10/30/2022 0 Comments Using arduino as timerWhen we lay this out on our timeline, we see that we have two events that overlap every five seconds. This is especially true when you have overlapping or concurrent events. When you’re creating a program that has repetitive timed events it doesn’t hurt to lay out the timing of the events on a piece of paper. Using arduino as timer serial#println(), to display those values to the Serial Monitor Window on our computer. Then we could use functions from the Serial library, Serial. Looking at this it appears we could use the Arduino millis () function to set up the timing for these events, and we could use analogRead () to read the LDR and the temperature sensor values. Think of the algorithm as our plan of action. Event 2: Read/Display Temp Value (every 5 sec).Event 1: Read/Display LDR Value (every 1 sec).Event 2 will read the temperature sensor and display it’s value every five seconds. We want Event 1 to read the LDR and then display that value every 1 second. We want the light-dependent resistor to read and display every second and the temperature sensor to read and display every five seconds. What we want to do is read these values and display them to the Serial Monitor window but we don’t want constant readings. We’ve got two sensors, a light-dependent resistor (or LDR) and a temperature sensor. This is more or less what we’re trying to accomplish. Drink Kool-Aid and watch a beautiful sunsetĮvery good program has an even better algorithm to go along with it, so before we start typing away at the Arduino IDE, first we want to write out our plan of action.Code from scratch a program using millis() to time 2 repetitive events.
