Plug the RFID module into the breadboard with enough space around it. Connect the VCC pin to the Arduino's 3.3V (not 5V), and GND to the ground rail. For the data connections, wire SDA to Pin 10, SCK ...

To link a standard 16×2 LCD directly with the microcontroller, 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 ...

As you can see in the schematic all three TC74 sensors have their SDA and SCL pins connected in series to pin A4 and A5 on the Arduino board. The two 4.7K pull-up resistors must be used when using I2C ...

Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino. Trump overpowers Musk's ...

If you’ve got an Arduino, a few passive components ... could be modified for stereo as long as the two displays don’t have conflicting I2C addresses, he decided to simply duplicate the ...

[mircemk] is back to bring some of that design inspiration to a digital barometric display. The barometer is based around an Arduino Arduino Nano and a relatively large I2C display to display the ...
