I'll offer the docs and all through my Blog. Try with Creatron, I have sent them the Gerber files, they should have the kits in stock soon.

I had forgotten to insulate the top of the USB connector on the Arduino Uno to prevent shorting against the bottom of the shield. Mea Culpa. I have them hooked up now and seem to have no shorting problem.Thanks Looks like I found it.

I will need to take a look at the Uno boards to see exactly what they did, but it might work if you just cut the pin from the shield that goes down in the wrong place. However, make sure the 5v shield pin gets powered from the Uno board or the shield will not work. Hi Basil,

I am sure they were purchased at Creatron. I mated them and just to understand some things, I tested the continuity between various pins. To my surprise, the +5v and GND were shorted. Good thing I didn't actually try to power this yet or I might have melted down big time. Looking more closely at the power pins of both boards, I find there are two GND pins between the Vin and 5v pins on the UNO, but only one GND pin between the Vin and 5v pins on the RBS. This means the 5v pin on the shield plugs into GND on the UNO. Surely this can't be right? It's a total short! What am I missing???

I have provided on the shield a 3 pin header area for sensor connections especially to make things easy. A bag of a 3 pin female housing and 3 crimp pins costs only a few cents, you can use long nose pliers to crimp them on the wires, then insert them in the housing in the correct order and you're done, no more risk of things not working because of a bad connection. Use the proto board for other type of sensors that can't be directly connected to the provided 3 pin headers. Now be careful, the 3 pin headers labeled "Servos" have battery voltage in the middle, not regulated 5V, you can use the pins for sensors, but connect the sensor power to any available 5V pin.

Thanks for your help while I'm also ordering the more efficient pololu motors you recommended :) I see, I plan on using a JST connector and connect the red to one of the 5v pins in the minibreadboard, black to gnd, and white to analog0…5.

I talked with the Creatron store owner and he's going to add the jumpers to the shields before selling them. About the second sensor, you should get a 3 pin housing and crimp pins from the Creatron store and crimp them on the sensor wires like this: black wire at the pin with the arrow on the housing case, then the red wire in the middle, then the white wire in the remaining hole. Then you can plug the sensor in a 3 pin header with the white wire towards the marking (A0, A1, ... A5) and the black wire towards the edge of the board. Since your first sensor is plugged into A0, plug the second sensor into A1. Oh, and you can do the same with the first sensor. You’re welcome.

The designer of the board met with me at the creatron store toronto and quickly solved the problem. Also, where do I attatch a second IR sensor so that it has 5V? Thank you very much for your help!
