Among the main advantages of these microcontrollers: they are cheap, robust and simple to program. Therefore ... The Alphanumeric LCD for Arduino will be our first circuit: using only one component, ...

I have the LCD already obviously but am pretty confused about what I'm supposed to use ... arduino boards' can range from the nano, which still retains a USB port (for serial/programming) to ...

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 ...

[Chris] wrote us to share a neat technique he has been using to program the Arduinos he uses in his projects. He likes to build bare bones Arduino clones rather than sacrifice full dev boards ...

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 ...

He also integrated a 3W amplifier into this build, and everything is controlled by an Arduino including a small LCD screen which displays the current tuned frequency. With the addition of a small ...
