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
  • We have taken our popular 4-way Logic Level Converter and shrunk it to make this 2-way bi-directional Logic Level converter specifically for I2C communication between 5V and 3V systems. Ideal for connecting sensors operating at 3V to microcontroller systems running at 5V. There is even a 3.3V voltage regulator on board to power the 3V side.
  • Connection couldn't be easier. On the left, we have the connections to the 5V system (including 5V to supply power to the regulator), and on the right are the connections to the 3V side (including the 3.3V output from the regulator) 
  • Each mosfet has 10k pullup resistors on the 5V and 3.3V side so it works great with I2C.
