Code for an D1 Mini pro to measure water height via a JSN-SR04T and send the result to IFTTT that will send it to a Google spreadsheet. There are only a few tide sensors in Fort Lauderdale's new river ...

The measured height is displayed on an LCD screen, and the system can be turned on or off using a switch. The project is built using an Arduino Uno as the microcontroller Working Principle: When the ...

We start our arduino flex sensor code by defining the pins for the flex sensor and LED. Next, we define some variables where we have defined all the required parameters like VCC, the value of the ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...
