SHT75 Sensor
After reading the datasheet, your sensor is not using I2C protocol. No wonder you connect like that. How do you read the data? Do you manage to read the bits?

SHT75 Sensor
Why you use VCC = 4.05? How you get 4.05V? Not 3.3V or 5V? Also, as meslomp pointed out, no pull up in SDA? Your schematic shows no connection for pin 2 Vdd and 3 Gnd? Or maybe I...

Starting on CAN
Thanks Mike, you should be called the CAN expert! I found some info on the max distance for CAN. ISO 11898-2, High speed CAN, max distance is...

Starting on CAN
I was once told the CAN max distance (at slow speed) is 50 km without repeater (by a so-called embedded system expert)! Is it real/practical or just academics? What is the real...

mega 644V dead
What abt other ports? Have u try to blink your LED other ports too? another suggestion:- rather than using the _delay_ms, try to use your own delay loop and see it works or not....

AVR cross reference
In order not to hijack this thread, I already PM you the reason why initially I think it is 10x (Ok, I am a bit exaggerated too much, and give misleading info...)

AVR cross reference
If cost is not an issue, why not just pick Atmega644P? Atmega644P is the best you can get for DIP package (besides the Atmega1284P, which is overkill and sometimes hard to get) I...

An alternative to servo is stepper motor. Stepper motor is much easier to control, but it is open loop.
