Hi everyone. Hope you all are having an amazing day.
I am a university student, and i need your advise for my FYP. Basically i have to connect gsm, gps, fingerprint sensor and a touch screen, on a single arduino mega.
I am confused on how am i supposed to calculate which component will draw how much current and voltage from Mega.
Moreover, it is supposed to be portable so how should i power up all these things? With a battery?
And what lithium ion battery should i assemble to make it last atleast 2 days?
I hope this doesn't sound patronizing, but the entire point of an FYP is to learn how to research questions like this independently.
Were current and voltage calculations not covered in your courses? Of course, you have already consulted the specifications for each device you mention. Can you please follow the forum guidelines that are offered in the permanent threads at the top of the forum, and provide links, or post detailed information about those devices?
Also, it is not possible to offer good advice about power consumption and requirements, without knowing the use cases that will arise in the application. For example, how often the GSM module will be active (don't answer just that question, we need the whole breakdown).
The Arduino is NOT a power supply. It needs power, it does not PROVIDE power.
Every device has a data sheet with a maximum current spec. Total them all for your total draw. Size your PS at least 25% larger for "headroom". This will also give you your battery draw, and thus your battery size (ampacity) for a given runtime.
Draw a schematic and show your work thus far. We are NOT a homework service.
Your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for advice on (nor for problems with) your project.
I totally understand the purpose of FYP. But i am stuck, i need some ideas. That's when i considered approaching on arduino forum for help. Yes, ive concepts about voltage and current. But unfortunately im unable to apply them to find out which battery should i use for this project. I fear burning my components.
I do respect the fact that you first told about the purpose of FYP. I wouldnt even try to cheat, but i need help.
Hey buddy. So i am enrolled in applied physics (bachelors). I have always been into programming like programming on python, c++, VB.net, etc. Last semester we had a course called microcontrollers, and in that we learnt assembly language in depth and programmed microcontroller (8051). Thats when i had experience with programming on a micro controller.
This semester, I was selected for FYP, i used arduino Uno before for basic electronic projects. I ve now shifted to arduino mega. I can use multiple sensors at the same time but when arduino is plugged into the system. I am not sure how I should power arduino up and the components without burning them.
