Re: Leds using a old servo board question
I have used the servo boards a lot it works fine but I add a resistor to each LED the rx olnly puts out 6vdc so there is a simple chart for the value of each LED
Color resistor value Voltage Drop (V) Red 200ohm 2 Green 195 ohm 2.1 Blue 120 ohm 3.6 White 120 ohm 3.6 Yellow 195 ohm 2.1 Orange 190 ohm 2.2 Amber 195 ohm 2.1 Infrared 215 ohm 1.7 Other 200ohm 2 I got this info from https://www.allaboutcircuits.com/too...or-calculator/ also I have saved myself a bunch of time by using single pass rc switch https://www.aliexpress.com/item/RC-L...ceBeautifyAB=2 you do not need the board unless you are using it as a switch. you can run direct to the battery port on the rx . I only use the 200 ohm resistors for everything some difference in light output but it is minimal hope this helps Last edited by Nikaem; 01-28-2018 at 12:34 PM. |
