'' | To accomplish the change of the number we build a two-way connection; first we put one, two and two times three LEDs each in a series circuit and connected those in parallel. Next a resistor of 330 Ohm was used for the wiring with only one LED and a resistor of 220 Ohm for the one with two LEDs. That's slightly more resistance than needed but we assumed this wouldn't be a problem. | ||
On top of this we improvised a toggle switch which connects the two LEDs either with the single LED to form the "1" or with the other six LEDs to form the "0". | |||
