PURPOSE:To enable a toy to travel smoothly in a three-dimensional indoor space by providing a radio control circuit which generates false proportional control signals to linearly raise the number of revoalution of a motor in response to manipulation of an ON/OFF button of a transmitter. CONSTITUTION:A CPU 14 produces specified pulse data corresponding to ON/ OFF signals of a joy pad, and sends the pulse data according to a transmitting method such as PM, PCM and others. An amplitude detector 13 extrancts the pulse signals from received signals, and the CPU 14 deciphers the pulse data and sends motor control signals, forward/backward control signals and others to a driver 10 based on the results of decipherment. A motor driver 17 is connected to the CPU 14 and drives a direct current motor 16 at a number of revolution corresponding to false proportional control signals or turbo control signals. Thereby, variable linear inputs similar to those by a joystick can be done by simple ON/OFF key manipulation. |
