Remote control cars have always been an attraction for kids. Even as adults, you can’t outgrow them. These remote control cars operate on special type remote control circuits. However, these remote control toys are available in the market in wide ranges. However, designing these circuits and manufacturing them on your own gives another type of experience. But it’s quite a difficult and complex process to assemble various types of electronic components. Or you may get confused in the middle of the process, and you may stop it.
Therefore, to make this process easy and communicable. We provide you with detailed information about how you can make a remote control circuit for your remote control cars with just one printed circuit board and some essential components.
What are Remote Control Circuits?
A remote control PCB as the name suggests, can operate the device remotely, even from a distance. It has wireless connections. But some may also contain wired connections. These remote-control PCBs can be used in LEDs, LCDs, TVs, DVD players, and various types of toys. Devices that contain RC circuits imply that you can use and operate the device freely.
However, these devices can only operate just from a very short specified distance. Otherwise, it won’t work. Some advanced devices with advanced circuits can operate from far, like drones, but some devices use only short circuits that only operate within the specified range.
Additionally, some devices with old generated RC circuits, like televisions of early ages, use ultrasonic tones. However, devices with the latest RC circuits can use IR remote control, which uses IR digitally coded signals to control the devices.
IR technology helps in controlling various types of circuit functions along with speed and power. Moreover, some remote controls are specially designed with special types of circuits and can act as universal remote controllers that can work in almost all types of circuits.
Working on Remote Control Circuits
Playing with RC cars looks fun. But how it works and operate amaze you the most. These types of RC cars and devices use radio signals. The transmitter creates these signals and sends the signal to the receiver present in the remote car. These signals, however, operate the car perfectly.
When a signal reaches the circuit receiver, it identifies and translates the code into desired mechanical action of the car. This is the surface phenomenon a person sees or understands. However, RC cars have more functions inside of them that make them operable.
In RC cars, the transmitter sends radio signals to a receiver. It uses a specific range of frequencies using a controller. The signal operates through the battery power of the car and controls features like forward, reverse, left, and right. Moreover, touching the controls creates an electrical connection that transmits and connects some specific pulses. The specific pulse quantity is based on some specified actions.
When a car receives these electrical pulses, it eventually turns that specific part of the car. Furthermore, to enable all these functions, a remote control car needs a motor and an RC circuit board. In addition to this, always remember that the receiver always waits for the signals to receive. Therefore, it fulfills your command instantly at once.
Making of A Remote Control Car Circuit
The manufacturing process of remote control cars needs various types of electronic components and devices that play an essential role in the functionality of RC cars.
· Transmitter
The transmitter acts like the brain or central processing unit of RC cars. It refers to a manual controller that helps in transferring signals to the receiver by pressing manual buttons. Moreover, they work similarly to the remotes of televisions.
· Receiver
Remote control cars need receivers. This receiver catches the signals from the transmitter. Firstly the receiver receives the signals and then decodes them into mechanical form. You can also say that receivers here act like antennas.
· Motor
Remote control cars need a special type of device that is responsible for all their movements. Motor serves as that very crucial part. It manages all movements of a remote control car. Moreover, you can also install various motors in one car based on your needs and preferences. However, if you really decide to utilize two motors, then make sure to grant different duties to both motors. Make sure one motor moves the back wheels while the other one front wheels. Furthermore, some older remote control cars also use four motors in which each controls one wheel.
Another important factor in installing the motor is to choose the right one. Basically, the type of motor depends on the type of remote car you are going to make. Large remote cars use a 12V DC motor as it carries heavy loads all at once. However, small remote cars use 6V Bo motors.
Considering the RPM is also a very important factor when choosing the right motor. RPM refers to how many times a shaft of a DC motor completely spin in one minute.
The spin cycle contains a 360-degree turn. However, make sure to choose the motor that has low RPM, as it will be easy for you to manage them. Moreover, you must remember that both the torque and speed of a motor are inversely proportional to each other.
· Power Source
Remote control cars operate on power sources just like any other fuel cars. The majority of remote control cars use batteries as a power source. These batteries provide electrical power to receivers, electrical motors, and electrical components. Moreover, other than batteries, some remote control vehicles use a nitro engine to operate. This nitro engine uses fuel rather than batteries.
· Circuit Board
Circuit boards serve as the core component of a remote control car. It identifies different electrical charges and signals among different components of the remote control car.
· Servo
Servo plays a crucial part in the layout of remote control cars. It helps in converting the power source electric current into movement. Additionally, it is generally responsible for operating remote control vehicles’ steering systems. Also, the servo enables the remote control vehicles to move in the desired direction.
· Speed Controller
This electrical component keeps the remote control vehicle’s RPM and speed in control. Remote control cars that operate on batteries use an electrical speed controller component in them. At the same time, remote control cars that operate on nitrogen engines utilize throttle servos in them.
Conclusion
After reading the whole article, you have clear ideas about why remote control cars are still famous. Besides this, how these cars work and some important parts that make this cars.
