The electronic circuit "Flashing LED" by YuGiOhJCJ[1].<br />Music "Cockpit view" by Poisoncut[2].<br />Thanks to PA5CAL on Futura Sciences forums[3].<br /><br />I use some resistors, capacitors and transistors to make my light-emitting diodes flashing.<br />In fact, this electronic circuit without LED is called "Astable multivibrator".<br /><br />I heard that there are others solutions to make light-emitting diodes flashing :<br />-using directly a flashing LED<br />-using the NE555 integrated circuit<br /><br />[1] http://yugiohjcj.1s.fr/<br />[2] https://8bc.org/members/poisoncut/<br />[3] http://forums.futura-sciences.com/
