Make Controller

Overview

  • Set up your computer’s network settings to work with the Make
    • IP Address: 192.168.0.210
    • Subnet Mask: 255.255.255.0
    • Router: 192.168.0.1
  • Hook up the Make with an Ethernet cable directly to your computer
  • Hook up sensors or actuators to the Make
  • Power on the Make with either a USB cable or a power supply
  • Choose a widget to use (e.g. AnalogIn), and set these parameters
    • controller = make
    • controllerInputNum = port you have your sensor hooked to
    • controllerOutputNum = port you have your servo or other actuator hooked to
    • controllerIP = 192.168.0.200
    • controllerPort = 10000

Configure your network settings for the Make Controller over Ethernet

For Windows, please see the instructions on the Make website

For the Mac, follow the below instructions:

    • Open the Network System Preferences control panel
    • Create a new “Location” by selecting the pulldown menu labeled Location and selecting EDIT LOCATIONS
    • Click on the “+” icon and give the new setting the name Make Controller, and select DONE
    • Select the Ethernet icon on the left and set “Configure:” to Manually
    • Enter the three IP numbers shown in this screen capture
      • IP Address: 192.168.0.210
      • Subnet Mask: 255.255.255.0
      • Router: 192.168.0.1

Widget settings:

    • In AnalogInput (or any other widget used with the Make), the controllerIP setting to use for the Make’s IP address is 192.168.0.200. This works with the older, larger Make Controller. For the newer, smaller Make Controller, the controllerIP address should probably be set to 192.168.0.201. So if you find AnalogInput is not communicating with the Make Controller, try setting the controllerIP to 192.168.0.201.
    • In the widget, also set the controllerPort parameter to “10000”, which is the port the Make communicates on.

  • To make it work so that you can connect to the Make AND have Internet access over wireless, do the following
    • At the bottom of the left column, click on the gears icon and select “Set Service Order”
    • Then drag the AirPort word up to the top of the list of services

The best procedure for hooking up devices to the microcontroller is:

  • be sure the power and USB cables are disconnected
  • attach any sensors and effectors
  • plug in the Ethernet cable and USB cable to the computer and the microcontroller
  • launch the NET Connect Hub application
  • run your Flash application

Attaching inputs and outputs

  • attach the sensors and effectors before you power up the microcontroller. This reduces the chance that you accidentally short out the microcontroller by crossing wires while you hook things up.
    • ANALOG AND DIGITAL INPUTS
      • NOTE: Once you’ve used an input with the AnlogIn widget, the DigitalIn widget won’t work anymore. To fix this, just power off the Make Controller and power it up again. Then the DigitalIn will work.
      • each analog/digital input has three different kinds of screw terminals–ground, power, and signal. The signal inputs are numbered from left to right
      • be sure you attach the sensor ground (black), power (red), and signal (white) to the corresponding terminal positions. If you mismatch the connections, you may short out the microcontroller.
      • knobs, proximity, pressure and all other analog sensors typically have 3 wires as noted
      • switches and other digital sensors typically have only 2 wires, power and signal. Some microcontrollers (such as the Arduino) require three wires with a pull-up resistor. The Make Controller does not need this, and you can hook a switch up without any extra wiring or resistors.
      • by default, the 8th (number 7) input is wired to the trimpot on the board via a jumper. this makes it easy to test the controller without hooking up any external parts.
      • to hook up a knob (potentiometer) to the first input port, using Analog In Bank 1, hook the red power wire to the VIn1, hook the black ground wire to Gnd, and hook the white/yellow signal wire to port 0.


    • DIGITAL OUTPUTS
        • LEDs, relays, and other on/off effectors must be attached to the digital outputs. Usually, these have just two connections, a ground and signal. Do not attach to the power (Vout) connector.
        • To connect an LED to the first port, hook the ground wire to the Gnd connector in Bank 1, as shown below.
        • Hook the Signal or Power wire to Digital out port 0 in Bank 1

    • SERVO OUTPUTS
      • Servo motors should be attached to the servo outputs, with the ground brown or black wire at the towards the edge of the microcontroller, where GND is printed.
  • power up the computer, launch the NET Connect Hub, then launch Flash
  • plug the USB and Ethernet cables into the computer and Make Controller. For simple applications, the USB cable provides power to the controller. When you need more power, you can use a battery or wall plug power supply instead of the USB cable.
    • once the power is on, the red LED should go on and the small green LED should blink.
    • if the lights do not come on when you plug the power in, immediately unplug the power. This may indicate that there is a short somewhere, or that you’ve plugged the power in backwards. Check your connections, fix any problems, and try again. Of course, no lights may also mean that the USB cable is not connected, or the batteries are dead.
