Visualization: Pressure Sensor Matrix
This 28×28 matrix was used in the rSkin project to visualize pressure and location of pressure applied to a rectangular neoprene pressure sensor matrix that was wrapped around a robot arm.
Multiplexed Pillow
Super simple circuit using a 8-channel multiplexer, and may help you understand how a multiplexer works. Metal beads strung on conductive thread are connected to each of the three control pins so that they can swing and make contact with either GND(-) or VCC(+). 8 LEDs are connected to the 8 output pins of the […]
Multiplexed Matrix
The example in this post shows how multiplexers can be used to increase the number of I/O pins for sensor readings or outputs. A multiplexer chip uses control pins to toggle between multiple channels (3 control pins –> 8 channels, 4 control pins –> 16channels).
