This is the LED circuit diagram for the R/C car.
I roughly drew it
First, the point is two 9v rectangular batteries (Can I use one?)
Two switches- When the top is raised, only the center is turned on, and when the center is raised, only the front and rear are turned on...
Do you understand roughly?
LED is a high-brightness 5 pie
But there are 3.6 and 2v bolts
I know it was originally 1.5v, but... isn't it? ㅠ
The question is...
1. Please find the right resistance for this LED ㅠ
2. You have to attach all the resistors to the LED, right?
3. If I reduce the battery to one, is there a huge difference in brightness and lifespan? (For lighter weight...)
We ask for a lot of answers, and I would appreciate the answers to those who specialize in electrical circuit diagrams.
See the circuit diagram below.
1. Considering the battery life, method 2 is recommended.
2. Since the total current is about 80mA, it has a lifespan of about 5 hours with 4 batteries.
3. Refer to the website below for LED color, voltage relationship and resistance calculation method.
