This is a small board with four tactile pushbutton pre-soldered and ready to connect to any project you have in mind.
This handy 1-channel relay interface board can be controlled directly by a wide range of microcontrollers such as Arduino, Raspberry Pi, AVR, PIC, ARM, PLC and etc. The relay input pin can take voltages upto 30VDC @ 10 amps or 125VAC at 15 amps.
Has an optocoupler for noise reduction and reduction of microcontroller reset from high inductive loads (I.E Motors) on the relay side.
Audio Piezo Transducer 30V, PCB MOUNT, 1.5V 75dB 22mm.
This device is driven by an externally driven signal (ex.: 2048Hz or 4096Hz) from a LSI and provide melodious sound.
Low power consumption.No noise and high reliability
The TS3A5018 device is a quad single-pole double-throw (SPDT) analog switch that is designed to operate from 1.8 V to 3.6 V. This device can handle digital and analog signals, and signals up to 4.6vdc can be transmitted in either direction.
Motorized Brass Ball Valves are effective tools for controlling water-flow by simply sending an voltage to either red or blue pin to toggle the valve to open or close at certain time intervals.
