When the piezoelectric ceramic shock will generate an electrical signal,
the analog port of the Arduino controller may perceive weak vibration signals. Can also be done with jobs related to vibration interactions, such as electronic drums.

Ideal to build a car with an obstacle detector, light follower Characteristic: - Voltage: 3 to 6Vdc

- Supply voltage: 5V
- Output Current: 10A
- Relay activation current: 15mA ~ 20mA
- Insulation: Yes
- Trigger signal type jumper (low / high)
- LED indicator
- Dimensions: 30x 54mm
- Has a jumper that allows to choose type of trigger signal (low / high)
- This module can be controlled directly by the microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL)

A multiplexer of this type actually only acts as a switch 16 to a 1.
The 4 digital pins are used to set high or low, (binary Y0-Y15) to determine which input pin is connected to pin "Z".
The control input S0-S3 is set to low "logic level 0", the signal C0 is connected to the output Z. Multiplexer 16 Channels CD74HC4067 MUX/DEMUX features:
- Based on chip CD74HC4067
- Analog signal input: Y0-Y15, 16 channels
- Analog signal output: Z pin
- Digital input, channel control: S0-S3
- Module size: approx. 4 x 1.8cm
- Package includes:
* 1 x CD74HC4067 MUX connection module
* 2 x row of soldering pins

Ideal for building a car with obstacle detector, light follower.
Includes battery compartment for 4 AA batteries and ignition switch. (batteries not included). 4WD Robot Smart Car Chassis 4x Wheels DIY features:
