Arduino UNO R3 Micro Controller Board With DIP IC
|Country of Origin||Made in India|
Arduino Uno is a microcontroller board based on 8-bit ATmega328P microcontroller. Along with ATmega328P, it consists other components such as crystal oscillator, serial communication, voltage regulator, etc. to support the microcontroller. Arduino Uno has 14 digital input/output pins (out of which 6 can be used as PWM outputs), 6 analog input pins, a USB connection, A Power barrel jack, an ICSP header and a reset button.
How to use Arduino Board
The 14 digital input/output pins can be used as input or output pins by using pinMode(), digitalRead() and digitalWrite() functions in arduino programming. Each pin operate at 5V and can provide or receive a maximum of 40mA current, and has an internal pull-up resistor of 20-50 KOhms which are disconnected by default. Out of these 14 pins, some pins have specific functions as listed below:
Button Cell Holder
Minimum Order Quantity: 1000 Piece
|Brand||Different Brand Available|
A button battery holder adapted to be inserted into an electronic equipment is disclosed. As the holder is mounted into the electronic equipment in the direction parallel to the electrode surfaces of the button battery, a battery holder insert hole and a battery holder mounting portion to be formed in the electronic equipment can be made small, thereby contributing to a reduction in size of the electronic equipment. Furthermore, if the orientation of the electrode surfaces is incorrect upon insertion of the button battery into the holder, the side peripheral portion of the button battery is caught by the opposite side portions of the button battery insert opening at the time of little insertion, and further insertion of the button battery is inhibited because the sectional shape of the button battery does not become coincident with the shape of the button battery insert hole under the incorrectly oriented condition of the button battery. Thus, it is possible to prevent the button battery from being incorrectly inserted into the holder under the condition that the positive and negative electrode surfaces of the button battery are incorrectly oriented.
