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.
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 and warnings
This is not meant for charging a battery from a USB Port from a computer. A USB
Port will only source 500mA max. If you want to use this to charge from a USB port
you would have to replace the resistor which is explained below. Even then, we
have not done tests to know if this will make using a USB computer port an option
with this board.
An ampere meter can only be connected to 5v input end of the module. When charging
it is better that the charging current is 37% of the battery capacity. So if you charge to the
battery of 1000mAH, current of 400 is enough. Make sure you use a proper gauge wire
for the current being used. Too thin and it will burn, too thick and the circuit may not act
correctly. Make sure the connection at the contract points are good. If the input voltage is
too high, like 5.2v, the current will be less than 1000mA, it is a normal protection function.
NO Reverse polarity, connecting the battery the wrong way will fry the chip.
The current can be altered (lowered) by changing the resistor connected to pin 2 of the IC
(at the bottom middle of the board in relation to the direction of the text). In the configuration
the module ships with the current is 1A. Changing out the surface mount resistor with a higher
resistance will lower the current. The chart below will give you estimates of some resistor to

Description: This is the same product as the Makey Makey Standard Kit. The difference is this version comes in fancy clamshell packaging meant for our distributors that need it. Regular customers are welcome to order, but we want to limit the amount of extra packaging finding its way into the trash heap.
Description: RFID (radio-frequency identification) is the wireless non-contact use of radio-frequency electromagnetic fields, for the purposes of identifying and tracking tags attached to objects. This is the ID-20LA, a very simple to use RFID reader module from ID Innovations. With a built in antenna, the only holdup is the 2mm pin spacing. Power the...
