ultrasonic-test

Purpose

Basic Arduino code to check the variance and test the ultrasionic sensors.

Getting started

• Download libraries for use teensy Arduino following all the steps in the web page
• Download the library for the ultrasonic sensors

Connections information

• Connect every pin with the correct pin in the ultrasonic sensor
• Datasheet ultrasonic sensor
• Pins information Teensy 3.2

download the Arduino program

Little Explication for each code

Measure_of_variance

Added file that measures variance

Simple__two_sensors

Simple code example from the Teensy and adapted for 2 sensors. It reads the cm of right and left and then is showed in the monitor.

Simple_two_sensors_LEDs

Simple code example with two sensors(right and left) and 3 LEDs(right, left and central).

Simple_three_sensors_LEDs

Simple code example adapted for 3 sensors and 3 LEDs. The cm are showed in the monitor.

Three_sensors_3LEDs

Code calculation and comparing with three sensors and 3 LEDs(right, left and central)

1D-ex-rosserial

Single sensor ros file

Three_sensor_ros

Publishes in Ros distance for all three ultrasonic sensors
