Messing around with Arduino can lead to some fun projects ... This is where those colored bands on a resistor's body come into play. Silver and gold are the two exceptions to this pattern ...

How the resistor color-code bands work At the heart of the project is an Arduino Nano clone and a potential divider that measures the resistance of the test resistor against a known fixed value.

That is capable of enabling your Arduino project to communicate with people and things using amateur radio bands. Coverage from the Arduino HamShield is across 136-170MHz, 200-260MHz, 400-520MHz ...

Robin Baumgarten has created a new experimental game which is controlled using a conductive rubber band which are available to purchase from the likes of Adafruit, which has been connected to a ...
