Vintage radio hacked into a docking station
Mr. Oyvind from Oslo sent us a cool hack of a 75-years-old radio into an iPhone dock using an Arduino.
the Arduino is used to read the state of the dual potentiometer that controls the volume and then translate this value into a certain number of LEDs being lit on the volume indicator.I am using a Duemilanove. The code for the project is very simple and can be found here:http://www.build-electronic-
- An overview of the inside of the dock (very messy, I know )
- Here you can see the 4 wires used to control the volume display connected to digital input 2, 3, 4 and 5 on the left side of the board. And you can see the potentiometer connected to 3.3V, analog input 0 and ground on the right side of the board.
