ABSTRACT:
A speed controller circuit for a radio controlled (R/C) model includes a preprogrammed controller, first and second pushbutton switches, and a row of at least four light emitting elements (e.g., LEDs). The speed controller circuit is adapted to be mounted on an R/C model and to be connected to a battery, a motor, and a receiver on the R/C model for purposes of coupling power from the battery to the motor according to speed and braking information received via the receiver. The preprogrammed controller (e.g., a peripheral interface controller or PIC) is adapted to control operation of the electronic circuit under program control according to a stored setting for each of a group of operating parameters. The first pushbutton switch enables a user to select a particular parameter from the group of operating parameters. The second pushbutton switch enables the user to select a value for the stored setting for the particular parameter selected. The row of light emitting diodes display information identifying the particular parameter selected and information indicative of up to eleven values for the particular parameter selected. The group of speed controller operating parameters may relate to initial braking characteristics, neutral zone braking and zone range characteristics, throttle characteristics, initial motor current limits, and ongoing motor current limits. Labels relate the LEDs to operating parameters and values.
