An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small plate ("chip") of semiconductor material, normally silicon. This can be made much smaller than a discrete circuit made from independent electronic components. ICs can be made very compact, having up to several billion transistors and other electronic components in an area the size of a fingernail. The width of each conducting line in a circuit can be made smaller and smaller as the technology advances; in 2008 it dropped below 100 nanometers,[1] and now is tens of nanometers.

Thermocouple Amplifier Digital MAX6675

MAXIM IC MAX6675 Cold Junction Compensated K-Type Thermocouple to Digital Converter. This simple 8-pin SOIC IC attaches directly to any K-Type Thermocouple and interfaces via a SPI read-only interface.

I2C EEPROM - 256kbit

2 Wire Serial Communication (I2C) EEPROM - The back bone of any microprocessor project. These 8 pin chips need only two wires to communicate and retain their data even with power failure. Use the 256K EEPROM for some serious data storage!

Shift Register 8-Bit High-Power - TPIC6B595

Simple shift register IC that can control high-voltage/high-current devices directly! Clock in data and latch it to control devices like relays, motors, high-current optical devices, and more! Each channel can sink 150mA continuous, 500mA max.

$3.25

Analog to Digital Converter - MCP3002

The MCP3002 has a 10-bit analog to digital converter (ADC) with a simple to use SPI interface. Use this IC if your microcontroller does not have an ADC or have enough ADC lines. A great chip when you need to add additional ADC lines.

Hall Effect Sensor - US1881

The US1881 is an integrated Hall effect latched sensor. That’s nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor.

Op-Amp (Thru-Hole) - LM358

If you’re looking for a good, standard opamp the LM358 should fill most of your needs. It can handle a supply of 3-32VDC and source up to 20mA per channel. This opamp is great if you need to operate two individual opamps from a single power supply. Comes in an 8-pin DIP package.

Real Time Clock - DS3234

RTC stands for real time clock folks. The DS3234 is a low-cost, extremely accurate SPI bus RTC with an integrated temperature compensated crystal oscillator (TCXO) and crystal.

TLC 5940 - PWM Driver

The TLC5940 is a 16 channel PWM unit with 12 bit duty cycle control (0 - 4095), 6 bit current limit control (0 - 63), and a daisy chainable serial interface. It is handy for expanding the number of PWM outputs available.

Digital Potentiometer - 10K

Wire it up just like a potentiometer and use serial signals to ‘turn the knob.’ Another handy feature of digital potentiometers is that because they aren’t controlled mechanically, they don’t have a pre-determined sweep profile.In other words, depending on the way you write your code the potentiometer can ‘sweep’ in a linear fashion, a logarithmic fashion, or according to any other profile you like.

Dot/Bar Display Driver - LM3914 (Linear)

This is the LM3914 Dot/Bar display analog-controlled LED driver that uses an alinear output scale. With this driver all it takes is a single, analog signal to drive a string of 10+ LEDs, which can be configured into either bar mode (where all LEDs below a certain point turn on) or dot mode (with only a single LED on at a time). Hook them up properly, and you can create all sorts of nifty multi-LED displays.

Voltage Regulator - 12V

This is the basic L7812 voltage regulator, a three-terminal positive regulator with a 12V fixed output voltage. This fixed regulator provides a local regulation, internal current limiting, thermal shut-down control, and safe area protection for your project. Each one of these voltage regulators can output a max current of 1.5A.

Programmable IR Receiver - SIS-2

The SIS-2 monitors an IR receiver, and when a certain remote code is detected, an output pin will toggle. Two outputs are available and any code on any remote can be taught to the SIS-2. This makes it simple to implement an infrared (IR) remote controllable switching solution for a wide variety of applications. When used with an inexpensive IR receiver module, the SIS-2 recognizes IR signals from 2 independent IR remote control sources, and provides 2 modes of switching for your application.

MPU-6000 - Motion Processing Unit

The MPU-6000 is a serious little piece of motion processing tech! By combining a MEMS 3-axis gyroscope and a 3-axis accelerometer on the same silicon die together with an onboard Digital Motion Processor™ (DMP™) capable of processing complex 9-axis MotionFusion algorithms, the MPU-6000 does away with the cross-axis alignment problems that can creep up on discrete parts. The parts’ integrated 9-axis MotionFusion algorithms can even access external magnetometers or other sensors through an auxiliary master I2C or SPI bus, allowing the devices to gather a full set of sensor data without intervention from the system processor.
