Arduino & Processing – Getting values from SRF05 ultrasound sensor & serial port

I’ve started to delve into Processing and passing values between Processing and Arduino. If you’re wondering what Processing is, basically its an open source programming language for vizualising data that can interface with Arduino either by reading values/ pins or by setting them. Just remember that they are 2 very different things and require 2 different sketches! This is very cool if you want to display ...

Arduino – Sonic range finder with SRF05

A guide to using the SRF05 Distance Sensor with Arduino in order to calculate distances from objects. In this case I’m also altering the output of an LED with PWM according to how close an object is to the sensor. So the nearer you are the brighter the LED. So if we start with the SRF05, it’s an IC that works by sending an ultrasound pulse at around 40Khz. It then waits and listens for the pulse to echo bac ...
