    Flow sensor integration with the Car electronics system

    I need to integrate a Fuel flow sensor mentioned here to the car dashboard system, so as to display the flow readings on the dashboard screen and/or to a seperate display screen when fuel passes through the sensor . I'm specifically using this device which has a Working Voltage: DC 5V~18V...

    Car Relay Question - Momentary Button Activates Second Switch, Deactivates Itself Until Second Switch Activated??

    I’m never one to stop at “simple,” but often find myself overthinking things. MY QUEST: I have placed a simple keyed switch along the ground wire to the transmission shift interlock. I want to be able to leave my car on while I run out for brief moments and not worry about someone seeing...

    US blinkers circuit

    Hi all, I would like to make a circuit that turns on my two front blinkers on my car permanently, and when the blinker is activated, the lamp should blink as normally. I have no experience in circuit designing, but i was thinking that maybe it's possible to use a transistor, mosfet or maybe a...

    Car fan auxiliary heater

    Hi! Got a problem with my auxiliary heater. I connected an auxiliary heater to my car and everything was working great. However, when I added the wiring harness for the car fan, it won’t work. I can only measure 5v at the relay, which is odd since it should be 12v. In addition to this, the car...

    How would I go about creating a servo arm, controlled by arduino ?

    hiya! i am thinking of using an arduino nano and bluetooth to control a small car/robot. there will be a type of rake/filter on an arm at the end to sort litter. I want to be able to lift this arm (using servos?) and "shake" it to move the litter into a different compartment. How should I go...

    5v dc to 12v dc pwm design (automotive application)

    Hi guys I hope you can help I am by no means an electrical designer but I have a problem and are looking for a solution. I am trying to convert a variable 5v pulse into a rotation of around a max 2000rpm (12v motor) I’ve done some researching and a pulse width modulator maybe the way to go...

    Whats around for car ignition controllers spark ignited

    From just looking at my 4 cylinder 2 coil engine it maybe possible to have some logic that divides by 2 and switches output devices via a switch on dash to fire correct spark plug. Thus by adding a Carby we have something useful if computer dies or in the outback.

    Car radio with external bluetooth module only mono

    Hi! I have a 6006E CD RDS EON car radio and I build Bluetooth function into it. There are two 0R resistors in the wires from the radio module to the mixer module (it mixes the signal from the radio receiver and CD player and does a lot of stuff, which I don't know about). I removed these...

    so i have this car amplifier, that has a 4 channel audio port. (i think).

    So this port is broken and i cant find another one like it anywhere. maybe im looking for the wrong component since im not that good with components yet. Its a mchammer 1200w markII amp if that helps anything. is there any way i could fix it with just buying a single new port. i think it is...
