Dear all.
I have solar tracking system . currently i am using below setup working Fine with Arduino UNO .Let me know if any way to reduce pin usage here LCD & Keypad Shield Quickstart Guide | Freetronics uses 6 pins
I have Motor Driver :uses 3 pin one PWM, 2 for controlling action
wind sensor: analog pin 1
INC sensor: Analog pin 1
DS1307 RTC : SDA & SCL
LCD :[A0 & A2](http://A0 & A2)
Buy a display with I2C interface. Or use a shift register (connected to SPI bus) to create 8 outputs for the display.
You have a SPI bus (for the Ethernet Shield) and a I2C bus. So make use of that.
I didn't know the ChipKit UNO32. I think it is hilarious. It emulates the software and hardware of an Arduino but not 100%. So it is much better to use real Arduino board with the latest updated libraries and so on. The Due has more processing power. Even a Teensy board is a good option : Teensy USB Development Board

can you share me the where i can get it . Which compatible with arduino Board. and i gone through link after your post. but seems it require more pin that nomal
Chipkituno32 i wrongly pasted , It has sufficient pins to do program and also equivalent clone of arduino with More No I/OS and cost wise it is twice of arduino UNO.
