Input Devices

In this task we will to some extent by a sensor that we added to an electronic board.
This task has been divided into three stages:

1) Manufacture of the electronic board.
2) Layout of the electronic components on the board.
3) Programming and sensor measurement.

 In general the steps are known from past work, the new sensor is measuring. I created three types of sensors: temperature, load and transceiver.
1) Manufacture of the electronic board: This part was easy with what we have learned in tasks 4 and 6 the MODEL was used to create the plate designs (PNG) take them published in the Academy and add a logo. Configuration parameters cutting software (Fab Modules), which were the same used in the previous tasks is displayed.

2) Layout of the electronic components on the board: This work was also easy given the skill acquired with practice in previous tasks. Shown below are the components of each electronic board created.

- Temperature



- Loading



- Transmit - Receiver

3) Programming and sensor measurement: For programming the FABISP, electronic sensor board FTDI USB cables and mini A. The steps used are:

  • Make connections to PC

               Temperature                                              Loading



             Trasmiter-Receive


  • Losing the Academy web programming code in "C" code to record the chosen sensor and code in python.
  • Open a terminal (Ubuntu) enter the folder where you saved the above files and execute the following command:
    • Sudo make-f (filename) program-usbtiny
    • Avrdude-p t45-c usbtiny-U flash: w (filename) hex.

  • Software with Python and measurement operation of the sensors is checked. Open a terminal and type these lines:
    • Python (Filename) / dev/ttyUSB1
