Car arduino

Types of car arduino projects

There are several types of car-related projects that can be done using an Arduino, depending on the type of car and the desired level of complexity.

Telemetry system

The telemetry system will give real-time data about the things like speed, tire pressure, and engine temperature.

Parking sensors

Analog ultrasonic sensors can be installed on the rear of the car to detect any obstacles in the car's pathway. A small light or speaker can be installed to alert the driver when objects are too close.

GPS speedometer

This Arduino speedometer project only requires a GPS module. The GPS module is placed on the car to retrieve coordinates continuously. The coordinates will be sent to the Arduino, which will calculate the car's speed and show it on an LCD.

The coordinates on the car will retrieve the GPS Latitude/Longitude, and then the Arduino board will calculate the speed using these coordinates. This project shows how just an hour of free GPS data can be turned into something useful.

Bluetooth speed limiter

This Arduino car speed limiter project will restrict a vehicle's speed. Even if this project is simple, it can improve safety and fuel efficiency and lower maintenance costs. It can also be installed on any vehicle. For this project, an LCD and Bluetooth module are needed to monitor readings.

Live OBD2 Monitor

Many people want to know how to use an Arduino on OBD2 cars. OBD II stands for On-Board Diagnostic, a system made in 1996 to help mechanics retrieve trouble codes even without machine inspection. With this DIY OBD2 scanner, the car's state can be monitored in real-time. Showing on an LCD will turn out to be even more informative.

Wi-Fi gauge

If people's vehicles have OBD II, they can use this project to get readings without wires by connecting a Wi-Fi shield or module.

USB devices tester

This is a great project to test how fast a USB device can transfer data. It can also be a good learning experience.

Full control system for RC cars

This system is great since it can help even the most wild remote control car helps with DIY projects.

Automatic wipers

This project uses a rain sensor and an Arduino board to automatically turn the car's wipers on when it rains. It's great because it helps save on the car's wiper motor and human effort during heavy rain.

Commercial projects and uses of car arduino

Carbon footprint can be reduced by building many commercial applications for cars with Arduinos.

Automated fleet tracking system

GPS trackers for cars can be made using small gadgets, and such trackers are handy in logistics and transportation. Fleet tracking can be done in different ways, including tracking the position of the vehicles and even the performance of the drivers.

Telematic dongles

These small plugs can link a vehicle's OBD II port with a mobile application via an Internet connection. Telematic dongles can be used to measure the mileage and provide real-time information on the location and state of the vehicle. They are used in car insurance, logistics, and vehicle surveillance.

Device-to-car communicators

These systems link mobile devices to vehicles for remote control capabilities, such as unlocking doors or starting the engine.

V2X systems

Building vehicle-to-everything communication that will allow vehicles to transmit information on speed, traffic conditions, and safety to nearby vehicles and infrastructure to help avoid accidents and minimize traffic jams.

Licensing shootings

Kill switches and other devices that turn off main parts of cars used in money collection can be built using Arduinos. These devices can suddenly shut down a vehicle based on mobile communications.

DIY projects of car arduino

Even without any commercial applications for Arduino in cars, several DIY-based projects can still provide a social benefit.

Time speed monitor

Speed measurements taken with a smartphone will not be perfect because of the disturbance caused by our hands during measurement. This device can be placed on the dash during runs to give accurate speed readings.

Vulnerable road user detection

Ultrasonic sensors can be installed on the belly of big trucks to detect someone who is in danger of being unnoticed by the driver when driving close to the edge. This can be done by noticing pedestrians or cyclists within the area and sending an alert out.

Blind area view enhancement

Propagandist mirrors can be applied to reduce blind area problems in some vehicles. However, these propagandist objects are flawed because they distort image perception. An Arduino construct can give an accurate image of the area behind and beside vehicles, which is better than any convex mirror.

Road safety design system

Every year, many people die because they did not wear their seatbelts, and unsafe driving also claims a lot of lives. An Arduino project can be made, which will monitor seatbelt usage and driving style, sending alerts to people who are driving unsafely or are not wearing seatbelts. This can help the person driving a car and, at the same time, reduce road accidents.

Industrial/ Manufacturing considerations

In some cases, cars with electronic parts, like the car stereo kit, must go through stress testing and certification, especially for more sensitive Arduin-based projects.

• Operating temperature ranges of up to 100°C are usually found in vehicles. Therefore, all electronic components and connections must be rated to sustain such temperatures. Normally, stress tests are made to check if they still work under high heat.
• The automotive environment is full of physical and electromagnetic interferences. Thus, rugged enclosures should protect all sorts of things, including wires, circuit boards, sensors, and antennas. A lot of stress testing is done to check how they withstand typical EMI and physical interferences.
• For safety, any failure in automotive electronics can cause dangerous situations. So, there are multilayer redundancies and fail-safe designs in critical systems, including telemetry or control. One must carry out thorough evaluations of these systems to identify all possible single-point failures.
• Manufacturing yield can be improved by using modular designs and off-the-shelf components in Arduinobilized vehicles. One must conduct research to know how effective they are.
• Telemetry devices that track specifications, car location, and driver information can be embedded into most cars. They will be used for monitoring and insurance purposes. However, one must ensure that personal information not meant for external transmission is securely protected from any possible breaches during project development. Reports have to be confidential and securely organize them.

Key features, functions, and specifications of car arduino products

Features

• Multiple I/O ports: Arduinos are equipped with analog and digital ports that readers can use to connect sensors, motors, cameras, and other peripheral items.
• Sensors: Things like GPS, ultrasonic, infrared, pressure, temperature, and humidity sensors monitor the movement and state of the car.
• Wireless communication: Modules like Bluetooth, GSM, and Wi-Fi are included so that mobile, Internet, or inter-device communication can be achieved.
• Power supply management: The Arduinos are developed to take electric power from automobiles through voltage regulators and provide stable electric power in their units, even at voltage variation levels.
• Real-time processing: They can process a lot of inputs concurrently and act within milliseconds. For this reason, they are suitable for embedded control applications.
• Programmability: It is possible to write different applications with distinct purposes and upload them to a board via USB.

How to install

• First, the person needs to ensure that the android related to the vehicle is compatible.
• Use the provided mounting hardware and bracket to firmly secure the Arduino to the dash or inside of a console.
• It is important to make sure the power supply management of the vehicle is reasonable and avoid overcharging or undercharging the Arduino.
• Connect the input or output devices, like sensors or actuators, to the pins of the board. Any sensor connected will monitor the parameters of the vehicle.
• Use OBD II connectors to connect the Arduino to the vehicle's onboard network if it is an OBD II car.

Maintenance

• Regular software check helps keep the work tasks in good shape and healthy. Look for new versions and ensure add-ons don't conflict with each other.
• Reboot the system often to refresh the memory and clear out background processes that could slow it down.
• Make close monitoring of the temperature. If the device gets too hot within the dash area, consider adding a fan to improve airflow or moving the unit to a cooler area.
• Check all connectors, wires, and sensors monthly for any sign of wear or corrosion. Clean or replace parts that have been damaged.
• Perform stress tests on critical systems, including telemetry or control, at least every six months to identify any new software bugs or performance issues.
