Arduino Uno R3

Arduino UNO in Bangladesh The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller.

BreadBoard

Solderless Large BreadboardA breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). Because the solderless breadboard for electronics does not require soldering, it is reusable. This makes it easy to use for creating temporary...

Description

DESCRIPTION

Add another 16 pins to your microcontroller using a MCP23017 port expander. 
The MCP23017 uses two i2c pins (these can be shared with other i2c devices), 
and in exchange gives you 16 general purpose pins. You can set each of 16 
pins to be input, output, or input with a pullup. There's even the ability to get an 
interrupt via an external pin when any of the inputs change so you don't have to 
keep polling the chip.

Use this chip from 2.7-5.5V (good for any 3.3V or 5V setup), and you can
sink/source up to 20mA from any of the I/O pins so this will work for LEDs and 
such. Team it up with a high-power MOSFET if you need more juice. DIP package 
means it will plug into any breadboard or perfboard.

You can set the i2c address by tying the ADDR0-2 pins to power or ground, for up
to 8 unique addresses. That means 8 chips can share a single i2c bus - that's 
128 I/O pins!

SparkFun ToF Range Finder Sensor - VL6180

Description: This is the SparkFun “Time-of-Flight”  Range Finder, a sensor board for the VL6180  distance sensor. Unlike most distance sensors  that rely on reflected light intensity or reflected  angles to determine range, the VL6180 uses a  precise clock to measure the time it takes light  to bounce back from a surface.
