For the challenge, I wanted to send data from my computer's real serial port (RS232 9-pin connector). For that, I created an adaptor circuit because the voltages on a computer serial port are ...

Arduino Soil Moisture Sensor Circuit – Connection Diagram. Now that we have a complete understanding of how a Soil Moisture sensor works, we can connect all the required wires to the Arduino UNO board ...

Pin 2 on the Arduino schematic is really GPIO2 on the NINA, therefore it should not be labeled GPIO34. This is confirmed by the fact that the pin numbering on the Arduino schematic matches the pin ...

Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can ...
