Let’s select an arbitrary value of decimal 47. This code will use “counter” to simulate millis(). Every 255 counts it will roll over to zero. Every time we count up 47 steps, we will print the message “Trigger Event!”. //Pretend "counter" is "millis" unsigned char counter = ...
“currentTime” and “lastTime”. And finally, another variable is used to store the time duration. This variable is called “timeDifference” as it will be the difference between currentTime and lastTime. This is a “float” type of variable, which means it can keep track of decimals. ...
If you are making your own divider with different resistors you’ll need to change this. We define a float for the reference voltage, which in this case is 5-volts as we are using the Arduino’s power supply voltage as a reference. And the last variable we define is the value produced...
