard as input device with a 74C922 decoder. This decoder generates an interrupt through External Interrupt INT0 every time a key is pressed. The result of calculation displayed on 16x2 LCD.MCU firmware is written in C language and is compiled using WinAVR. Basic math calculator project is designed by Jaime Andres Arteaga.

The project purpose is to build an AVR-based website total page hits counter and display it on 7-segments display instead of using only general scripts such as PHP, Java, CGI etc. The counter project consists of three main parts. First, PHP hit counter script run on website. This script will count the number of times a page is called and store this number into a simple text file (e.g. hits.txt).Second part is PC software which fetch text file web server every 10 seconds and send data to counter driver circuit. ...

The Arduino Drum Machine is MIDI groove-box features 14-track Drum-Machine Step Sequencer with 2 accent tracks and 32 steps. The project built based on Arduino and wusik software. It's like the classic Roland TR707 but with some twists, as it actually has 32 x 1/32 or 32 x 1/64 steps. This Drum-Machine Step Sequencer project designed to be plugs on top of an Arduino Uno, Duemilanove, Mega, or Mega2560 and compatible with Arduinos as well as Netduino and FEZ Panda.The hardware is a general-purpose MIDI development platform and playground, not ...
