Arduino and Motors -Robot Build Workshop Feedback

Thanks Glen, great session today. I can tell that everyone learned a lot and enjoyed it.

The workshop notes were also helpful - now I know a lot more about what we were doing.

Here are a few things that we noticed in the installation manual:

Step 4. You should have a 14” black and red wire, cut each into half, creating two 7” [red] wires and two 7” black wires, and strip all the ends.[Attach these to the lugs with the same color wire from step 3 for one motor from each assembly.]
Step 7. Attach the wheels and verify that both motors on the [side] spin in the same direction. Repeat for the second set of motors.!
Step 8. Attach the bottom plate to both motor plates. [If the holes on the side plate are too large for the screws, use an extra nut or wedge a short length of wire in the hold for the screw to bind to.]
Step 9. Attach the Battery pack inside the bottom plate with AA batteries parallel to the motor plates. [Use double sided tape.]
Step 11.Attach the Motor Drive board to the bottom plate using the 40mm x 1/2” Screws and washers screws, nuts, and tube extensions.! [Use double sided tape to prevent contact with the bottom plate if your kit doesn't include tube extensions]
Step 13.Driver Motor Board: use a small phillips to loosen up all the wire screw connections[. R]emove the two jumpers between the ENA/5V and ENB/5V - you can replace them edgewise on the two middle pins between the ENA and ENB pins.]
Step 15. Wire up the 6AA battery pack to the motor driver. The black wire to the GND and the Red wire to the VCC of the motor driver [wire screw connections]. Press the blue button and the motor driver led should turn on and off. Verify that led stays on Solid with all the wires firmly connected to the driver. !
Step 16. [change the wire colors to match step 24]
Step 18. [ I think this should come before step 15]
Step 17. [Attach a red M/F jumper wire to the 5V wire screw connector. Attach a black M/F jumper wire to the GND wire screw connector - twist the black wire from the battery pack around the male jumper pin if necessary to to get both wires to hold under the screw]
Step 25.Mount the Servo. [the holes in the servo mount may need to be drilled out to allow the screws to attach securely to the servo arm.]
Step 28. Wire the HC-SR04 to the Sensor Shield. [28.1.5V, Red 28.2.Echo (11) Green 28.3 Trigger S(12) Yellow 28.4 GND, Black!]

Hope this helps!
