Why on the left side of the PCB you have B+, GND, B+, GND when having B+,B+,GND, GND would provide a simpler PCB layout without isolating the GND by having a Y shape trace of B+. Same for right side.Also please turn U2 90deg so the shunt resistor signal are same length.

Here is a kit that has no soldering!https://solarbotics.com/product/k_jb/You just need a screw driver (that comes with the kit)I design that kit while doing an internship at Solarbotics.

thanks for sharing!!

have you tried to understand the problem?it spin in circleis it one motor spinning forward?is it one motor spining backward?is it one motor forward and other motor in reverse?does in spin on in place or in big circle?are both motor actually working before soldering?did you press the switch to see if motor respond to switch press?post a picturegood luck!

Merci! Ça me fait plaisir. lol :)

Nice work! I was wondering the same thing. I wish my power supply of my Wanhao i3 Plus had a simple I/O to turn it off like all computer ATX power supply.

if you follow this instructable and remove all electronics, you simply apply 5V directly to the motor and it will spin continuously.

hey!I tried your code did not work. I made an issue on github.Regarding the code not compiling (trying to call length()) is what I posted in the forum. I will keep checking github.

dude so sweet!!! I had this running within minutes!! Darn easy!Using IFTTT, I send emails, notification and send data to google spreadsheet!I am in the process to add this to machine in my workshop so I can send usage data to spreadsheet and I will do some graphs and understand when I need to do maintenance!thanks a lot!!

You could look into pushsafer.https://www.pushsafer.com/It's a service that let you customize notification, you can tell how many motor virbration you want, what sound to play, what icon, etc. It has lot of potential. It's free for a X amount of push per month.it's basically PHP request, I tried and tried to make it work for the ESP8266 but no luck. It had to do with HTTPS no possible on arduino but Kevin (the guy behind pushsafer) change his side to do both HTTP and HTTPS.my thread is herehttp://www.appzer.de/forum/viewtopic.php?f=24&t=2729&sid=69465c80f2d333f8882a162d7b77483cI you make it work, I will check your instructable :P

hi, you can search youtube for tips on soldering. Don't apply to much heat (or leave your soldering tip too long on component). Don't "paint" or rub solder/soldering iron on parts. You're not Picasso. (I see too many kids do that!) If you're not comfortable doing something, try it on some scrap parts laying around. Be patient and have fun! and if you don't understand something, just ask for explanation or come here to ask me :P

nice work, that thing must go super fast with those big wheels!The third connection is a point in the circuit that let the motor current go in either the left batterie or the right batterie depending of the switch status. This makes the motor spin clock wise or counter clock wise depending of the path it takes.

hey man! I am happy you got this working!thanks for the info about that robot kit.I was not aware.I got use to people using/copying my work without credit. I have seen a lot of them!take care and keep making robots!!
