Hi all tks for the valuable advise. is there a difference between the above dual motor controller and this dual motor contorller?http://tronixlabs.com/news/tutorial-l298n-dual-motor-controller-module-2a-and-arduino/
so far I have managed to source for the dfrobot code but not this tronixlab code. Are the codes the same?
Don't pay more than $4 for a L298N module. They're ubiquitous on ebay. The first one you linked to has the advantage of using an inverter on the direction pins is you can control direction with a single I/O pin. You can add your own inverter to the cheap L298N boards as save a lot of money.
Here's my L298N tutorial (I used a different microcontroller but the principles apply to the Arduino).
