GND of the module is the common (0V) connection. The digital signal output to be detected (usually marked as DO in the module) is applied to D2 input of the Arduino. Analog output (marked as AO) from ...

I enjoy seeing modules that can make designing other devices easier, and when I did a call for design reviews, [enp6s0] has submitted one such board to us. It’s a module called TinySparrow (G… ...

[Kaushlesh Chandel] prototyped a few projects on his Arduino that use an HD44780 Character LCD. Wanting to keep these projects in one piece, but not sacrifice his Arduino board, so he etched his ow… ...

“The solder pad spacing along the length is the same as the Pico surface-mount footprint, however you have to allow for the Pico PCB width [21mm] plus 3.64mm.” Gold-plated conductive parts in the ...

Here, Arduino’s (Uno R3) A4 (SDA) and A5 (SCK/SCL) pins are used for the I2C control, and the module is 3.3 V powered by the Arduino itself. It seems that external pull-up resistors for I2C lines are ...

The PCB Direct virtual breadboard has been created to allow anyone to create interactive virtual breadboard circuits for platforms such as Arduino, ARM, PIC, Raspberry Pi and more, with the ...

This module will investigate creating an interactive side-scrolling game using an Arduino. It will also provide experience with advanced usage of the 16x2 LCD screen and its scrolling capabilities.
