Radar Screen to Visualise Sensor Data

Arduino + Processing – Make a Radar Screen to Visualise Sensor Data from SRF-05 – Part 1

Leave a Comment / Using Arduino / By

First things first, we need to build our circuit. This is the easy bit! We’ll be using the Arduino to control a servo that will rotate our sensor around 180 degrees. The Arduino will then send the value from the distance sensor along with the current angle of the servo to the serial port. Before proceeding please take a moment to check out some of my other work …

Arduino Processing 3D Sensor Data Visualisation

Arduino + Processing – 3D Sensor Data Visualisation

Leave a Comment / Using Arduino / By

So following on from my previous posts about visualising sensor data in Processing, I’m now looking at drawing 3D representations of the data recorded from the Sharp IR sensor – although can be any kind of range finder. I started by rigging 2 servos, one to pan left to right, the other up to down. The latter is limited to only …

Servo Feedback

Servo Feedback Hack (free) Using Arduino

Leave a Comment / Using Arduino / By

This Instructable brought to you by the kind folks a Rachel’s Electronics Visit  www.rachelselectronics.com  for cool electronics kits and breadouts! This hobby servo hack will add shaft position feedback by tapping into the servo’s own internal potentiometer. The only parts that need are wire and a little bit of solder, making this hack practically free. …

Servo Control by Weight (2)

Servo Position Control with Weight (Force Sensor) Using Arduino

Leave a Comment / Using Arduino / By

In this tutorial we will develop a circuit using Force sensor, Arduino Uno and a servo motor. It will be a servo control system where the servo shaft position is determined by the weight present on the force sensor. Before going any further let’s talk about about the servo and other components. Servo Motors are used where …

Automatic Railway Gate Control

Automatic Railway Gate Control Using Arduino & IR Sensor

Leave a Comment / Using Arduino / By

About a million people have died over the past 5 years in unmanned railway crossings all over the world. At least 1/3rd of the railway crossings are unmanned due to their remote placement and less traffic. The Automatic Railway Gate Control System using IR Sensor & Arduino focuses on systematic traffic control of railway gates that are both …
