To use the 5v output, as I have done to power the arduino, you need to use a jumper connecting the two pins just north of the power screw terminals labelled 5VEN. One of the handy features I was alluding to earlier is that the L298N has a voltage regulator that we can utilize as a 5v source. This will provide the power for the DC motors. The positive and negative from this go directly to the 12V and GND screw terminals on the L298N. Starting with the far right, you will find my usual barrel jack which I use to connect a 12v 4a power supply. Second, I am only using the L298N to drive one DC motor at the moment but you can independently drive a second motor with just one driver. I won't into the technical intricacies of the L298N, but it has some really useful features for not much money that is great for TipsyBrew.įirst off, if you haven't been keeping tabs on the project, I am using the arduino MEGA 2560 full time now because the OLED requires too much memory for the UNO to be reasonable. L9110 H-bridge module_fixed_92.fzpz (26.All we need here is an arduino, 12v power, 12v DC motor, and of course an L298N driver. 1 which would be explained by the px change) but displays correctly as aligned to.
92 exhibits the same offset that Fritzing sees when loaded in to. Unless someone can point out something I’m doing wrong I assume the change to 93 pixels per inch on Inkscape.92 is the cause of the change. The file above was redone after downgrading to Inkscape.91 again. Note that schematic is not only misaligned to the grid but scaled wrong in schematic (the pins aren’t on. That said, this is the same file that I edited last night using Inkscape.92. L9110 H-bridge module_fixed.fzpz (20.0 KB)
Comparing the files in this one to your original should tell you all that I changed (if not feel free to ask here ). The pins connecting in the center was because you didn’t have terminals defined (without a terminal the connection is the center of the pin). Then edited the fpz and cleaned it up (tried omitting the unwanted pins in pcb view but that doesn’t seem to help). Then (after I discovered Inkscape 9.2 appears to be a bad idea!) I adjusted the box in schematic to center the pins better and added the missing terminal definitions. I also changed all the connectors from the 0 width (that are invisible in Inkscape) to. The broad outline of the changes is that I ungrouped everything in both breadboard and schematic views (many many nested unused groups) then in schematic cleaned out anything that wasn’t an in use connector or a line on the drawing (there are a bunch of unused connectors in there that don’t hurt anything necessarily but are messy).
You have a variety of problems, missing terminal definitions mostly, as usual it was easier to fix them than try and explain how to fix it (although I also don’t know how to fix it so it is happy with the screw terminals).
