If you are a fan of DIY, you are probably familiar with the Tower Pro 9g servo. It is a common servo that is used in many different projects. However, if you want to make your micro RC truck as small as possible, you can use a smaller version of the servo, such as the 3.7g servo. This servo measures just 20.2 x 8.5 x 20.2 mm (0.80" x 0.33" x 0.80") and weighs only 3.7 g (0.13 oz) without its 15 cm (6") lead.
In this project, we will use two servos: one for the steering system and the other for the engine. We will also use a custom Bluetooth receiver module to allow for easy and reliable control of the truck. The smartphone app provides a user-friendly interface for controlling the truck, and you can even customize the app to suit your preferences.
To get started, we will walk you through the entire process of building the micro RC truck, from assembling the chassis to installing the motors and connecting the Bluetooth receiver module. We will also show you how to program the smartphone app to control the truck's movements.
The first step is to assemble the chassis. This can be made from a variety of materials, such as acrylic or plywood. Once the chassis is assembled, you can install the motors. The motors can be attached to the chassis using screws or nuts.
Next, you will need to connect the Bluetooth receiver module. The receiver module will be connected to the motors using a small cable. The receiver module will allow you to control the truck's movements using your smartphone.
Finally, you will need to program the smartphone app. The app will allow you to control the truck's movements, such as forward and backward motion, steering, and even custom movements.
We have provided detailed instructions for each step of the process. So, whether you are a beginner or a hobbyist, you can follow along and build your own custom Bluetooth-controlled micro RC truck.
We hope you enjoy this project!
