radio circuit diagram

This example describes the use of HS101 and HS201 radio transmitter and receiver modules to control rotating color lights, functioning as a multi-channel radio remote control device suitable for small dance floors or home use. Users positioned at any corner of the hall can easily manage the color and brightness of the lights with a remote control. The transmitter circuit diagram consists of coded radio transmitter module integrated circuits IC1 and IC2, which form the core of the device. The radio receiver decoder controller, primarily composed of the radio receiver module circuit IC3, decoding integrated circuit IC4, thyristor switch, power supply, and other components, is depicted in another diagram. The transmitter circuit is relatively simple, requiring only a few external components aside from the integrated circuits and application-specific modules. It features five control buttons: SB1 to SB5. SB1 controls the rotation of the lights, allowing them to start and stop; SB2 and SB4 control the color of the light, adjusting brightness levels; and SB5 is the lights-out button, which turns off the lights. The color changes are achieved by varying the intensity of red, green, and blue components, allowing for a rotating color palette. IC1 manages a control range of approximately 18 feet, ensuring that the receiver decodes the data correctly. The design prevents interference from multiple transmitters by utilizing unique user codes. R2 serves as the external oscillator resistor for IC1, while the output from IC1 feeds into the radio transmitter module IC2, which modulates the signal for transmission at a frequency of 280 MHz. The power switch SA controls the transmitter's operation, indicated by the working light VL. The receiving device decodes the signals sent by IC2, amplifying them and restoring the original pulse for identification. IC4 compares the received signal with the stored user code, enabling the corresponding output. For example, pressing SB1 results in a high output from IC4, activating the motor M for rotation. The system allows independent operation of the lights, meaning they can function regardless of whether they are lit. Each button press sends a trigger pulse to control the brightness of the lights, with SB2 providing maximum brightness, SB3 medium brightness, and SB4 minimum brightness. Buttons SB2 and SB4 cannot be used simultaneously to control three lights. Pressing SB5 disables all outputs, turning off the lights. The receiver is powered by a 220V AC supply, which is stepped down using transformer T, rectified by a bridge rectifier, and filtered by capacitor C3. The remote code utilizes the HT6310 specific integrated circuit, implemented using CMOS technology.

The schematic for this radio-controlled lighting system incorporates several key components to ensure reliable operation. At the transmitter side, the IC1 and IC2 work together to encode the control signals. IC1 generates the necessary control signals based on user input from the buttons, while IC2 modulates these signals for transmission. The use of a simple external resistor R2 helps maintain the stability of the oscillator circuit, ensuring consistent signal generation.

On the receiver side, IC3 receives the modulated signals transmitted by IC2. The internal amplifier within IC3 boosts the signal strength, allowing it to be effectively processed. The decoding function is handled by IC4, which verifies the user code and triggers the appropriate output based on the button pressed. The thyristor switches (VT4, VTH1, VTH2, VTH3) are crucial for controlling the power delivered to the lights and the motor, enabling smooth operation and brightness control. The design ensures that only one light can be controlled at a time when managing color brightness, preventing any potential conflicts in operation.

The power supply section, featuring a step-down transformer, ensures that the receiver circuit operates safely and efficiently at lower voltages. The bridge rectifier converts AC voltage to DC, while the capacitor filters any ripples, providing a stable voltage supply to the circuit. Overall, this schematic design offers a versatile and user-friendly solution for remotely controlling color lights, making it ideal for various applications in entertainment and home environments.This example describes use of HS101, HS201 radio transmitter and receiver modules made of radio-controlled rotating color lights, it is essentially a multi-channel radio remote control device codes for a small dance floor or home use. Users stand on any corner of the hall can be easily controlled with a remote control light color and brightness.

T he transmitter circuit diagram is shown in Figure a, which consists of coded radio transmitter module integrated circuits IC1 and IC2 constitute the core of the device; radio receiver decoder controller is shown in Figure b shows, mainly by the radio receiver module circuit IC3, decoding integrated circuit IC4, thyristor switch and power supply and other parts circuit. Relatively simple transmitter circuit, in addition to integrated circuits and application-specific modules, the external components small.

It has five control buttons SBl a SB5, SB1 is to control the rotation of the key light, press about, rotating lamps, and then press about, the rotation stops; SB2 SB4 is to control the color of a light but ton, the button is pressed, respectively, , can control the lights of a color in the most light, medium light and darkest; SB5 is a lights-out button, press this button, the lights go out. The principle is to change the color of red, green, and blue shade brighter than to achieve, but also can be rotated to change the light color palette.

IC1 15 yards for a 18 foot control for the user side, the high and low level (ie, ground pin, which of) the receiver must decode the data controller is exactly the same when the user code can only remote control, the aim is to achieve at the same venue How different is only the transmitter control both the receiver, because of user code data of different interference will not occur. R2 is the external oscillator resistor IC1. 11 feet from the output of IC1 anyone to the radio transmitter module coded pulse the input side IC2 IN, modulation of IC2, IC2 through the built-in antenna for the 280MHz frequency firing in the air around the radio waves.

When you press the SB2 time, IC4 pin 1 output trigger pulses to VTH1 conduction through B5, as this pin turns the output pulse angle of the largest, ELI maximum brightness; When you press the SB3 when, IC4 of 18 feet, the output trigger pulse, the R6 to turn thyristor VTH2 medium, EL2 medium-brightness light hair; when pressed SB4 time, IC4 output trigger pulse of 17 feet, so VTH3 opened by R7, the output pulse because of the foot conduction angle minimum, so the EU made low light. SB2 SB4 is the interaction of a non-independent, that is, any time can only control three lights in any one, not simultaneously control 3 lights.

When pressed SB5, IC4 of 1, 17 and 18 feet without the trigger pulse output, ELI had a E13 due to the AC zero and all off. Receiver power from the 220V AC step-down transformer T, a bridge rectifier VDl VD4 and filtered by capacitor C3 voltage supply.
