RA2L2 low-power MCUs are the industry’s first MCU to support USB-C Revision 2.4 with 15W CC detection, USB FS, CAN, I3C, and low-power UART.

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 ...

We all love seeing data represented in pretty ways — whether it’s necessary or not. Take VU meters for example. They’re a super useful tool for audio editors to balance signals, but they ...

Verify contrast (it could be too low preventing you to see text), you can adjust contrast using the blue potentiometer on the I2C backpack. Check the I2C address ...

Use testing mode in order to show "hello world" on the screen at arduino startup : Verify contrast (it could be too low preventing you to see text), you can adjust contrast using the blue ...

In this tutorial we will see how to interface NodeMCU with 16x2 LCD without using I2C communication ... If you have used 16x2 LCD with the Arduino board then it will going be very easy. You have to ...

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, ...
