How to work with BCD(binary-coded decimal) switch?
--entry is still in work--
How does it work?
A BCD-Switch is actually not one switch, it contains basically four switching circuit at once. There is a wheel which closes depending to the number the switch shows in the front. The picture on thr right are 5 BCD switches stacked sideways together.
What will you need?
- an Arduino (every typ will do)
- a BCD-Switch
- a shift register (CD4021)
- jumperwires
- a breadboard
