LEDWIZ Resistor question.
(1/2) > >>

My friend and I installed the LED's and the LEDWIZ last night and we had a question. In the directions it says you need 100ohm resistors placed in line where it hooks up to the ledwiz numbered ports, not the 5v line(if that makes sense).

My friend knows electricity pretty good and he looked on the NovaGem LED's I got from GGG and he is saying it appears there is already a resistor on the LED board. He wanted me to ask if that really is a resistor and if so do we need to add extra resistors?

The part of the board I am talking about is just above the solder points. It is a small black recantgle chip that has 15R0 in white letters on top of it.

Thx

The Nova Gem Coin Lamp/Switch connects to 5V directly so it has to have a dropping resister built in unlike the bare LEDs.   I have 2 of the units and they work and look great.

The 100 ohm is just an example for an LED with a 3.2 voltage drop.   Each different color LED has a different voltage drop so for example other resistors such as 150 ohm are used on other LEDs.     If you are using separate or all in one RGB LEDs do the calculation on each separate color.

A typical RGB resistor Forward Voltage (RGB): (2.0, 3.2, 3.2)V

So GB use 100 ohms and R is 150 ohms.

Ok so your saying those are resistors built onto the board??
BobA:
On the coin switch yes the resistor is on the LED board.

Ok I confused. The coin switch?

The led's I have are the NovaGem pushbutton's. They all look exactly the same.

I dont recall ordering a coin switch LED?
