A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements.
The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. The motors rotation has several di..
The pump is basically a geared down DC motor, so it has a lot of torque. Inside the pump is a 'clover' pattern of rollers. As the motor turns, the clover presses on the tube to press the fluid though. The pump does not need to be primed and in fact can self-prime itself with water a half meter with ..
Solenoids are basically electromagnets: they are made of a big coil of copper wire with an armature (a slug of metal) in the middle. When the coil is energized, the slug is pulled into the center of the coil. This makes the solenoid able to pull from one end.
This solenoid in particular is ni..
This is a 14 pin IC Base with pins spaced at 0.1"(2.54 mm) . Use this IC base for easily plugging in and out ICs during prototyping. Also use this IC base to protect IC from damage due to heat while soldering by first soldering the base to the board and then plugging in the IC later. IC ba..
A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency.
This frequency is commonly used to keep track of time (as in quartz wristwatches), to provide a ..
This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. This chip is like a rotary switch - it internally routes the common pin (COM in the schematic, SIG on the board) to one of 16 channel pins (CHANxx). It works with both digital and analog signa..
16GB Micro SD Card (Class-10) for Raspberry Pi Model B+, Raspberry Pi 4Model B. Please note that the Memory card can be either of, Transcend/Sony/Kingston/SanDisk brand. This comes with the latest Raspbian Wheezy OS with an updated kernel/firmware. ..
Blue 16x2 Chars LCD Display widely used character displays. Extremely easy to use with all of the major microcontrollers.
You should have seen it on hobbyist as well as industrial projects As the name says it can display 16 characters on 1 line. There are 2 lines, which can be used to displa..
This is one of the most popular display device used. This is a 16x2 (16 Characters on 2 lines) LCD with Black font and Yellow Backlight.
There are many readily available libraries for interfacing it with Arduino, Raspberry Pi or other Development Boards and Micro-Controllers/Processors.Thi..
This is a 18 pin IC Base (DIP Socket) with pins spaced at 0.1"(2.54 mm) .Use this IC base for easily plugging in and out ICs during prototyping. Also use this IC base to protect IC from damage due to heat while soldering by first soldering the base to the board and then plugging in the IC later. IC ..
