- The circuit of LilyPad arduino is mounted on the DIP of ATmega168,328
- There are Reset-SW,Skech loading pin-header and LED of D13.
- Using internal clock 8MHz.
- Doesn’t put ICSP pin-header because there is no space.
- Writing the sketch uses an USB-Serial converter.
Demo Movie
LCD Digital Clock
It used “One Chip Arduino”, LCD and RTC. A breadboard can still afford.
Arduino on Arduino
Evolution
I made DIP a flat by force to hold down height. And added the pin-header of ICSP.
It’s form such as a weird bug. The downside is more weird. When it was connected by ICSP cable , and it hung down, it seems to be “that Bug” of The MATRIX movie.
One-chip Arduino ver. 2.0
- One-chip Arduino ver. 2.0 made a circuit on a small board and were equipped on a DIP.This idea to make a circuit on a small proto board was copied from thinduino of Mr.tokoya of “Junk Inn”.
- The characteristic of Ver. 2.0 is connected directly with USB, and to be able to uploade sketches from Arduino IDE.The external USB-Serial converter does not have need. It realize USB interface by the software.
-
This project is using modified schematic of the Metaboard. The Metaboard developed by METALAB. And it is using USBaspLoader firmware.
- Doesn’t put ICSP pin-header because there is no space.
