Hello everyone, sorry for the easy question but i can not find the answer. May I use a new motor shield r3 with an old arduino duemilanove? Can I just cut the pin that have no match on the duemilanove (like the two next to reset pin touching the two capacitors). Or the only way is to buy a new Arduino One with 1.0 pin layout? Thank you
The schematic shows the SCL and SDA (I2C/TWI) pins only going to the TWI-IN and TWI-OUT connectors. You can cut the pins off without hurting the motor control functionality. If you want to use the TWI-OUT and TWI-IN connectors you can and jumper the SDA pin to A4 and the SCL pin to A5.
