1. A method for controlling an electronic scale to measure and indicate an external force, comprising:
detecting the external force by a weight sensor; and
driving a prompting device to emit a first color light with a switching frequency along a route by a controller until the external force detected by the weight sensor reaches a first weight;
wherein the prompting device comprises a plurality of light-emitting elements arranged in the route for emitting the first color light sequentially with the switching frequency along the route, while the external force detected by the weight sensor increases until reaching the first weight.
