Hi can a Motor Drive Shield Expansion Board L293D For Arduino Duemilanove Mega2560 UNO can work at arduino uno R3?
Post a link or a photo of shield.
I have heard of:
- Arduino Duemilanove
- Arduino Mega2560
- Arduino Uno
But what is "Arduino Duemilanove Mega2560 UNO" ?
In any case, a shield for Arduino Duemilanove and Arduino Uno should work for an Arduino Uno R3. The only difference between Arduino Uno R3 and any older Arduino Uno is the component used for the USB interface. Shields are not affected.
Of course, you have to program the Arduino properly and connect the shield properly.
Uno shields may (will likely) have 2 pins that interfere with the electrolytic caps near the barrel jack on the Duemilanove, where the Uno was rearranged some for the 8-pin power header. One pin is not connected to anything, the other shorts out +5 to the caps and needs to be bent out of the way, or cut off. Uno shields will not be able to pick up SCL/SDA near the Aref connector by D13 because the Duemilanove does not have connectors there.
Okay, and I notice that the OP has not provided further details. However, this shield is apparently for Uno AND Duemilanove.
