Add another eight pins to your microcontroller using a MCP23008 port expander. The MCP23008 uses two I2C pins which can be shared with other I2C devices, and in exchange gives you eight general purpose pins. You can set each of eight 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.

Add another eight pins to your microcontroller using a MCP23008 port expander. The MCP23008 uses two I2C pins which can be shared with other I2C devices, and in exchange gives you eight general purpose pins. You can set each of eight 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 eight unique addresses. That means eight chips can share a single I2C bus - that's 64 I/O pins!
The latest price of I/O Expander - MCP23008 in Bangladesh is BDT 490 You can buy the I/O Expander - MCP23008 at best price from our RoboticsBD or visit RoboticsBD Office.
