A previous Design Idea describes a circuit that uses an astable multivibrator to drive an LED (Reference 1). The circuit in Figure 1 uses a simpler alternative approach. The circuit uses a 2N3904 NPN ...
The objective of the circuit is to build an electronic dice based on the functions of a 555 timer integrated circuit that operates in the astable mode. LM555 – a highly stable device for generating ...
