Hello, I am about to begin my first
electronics project with an arduino Uno R3.
After much research I am still a bit confused
on the circuit for the battery. I will be using
the arduino to control 4 micro servo's, an
LCD(with I2c back pack), and a HC-SR04 sensor.
I know that I will need to run the power from
the batteries directly to the servos. Will I
also want to do the same for the other devices?
I know I will also need to regulate the power
supply. I plan to use a 6v Nimh battery pack,
which leads me to my next question. I know the
arduino manual states 6v minimum input. I have
been told however, that I will want to use a
minimum 7.2v Nimh battery. Is this true?
Lastly, when I make the battery circuit do I
want to run the positive supply to the
arduino's VIN pin? If this same circuit that Is
powering the devices is regulated down to 5v
before it reaches the arduino, will it be too
low to power it?
I apologize for my confusion and I appreciate
all advice. I have attached a fritzing schematic to demonstrate what I have in mind.
