Once again Nathan Kennedy has created more features for his online Arduino-control system - teleduino. In this instalment he demonstrates how to control a servo - remotely - using http simple commands. The system really is very simple, and after a few minutes you can control the servos without any complex middle-ware or external services. Plus the servos can be set at a pre-defined angle, to avoid problems when the host Arduino board is reset.
Our Freetronics EtherTen is the perfect board for enabling your teleduino projects. Apart from being fully Arduino Uno-compatible, it has onboard Ethernet, microSD socket, full USB interface (so you don't need a costly FTDI cable just to upload a sketch!) and supports optional Power-over-Ethernet.
