Muxing Around With The CD74HC4067 + Arduino

Have you ever found yourself running out of pins to read an array of analog sensors? Don’t worry, you’re not alone, it happens to the best of us, and there is something you can do about it. An analog / digital multiplexer like the CD74HC4067 (mux for short) can help multiply the amount of pins you have, and it is insanely easy to connect to your arduino or other microcontroller The CD74HC4067 is a 16-Channe ...

Analog Sensors using arduino

Analog sensors produce an analog (continuous) voltage that typically varies from 0 to 5 volts. They have three wires – ground, power, and signal (typically red, black, and white, respectively). Examples shown below include: Potentiometers Proximity Accelerometers Ribbon Bend Pressure Light Temperature Sound Multi-touch Touch Other Potentiometers Potentiometers typically measure rotation or linear travel, an ...
