Arduino Timer and Triggers - Automated Shutters - Instructables
The smarts behind this solution is an Arduino device that acts like an alarm clock but instead of sounding an alarm, closes the shutters :) The code behind the solution is generic and can be used as a trigger to any other operations / events you might want to perform.

Using a ground trigger with Arduino | All About Circuits
Feb 21, 2024 · Hey, i have a super simple Arduino project in mind that involves using the car door triggers (when the door is opened) to initiate a task. the car uses a ground signal as a trigger to let the ECU know that the door is opened. when closed there is no current present in the wires.
Trigger system - Programming - Arduino Forum
Mar 18, 2016 · The common way to communicate with the arduino from PC is to use a virtual Serial port. See the SerialPort class. If you need, there are many examples on this forum. Hello everyone, I have a question about how to trigger arduino. I have arduino mega on my Project. I am controlling 50 led with this arduino. It Works only when i give 9V.
Using a PushButton as a trigger in Arduino - Stack Overflow
Jul 7, 2015 · I'm trying to work with a simple Arduino circuit that increments a counter variable on pressing a push button in the circuit (connected as INPUT to PIN 8). My code is as simple as follows: btnPIN = 8; pinMode(btnPIN, INPUT); . lcd.begin(16,2); lcd.clear(); btnVal = digitalRead(btnPIN); if (btnVal == LOW) c++; lcd.clear(); lcd.print(c);
Trigger a loop - Programming - Arduino Forum
May 28, 2014 · Yes, once your loop function starts, the Arduino can't respond to anything because you've programmed an uninterruptable sequence using delay. Read my answer and watch my video to understand the correct way of doing it, then you will be able to respond to buttons during the sequence.
How Do I Implement Trigger and Echo Pin? - Arduino Forum
Mar 27, 2013 · How Do I Implement Trigger and Echo Pin? Arduino Mega 2560. Serial.begin(9600); printString("Start\n"); int i; for(i = 0; i < 2; i++){ pinMode(motor_left[i], OUTPUT); pinMode(motor_right[i], OUTPUT); // Servo. servo.attach(2); servo.setMinimumPulse(500); servo.setMaximumPulse(2500); turn_servo(100);
Arduino DS3231 Real Time Clock (RTC): Time and Alarms
This code shows two different ways to set the time: synchronizing the RTC with the system time (date and time the sketch was compiled), and setting a specific date and time manually by writing it yourself on the code. ... The following example shows how to set up two alarms and how to use them to trigger an interrupt on the Arduino. When an ...
Digitalduino: Trigger Buttons with Arduino
I need some way to control the RC car and i figured it would be easier to just trigger the buttons on the remote(as they aren't true analog joytsticks, just joy sticks with springy buttons). Here i will explain the two types of button you will most likely find in a circuit.
