My goal is to send data (in this case results from an ultrasonic range finder) over wifi to a computer that’s ready to display whatever data it receives.
This is what I’ve collected in my shopping cart so far (I also got some tools like a static mat and a bunch of those Third Hand things):
Arduino Starter Kit - Flex (Uno) - robotshop.com/ca/arduino-starter-kit-flex-uno.html
DFRobot WiFi Shield V2.1 for Arduino - robotshop.com/ca/dfrobot-wifi-shield-v2-1-arduino-2.html
DFRobot URM V3.2 Ultrasonic Sensor - robotshop.com/ca/dfrobot-urm-ultrasonic-sensor.html
XP-100 DC Voltage Power Supply / Battery Eliminator - robotshop.com/ca/elenco-xp-100-power-supply.html
Are there any recommendations or obvious oversights before I place my order? I’d like to be able to get all the supplies required at once, so I’m okay with a big order. I’m looking for every required/desired component other than the listening computer and wifi access point.
Thanks 
I swapped out the power supply for a wall adapter and added some tools to learn to solder with. I think I’m about ready to place my order, but I have something else in mind that I just realized I wanted. I’d like to have a turntable capable of being given an angle to rotate to. How would I go about building a controllable 0 - 360 degree rotating platform? I read about some servos being controlled with rotation angles and I saw this Vex turn table kit, but it seems rather incomplete.
Thanks again!
The power supply is a bit overkill - you really only need a 9V to 12V wall adapter (500mA+). The power supply is a good longer-term investment though. A few extra cables are always helpful, but it looks like you have what you need. Feel free to connect it to MyRobots.
Almost all servos can rotate from 0 to 180 degrees, though the 785HB can actually rotate 1260 (3.5 rotations) and also continuous rotation CW or CCW. A servo is very easy to control. You also have the option of a DC gear motor with encoder (unfortunately the positioning is not absolute), a stepper motor etc. though these are arguably a bit harder to control, and you need a motor controller. Take a look at the lesson: Making Sense of Actuators for more ideas.
