Infrared remote control four wheel car

Introduction

Today we use a 8-channel relay module to make a four-wheeled car. When press 4 keys(2,4,6,8) on the remote control, and you will see the car forward, back, left and right.

Experimental Principle 

The 1838B IR Receiver is a 38KHz IR receiver that can receive signals modulated by a standard 38KHz remote control. By programming the Arduino UNO R3 board, we can decode the signals.

In this experiment, by programming the Arduino board, we encode the data received by the IR Receiver that is sent by the remote control, and display the deciphered data on Serial Monitor via the serial port. In the program, we use the Arduino-IRremote-master library (provided).
Note: 
Before using this library, you have to delete the RobotIRremote directory in your Arduino IDE directory (check in IDE by File->Preference, and see the path in the Browse dialog box), and delete the RobotIRremote directory in the system Documents folder. For example, if your computer is running on Windows 7, you need to delete the RobotIRremote
Directory in
C:\ProgramFiles(x86)\Arduino\libraries and C:\Users\SJG\Documents\Arduino\libraries.
Otherwise, when you compile the program, errors will be prompted.

This is a 5V 8-channel replay interface board which is able to control various appliance, and other equipments with large current. It can be controlled directly by Microcontroller(Arduino,8051,AVR,PIC,DSP,ARM,MSP430,TTL logic). 5V 8-Channel reply, interface board, and each one needs 15-20mA driver current. It equippes with high-current relay AC250V 10A and DC30V 10A also screw holes to install easily.

Experimental Procedures
Step 1: Build the circuit

Step 2: Install the function library (Arduino-IRremote-master.zip).
