Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino. Trump overpowers Musk's attacks on mega tax bill with blizzard of orders ...

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, ...

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 ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

His most recent exploit is to use the I2C-controllable chip to implement a Fast Simple QSO (FSQ) beacon with an Arduino. FSQ is a relatively new digital mode that uses a form of low rate FSK to ...

We like this approach because instead of doing some hard-core LCD ... Arduino, your add-ons are probably meant for a 5V power rail and logic levels. The RPi outputs 3.3V logic. You could use ...
