Don't get us wrong, we love our Raspberry Pi. But if you're merely running a Linux image without adding a hardware hack into the mix you're missing out on part of the power for which the platform was developed.

Mebm: Arduino MEBM Messaging Library

MEBM stands for: Mouse's Ethernet Based Messaging, and is a super-simple protocol for sending messages between Arduinos over Ethernet based TCP/IP (i.e. Arduino devices with Ethernet shields on them, the integrated Arduino Ethernet board, Nanode and so on).

 

Each Arduino sends and receives MEBM Protocol messages using the Mebm object, which implements methods for constructing correctly formatted messages, sending them, and handling incoming messages.

Yesterday’s post was about plotting the response of a decoupling capacitor versus frequency. It might not seem like much, but this is in effect exactly what a Spectrum Analyser with “Tracking Generator” does! You put a signal with a known frequency and amplitude into a circuit, and you look at the amplitude of the signal that comes out
