Rc car circuit board with remote

Posted on 09.01.2021 Comments

Whether you are an engineering student building a multi terrain vehicle or an electronics hobbyist trying to impress people with your skills, making a RC robot car wireless is much better than the wired robot which you will have to tail while driving.

This is not exactly a robotics project. By definition, a robot is something that makes a decision based on some external parameters. Well not exactly nothing, but nothing complex. As I mentioned earlier this is a really simple project, so simple that not even have an embedded computer microcontroller in it. The emphasis is just on the mechanical design and some basic circuitry. Most of the components that we will be using are really common and can be bought in local electronics stores.

Here is a list of all the hardware items that you will need for this project. And in terms of electronics, you will need the following major components. You may also need some other basic components such as resistors and capacitors but we will discuss them as and when we get it.

Other than the above components, you will need a basic supply of tools, soldering iron, and related stuffs. Here is a flowchart to help you understand the working logic of the robot car. First we will go over the basic idea of the RC car and the working logic that is involved in the car. There are two blocks, the Transmitter remote control and the Receiver robot car.

On the transmitter side, you have the switches to give the digital inputs to the encoder IC. The encoder then encodes this data and sends it to the the RF Transmitter module.

On the receiver side, you will have the RF Receiver which receives the encoded data and passes it on to the decoder. The decoder decodes the data and sends it to the motor driver IC to drive the motors. The next step is to learn how to access the data sheet for the components that you are using.

Its actually not that big a deal, just Google the component name and you will find links to the datasheet. The data sheet or spec sheet is a PDFA document that is provided by the manufacturer to give us a better understanding of how the component actually behaves.

The real tricky part is to find what you are looking for in the PDF file that you just downloaded. Reading and understanding the data sheet is a skill that any electronics enthusiast should master.

I suggest you read the article Are you reading the datasheet? What to look for and how to find them! So the point is spend enough time with the datasheet. There are a lot of different types of drive algorithms for driving robotic cars. One such method is the differential drive method. We will be using only one pair of motors to drive the car. Check out he video for seeing how the hardware is connected.

We will just have one castor wheel asides from the two motors and it will be used to give mechanical stability to the robot car.

Now the obvious question is how will the car change direction if it has only two wheels. That is when the differential drive algorithm comes in the picture. The direction control is achieved by rotating one of the wheels in one direction and the other in another direction. The following table might give you a better understanding. As you should have guessed, the car will go front or back if both the pair of motors operate in one direction and left or right if they operate in different directions.

Now here is what the RF transmitter and receiver modules will look like. Even the frequency in which they communicate should not be a problem as long as both the receiver and the transmitter are of the same frequency.Make any battery-operated toy car remote controlled using this circuit. To operate the toy car, you need to hold the transmitter in your hand, keeping it pointed at the toy car which has the receiver fitted inside, and simply press a switch provided on the transmitter.

In the transmitter circuit, there are two astable multivibrators. The first, built around transistors T1 and T2, produces a frequency of about 1. The second, built around transistors T3 and T4, produces about 38 kHz. The amplified signal is further given to relay-driver transistor T7. Relay RL1 energises to control the toy car.

Working of the circuit is simple.

Transistor T6 cuts off and transistor T7 conducts to energise relay RL1 and move the toy car. Assemble both the circuits on separate PCBs. Keep the 9V battery inside the cabinet. Fix switch S2 on the body of the car and the relay inside the car. Use a 6V battery to operate the toy car receiver unit. Sign in Join. Sign in. Log into your account.

A version of the RC Car that uses Remote Arduino to allow a Windows device to control the motors without using an external motor shield. Since this project is proprietary for this specific car's PCB, you may want to refer to the motor shield solution if you are using a different RC car.

In this project, we will modify an RC car to allow it to be controlled using Windows Remote Arduino via a Bluetooth connection! With Remote Arduino, it is possible to build a Universal Windows Application which will direct the car in any direction. We used a Lumia phone running Windows 10 to control the car with the built-in accelerometer! You can download the "samples" repository here. This sample is "remote-controlled-car" inside the Win10 folder. Make sure to clone the repository recursively so that you also obtain a copy of the library more info in the readme!

If you'd prefer to create your own project, follow the project set up guide here. You can find the Windows Remote Arduino repository here. That is the last of the hardware setup steps!

You can now screw the circuit board back on. You may also want to secure the Arduino don with zip ties in the area above the rear motor.

Download the sample repository here. You'll find "remote-controlled-car" inside the W10 directory. This sample uses a Windows 10 phone's accelerometer to drive the car! Currently, the sample is set up to launch ControlPage automatically when you connect to the car via Bluetooth. Since the controls are different for the different boards, you'll want to make sure you are using the Maisto Control Page.

If you are using a different pin configuration to control the motor shield, you'll want to locate and change the pin values for the following variables inside ControlPageMaisto. Or just modify the source to use the default zero-argument constructor of BluetoothSerial which will attempt to connect to each Bluetooth device you are paired to until it is successful with one.

As usual with Windows Remote Arduino, you only need to program your Arduino device to run "StandardFirmata" you can find this in the "Firmata" folder in the included libraries. Just make sure to change the baud rate in the sketch to match your device. The BlueSmirf runs at by default. Please log in or sign up to comment. Project tutorial by Team Windows IoT.

Project tutorial.Add the following snippet to your HTML:. Want a cheap and awesome smart robot car? Why not buy an RC car and convert it? This project shows how to hack the hardware and get control.

Read up about this project on. Troy first came up with the idea of hacking the hardware on an RC car to get control of the motor controller circuits as a way to get an inexpensive and fun car chassis, motors, and controller to build a smart car robot. One can buy the kits with motors, chassis, and wheels, however, they are challenging to assemble and slow compared to these cheap RC cars.

This is not the first time it's been done, but, this time we will take it further and use a Cypress PSoC controller to make the brains of the robot. Fortunately for us, most of these RC cars use a common H-bridge motor controller. The first installation of this project shows how to hack the hardware motor controller to get control of the signals that control motor direction and steering.

Buy from Newark Buy from www. Typical RC car motor controller This is a schematic for the typical motor controller board on an RC car.

The partial rectangle on the left is the integrated circuit that feeds electrical signals from the remote control to the motor controller. I drew circles around the electrical nets from the integrated circuits where we will hack into the motor controller and disconnect it from the remote control decoder integrated circuit.

I removed "R13, R14, R15, and R16" from the motor controller board to disconnect the on-board remote controller integrated circuit. In the next schematic I will show how I took control of the motor controller using switches.

Remove resistors from RC car motor controller board This is the motor controller board in the RC car. You can see power from the batteries coming to the board on the brown and black wires, rear wheel wires are blue and white and front steering wires are red and black.

The important thing to notice are the resistors R6 and R4 along with two other resistors covered up by the black wire from the switch. I was able to determine that those four resistors are the equivalent to R13, R14, R15, and R16 on the schematic. I used a volt meter to look at the voltage output from the remote controller integrated circuit to the resistors and then by flipping the controls on the remote controller determine which resistor performed which function.

Then, I removed the tiny resistors with a soldering iron tip being careful not to damage the pads on the circuit board. Wiring to the motor controller board Now you can see how I soldered the green, yellow, white, and orange wires to the transistor side of the motor controller completely disconnecting the remote controller integrated circuit outputs from the motor controller. Then you can see each switch and the voltage dividers and current limiter.

When the switch is not pressed, the base of the H-bridge transistor is grounded through a 10K resistor and turned off.A premium membership for higher-level suppliers. Fast Delivery. MOQ: 1 Set.
