Electronic guidepost is shown as the picture. Its displaying circuit consists of 24 luminous diodes which are ranked in 6 groups in accordance with the direction of arrows. Electronic guidepost uses the pulse signal generated by time-base circuit to drive the 6 groups of luminous diodes to display dynamically according to a certain regular pattern so as to indicate the moving direction. The circuit is mainly composed of time-base circuit 555, decimal counter CD4017 and display circuit.
