I've been having trouble with my Arduino-- I have two components, a brushless motor and a sensor. The motor is to activate once the sensor detects something and sends a signal to the Arduino. However, there is only 1 5V port on the Arduino and both components require a 5V. Should I just connect them in series on a breadboard?
Thanks in advance.
Connecting them in series would work, that's what I've always done.
Please learn the difference between serial and parallell connection! You use the wrong terminology.
By the way, don't ever run motor currents via a bread bord. It will get damaged, burned....
Don't ever use the Arduino 5 volt to power motors, solenoids etc..
Use a separate power line for such loads. The tiny strips on the Arduino board handles low currents like 50, maybe 100 mA, not more.
It depend on the project. To connect 5 V devices, you connect them with the same + 5 V "rail" line , you connect in parallel. same with a GND "rail" line.
A series connection ... --- resistor --- resistor --- resistor ---
A parallel...
1 --- Resistor --- 1
1 -- Resistor -- 1
1 -- Resistor -- 1
In your case ...
BUT ... the motor use lots of currents and may damage the USB power supply ... So a separated + 5 V power line will be use instead for the motor, the sensor can stay with the USB power line, and both devices will share the GND in order to work properly.
Which Arduino? There are many Arduino boards.
If an Uno, there are more than one place to get 5V. There IOREF pin on the power header has 5V for low current applications. The 2 ICSP 6 pin headers each have 5V and ground pins available.
And listen to @Railroader and @sergetechone, your motor needs a driver (transistor or H-bridge motor driver) and an external motor power supply. No Arduino will directly drive a motor.
It ISNT a port, and cant power your motor.
Are we supposed to guess what they are, or could you provide more information - and a link?
