So I am new to the audrino party. I am working on a group project. And here is the schematic:
There might be differences between the two pictures as we decided to add the wireless module to the audrino, and changed the pins for the motor.
The motor works perfectly with our audrino code for a day then suddenly breaks. Whenever it did not work, we thought it was our poor soldering and we did it again using new components (eg. diodes, transistor and resistor).
Until yesterday when we found out that when we replace the transistor it works.
We did replace it and minutes later it broke.
So I think the transistor keeps on breaking, which means we are using a rather weak one.
Components we are using:
12v DC 10RPM geared motor
I read many forums saying they used the TIP-120 yet I wanted to make sure am doing the right thing.
Is the 2n2222 transistor keeps breaking because it is weak?
Should we use the TIP 120?
