A brand spankin’ new big brother to the Duemilanove, the first pic of a new Arduino board has surfaced. The Mega uses an ATmega1280 surface mount chip and offers a whole big bunch of new features – 128KB of Flash 4KB RAM 4KB EEPROM 53 IO 4 HW UARTs 14 PWMs I2C bus 16 Analog […]
Xander Hudson, aka Synoptic Labs, posted this cool heart card project to the MAKE Flickr pool. He writes: This year I gave my sweetheart a LED valentines day card. The LEDs were animated with a pulse harmonic tuned to my own heartbeat. (sappy, yeah I know, but she makes me feel sappy). Incorporates 1 AVR […]
PJRC Electronic Projects has come out with the $19 Teensy AVR development board. It uses the AT90USB162, which eliminates the need for a separate USB-to-TTL chip: The Teensy is a complete USB-based microcontoller development system, featuring a 16 MHz AVR (AT90USB162) processor, in a very small footprint! All programming is done via the USB port. […]
Alex, of Tinkerlog, writes: The Problem: Whenever I was prototyping on a breadboard I was annoyed by all the wires to setup before the actual project could begin. Arduino projects were much easier. The 6 pin ISP (In System Programming) header alone was troublesome. Make an adaptor to plug a 3×2 pin header on a […]
Dhananjay Gadre has created another great project! We recently built a LED spinning top with message display. Its an improved version of a similar top published by Elektor in their December 2008 issue. The Elektor top can be spun only in one direction. The synchronization required to print message on the LEDs arranged along the […]
