adopted a h bridge here and facing issues

Hi all,

ages ago I found oddbots cool h-bridge on this page which works quite well. I started with 100x160mm boards and made two boards for two bridges in order to controll 2x2 motors.

A few weeks ago I got into contact with the pcb-tool Eagle and gave it a try to place two h bridges on one board 100x80mm (freeware edition).

As far as I can see I just copied the bridges. The only think that differs from the two-board version is, that I used the same power/gnd traces for both bridges.

time passes by quite quickly

Dealing with several circuits, which I found on this site and figuring out how to handle aluminium, I truely underestimated how complex building a functional robot is indeed.

My last post actually is decades old. I hope to present my robot in the near future and participate on LMR more frequently (I´ve been reading a lot here though). Working on a robot has shown me some kind of passion. The problem is to learn about circuits and living a life (work, private life etc.)

theory vs. soldering

Well...my robot is far from being able to be presented.

In fact I try to build/solder some parts on my own, which seems to be more challenging than expected. Actually I´m soldering a h bridge with its controller based on oddbots h bridge - without the current sensing part - and I just hat to face, that it doesnt work. I guess its not due to oddbots design, but to my soldering skills and or adapting to a simple board design, since I solder though-hole.

I hope I can figure out the problem soon...

question on a h-bridge circuit I found on this page

Hello everyone,

well, I´m pretty new to this community and I hope this post is not too dumb in your eyes. I´m more at home when it comes to computers but as soon as I get into contact with circuits and means to make a computer sense the "real world", I thought about giving it the opportunity to drive around next to other actions. In fact I´m trying my best to deal with microcontrollers and learn by doing.
