Arduino Send 12v Pulse

Good afternoon ! Im working on a project who uses some canbus data, data logging in a SD card, bluetooth and realtime clock. These components are working great together with the arduino Uno. But, the final task of the project involves to send pulses to two solenoids together, they draw around 11 amps in a very short period of time - around 20 pulses in one second and, after the pulses, will

I am creating a controller for a 12 V system using an Arduino Uno microcrontroller. For the outputs I am using a relay shield to switch the 12 V components. I have a 12 V toggle switch that turns on some 12 V components in the system and I want to use a trigger signal off of this same switch to send to an Arduino digital input.

Our use case Send x amount of 12v pulses to our test cluster to simulate speed and make the needle move. This signal is to simulate the differential speed sensor, which sends a 12v signal to the cluster. What's known Cluster expects a 12v pulse every 9 pulses equals 1 wheel revolution.

I have a 12V pulse square signal coming from an RPM sensor. I would like to translate it into 5V pulses since I will need to use it as input in an Arduino. More here Detect car 12V using Arduino. And a Littelfuse appnote about automotive noise. You could hack up a software solution to send ACO to a pin, and then you'd be able to have

For a 12v Solenoid If power button is turned on I want to send a short pulse to Solenoid i.e It activate it for milliseconds and then deactivate immediately and then when power is turned off it again sends a similar short pulse . I am basically an Arduino guy and do not know much about basic electronics I can make this circuit using arduino but

Hello, I'm trying to make a project that I can send i quick burstpulse of power to quickly turn a solenoid on then off, at button press to quickly create a pressurized burst of air for a project using Arduino Uno. I have no idea how to wire a circuit for it, or what code to make, I've tried several, I'm lost I'm trying to start simple first, trying it with an led. If you have an idea please

ArduinoPulseGenerator is a simple program for generating pulse sequences with pulse widths on the order of seconds to milliseconds using an Arduino. using an Arduino. There is an associated GUI that runs on the local computer, or you can simply connect to the Arduino with a serial console 9600 baud and send it commands. Pulse sequences

I'm trying to read my cars RPM using a digital input on the arduino. The signal I'm working with is a short 12v pulse at fairly low frequencies, what's the best way to get it down to arduino friendly levels? I'm having a hard time finding an optoisolator that would work, maybe I'm just misunderstanding things.

The voltage divider is OK, with ratio 4.76.84.7 0.41, so 12V will actually be read out as 4.9V. However, the switch should break the positive connection, not ground. Otherwise the Arduino input could in some cases be floating and give false readings. Sending the 12v directly in isn't a great idea. That would instantly destroy the Arduino.
