Introduction

These instructions were for how to create the package from scratch. if you are using the idealab_ros repository you will not have to do all the steps

Instructions

1. add the arduino to the usb filter list in virtualbox on the host machine

2. plug in usb device and find out device info, including port

   ```bash dmesg

   dmesg | grep arduino

   ```

3. boot ubuntu, open terminal (ctrl+t) navigate to /dev, and list devices

   bash cd /dev ls -la

4. install arduino

   bash sudo apt update sudo apt install -y arduino

5. clone hx711 library

   bash git clone https://github.com/idealabasu/HX711.git

6. open arduino

7. install hx711 library
8. select port (/ttyACM0)
9. select programmer (AVRisp mkII)

10. make new directory in src/

    bash catkin_create_pkg force_plate std_msgs rospy roscpp

11. edit package as before

    1. add message
    2. catkin_make
    3. commit git

12. make scripts

    ```bash roscd force_plate/ mkdir scripts cd scripts

    pull talker

    wget https://raw.github.com/ros/ros_tutorials/kinetic-devel/rospy_tutorials/001_talker_listener/talker.py chmod +x talker.py

    wget https://raw.github.com/ros/ros_tutorials/kinetic-devel/rospy_tutorials/001_talker_listener/listener.py

    chmod +x listener.py

    ```

13. Modify as needed
