Need Help On car steering (Toy)

[amilabanuka]

Hi guys.
i need help to make a steering mechanism for a toy car.
the car should be able to drive forward and reverse and can be turned. car should be controlled by a wired remote control with maximum of 3 wires.
this seems to easy, but I'm still in the first year and do not have knoledge about these stuffs.
my main problem is how to make a steering mechanism and how to manage control with 3 wires.

buy a motor attached to a gearbox for extra torque, one way is spring loaded to return to center with a flat toothed bar, next is a teardrop gear with rubber band slippage, next would be a spiral gear with no springs. as far as the wires go you'd have to have a split supply and use dpdt spring return to center switches wired with the outer poles forming an x to change polarity.

Hi there,

Making a steering mechanism for a toy car can definitely seem daunting, especially if you're new to this type of project. However, with some research and guidance, it is definitely achievable. Here are a few tips to help you get started:

1. Research different types of steering mechanisms: There are various types of steering mechanisms used in toy cars, such as rack and pinion, worm gear, and bell crank. Research each type and decide which one would work best for your project.

2. Use a servo motor: A servo motor is a type of motor that can rotate to a specific angle and hold that position. This is perfect for controlling the steering of your toy car. You can use one of the three wires from your remote control to connect to the servo motor.

3. Consider using a motor controller: A motor controller is a device that allows you to control the speed and direction of a motor. This can be useful for controlling the forward and reverse movement of your toy car. You can use the remaining two wires from your remote control to connect to the motor controller.

4. Use a simple circuit: To manage control with only 3 wires, you can use a simple circuit that includes a switch and resistors. This way, you can use the same wires to control both the steering and the movement of the car.

5. Get some help: If you're still struggling, don't be afraid to ask for help from a teacher, friend, or family member who has experience with electronics. They can guide you through the process and offer valuable advice.

Good luck with your project! With some determination and a little help, you'll be able to successfully create a steering mechanism for your toy car.
