for instance Arduino, you would need atleast 6 I/O pins to talk to the LCD. However, if you use an LCD module with I2C interface, you only need 2 lines to process the display information. Now a days, ...

By using a protocol called Inter-Integrated Circuit (I2C), the Wire library greatly reduces the number of wires required to connect devices. The protocol is supported on all Arduino boards ...

The I2C bus or TWI (Two Wire Interface) allows a single master IC to share communication lines with multiple slave ICs. In our case Arduino is the master and 3 x TC74 sensors are the slaves. As you ...
