Hi, I am a newbie with Arduino. I am trying to build a Line bot, but it is not working. I read a lot of information on the web but nothing solve the issue. The issue is basic, the board and the robot works fine when it is connected to the USB cable and the computer but as soon as i disconnect the USB from the computer and run with an external power supply the …
Charge the battery for 10-12 hours or until it is fully charged. Can I Use a Switching Power Supply to Charge a Battery? Yes, you can use a switching power supply to charge a battery. However, there are some things to keep in mind when doing this. First, the voltage of the power supply must be higher than the voltage of the battery.
Basically, the PSP do not recognize batteries, which are proven to work on another PSPs, though PSP works when connected to wall socket. Well, in nutshell: - PSP works while connected to power outlet - PSP does not even start when on battery.
The removable battery of your HP notebook might not hold a charge due to a faulty power supply or AC adapter and might need to be replaced after testing all components. Unplug the AC power cable from the notebook, and then remove the notebook battery. Plug ...

This is not programming related or software problem but please help me… I''m making home automation with power consumption monitoring. I do have 5v relay and 3 bulb. I want to use external supply which is 5v 2A but it won''t work, the template says offline. I know this a supply, circuit or wire problem but what should i do?? What is needed to make it work? If …
I tried to remove the battery and run but it does not run without battery. I purchased a new battery (not original, since HP stopped producing old batteries) but it does not boot with it (even it is the SAME 7.7V - 41W). I now returned the old battery and the laptop is

Yes, you can simultaneously connect external power supply and USB. As explained in one of the answers, that you linked, the Arduino chooses it''s power input through the supplied voltage on Vin/barrel jack. Vin has no direct connection to the VUSB, so the USB ...
Hi everyone, I''m working on a project that uses the hardware serial interface of the arduino uno. The problem that I''m having is that everything works when I power the arduino via the usb port, but when I only use an external power supply the serial communication stops working. I googled about this issue and found out that it has to do with the bootloader that on …
That type of problem is usually caused by the external power supply not ramping-up quickly enough and the the CPU missing the RESET signal generated by the …
Troubleshooting - Device''s Battery not supplying power/charging, Battery not charging to full, Unable to power on via battery Applicable Products: Notebook, Gaming Handheld If you are facing issues with the battery not supplying power, not charging, or not charging to full capacity, please follow the troubleshooting steps below:
External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board''s power jack. Leads from a battery can be inserted in the GND and Vin pin headers of the POWER connector.
Connecting or disconnecting the USB supply in this case will not make a difference, so you can have both power supplies connected simultaneously, only when the power input drops below the specified level (about 6.6V+0.6V=7.2V), the USB will start powering
It was connected to a external 12V power supply on the 2.1mm plug. A single digital output was connected to a base of a BJT, which was being used as a switch. I checked all the voltage differences and amount of current around the BJT with my multimeter, and I made sure nothing ever exceeds the maximum rating.
Battery power can also be utilized, with various types available, such as 9V batteries, AA or AAA battery packs, or even lithium polymer batteries. Users can hook up a battery to the Arduino Uno board using the GND and Vin …
My older laptop (HP Spectre XT TouchSmart) does not have a working battery and a replacement is not readily available (relatively few options in Canada), so I''ve been using AC power directly. This is very inconvenient when I need to be mobile. I''ve looked into ...
Hi, i''m new to arduino (and electronic in general). I read that it''s possible (on Arduino) to use external power (with the jack) and the usb at the same time, but i couldn''t find if on Freaduino Mega2560 is. The wiki says: "The Arduino can be powered via the USB connection or with an external power supply. The power source is selected automatically. External (non …
The topic has come up several times already here on the board, but has never been answered, so I will describe it again: I upload a simple program via USB while powering the Arduino board with an external 9V power supply. The program runs (LED connected to Pin 13 blinks). I unplug USB. The program still runs, LED continues to blink. Everything fine up to …
For laptop users, external power supplies are the norm, but a lot of times the power supply the laptop comes with is not efficient enough especially when it comes to a gaming laptop. With an external power supply, you can easily transport these around wherever you''d like and the weight of the device isn''t much more than a pound or two extra to carry.
I have a 5V and 12V Super rechargeable Li-ion Battery, and I''m trying to power my Arduino with it. It''s an emergency because tomorrow I have to present a robot and it doesn''t work. My Arduino is an Arduino UNO R3, I try connecting the 12V power to the barrel plug
Hello, I have looked on various different threads that seem to have the same problem but it sounds like everyone is having slightly different issues then me because none of their solutions worked. (See below for threads I tried). I am trying to power an Arduino Nano on external power (5.2V). When I had the Nano plugged into the USB port on the computer, it ran …
