Rework Wltoys 104311 With Arduino Nano

In this article, I will introduce a remake of Wltoys 104311 with the following 4 points:

- Speed controller

- Adjust car lamp brightness

- Turn signals

- Additional decorations for the car body.

- Use servo to steer

The principle of operation of the car:

-The vehicle is manually controlled FSI6

-To run forward, you push the lever on channel 2 in your right hand forward then gradually increase the throttle on channel 3 to accelerate the car forward.

- If you want to back the car, you need to pull the lever on channel 2 on the right to back, then gradually increase the throttle on channel 3 to back.

- To steer you just shake the right hand lever (channel 1) to left or right

- Turn the VRA knob (channel 5) to adjust the lamp brightness

Step 1: Prepare Components

First you need to prepare the necessary components as follows:

- Motor Driver L298 Module x1

- Arduino Nano x1

- PWM Module x1

- Power Module 3A LM2596 x2

- FSI6 + FSIA6B x1

- Battery 18650 x2

- 4-cell lipo battery x1

- And don't forget the power cord <3

Step 2: Soldering Circuits and Wiring

- This is schematic of any Modules

- Use 12V source to supply bridge H

- Use 5V power to supply led and Arduino

- Use 2 PWM modules to control car light brightness

- Use 4 channels of IA6B

- You can see the details of the work done in the video I shared at the end of the post

Step 3: Redo the Steering Part

- First you need to remove the old steering gear

- Then flatten the plane on the steering part using molten plastic

- Use a file to flatten the plane

- Then mount the cover for the servo

- Finally, insert the servos and mount the steering part of the vehicle into the servo.

=> You can see the details of the work done in the video I shared at the end of the post

Step 4: Adding Car Lights Is Redesigning the Car Body

- Use red led to make back light

- Use yellow LEDs to make turn signals

- Add fuel tank and spare wheel

Step 5: Programable

Use Arduino nano ATmega328P.
