Blinking the leds on two common-anode 8-led bars

- by Floris Wouterlood  - The Netherlands  - -Summary - Leds can be controlled by an Arduino in several ways, for instance directly in a one led – one pin configuration, via arrays or indirectly, with only three pins with a shift register chip as intermediary element. This paper discusses the construction of a configuration...

Building an Arduino led cyclotron engine with shift register chips

by Floris Wouterlood Leiden, the Netherlands January 22, 2017     Summary Series of leds that light up in patterns are very attractive to the eye. Here we discuss the construction of a 'cyclotron': a circularly arranged series of 24 leds controlled via three shift register chips. There are two parts: a disc carrying the...
