HOW TO – Filtering noise with Arduino coding for Maxsonar sensor + robots – Customer Support Forums
This is a great forum post on Maxbotix sensors, and how to get good data from them for robots. We carry these sensors, you can get them in our store!

HOW TO – Multiplex analog readings – what can go wrong with (high impedance) sensors and how to fix it!
A user in the customer forums had a problem with multiplexing analog signals, they seemed to be very noisy and inconsistent. Turns out it was because the sensors are high impedance. This means that if there is capacitance on the ADC line or on any sort of sample&hold capacitor, it may take a while for read more...

Arduino controlled Silly String shooter
Eric writes in about his Arduino controlled Silly String shooter… here’s a quick rundown of what it does:   Sequence of events: -Detect motion (IR sensor) -Trigger Silly String (servo) -Play sound (funny laugh on a $4 Wal-mart toy recorder) -Transmit RF signal to second Arduino -Second Arduino receives RF signal -Wifi shield sends tweet (follow on Twitter: hackolantern) -Wait 20 seconds before it can read more...

Arduino Mario – Waveshield + sensors, great Halloween costume in the making!

Twittering humador
Longashes (a cigar social network) made a twittering humador… They write - I know what you’re thinking.. “not another device that tweets something!” Yup, another device that tweets something. This time it’s a humidor and it tweets that status of it’s relative humidity and temperature levels. For cigar aficionados, this means a lot. In order to read more...
