Very new to Electronics Fields but compelled by my obsession. I would like to start with small projects which is very necessary at my house. I will explain some of my project ideas here.
- I would like to design a DIY project using Light Dependent Resistor which controls the light (very small light- 1 Watt cool white LED) on my backyards and/ or frontwards controlled by PIR sensors. That means turn the light ON when the sensors feels something/somebody otherwise leave as it is.
- I would like to design a mobile app for a Bluetooth module that I would like to combine with Ardruino /PIC microcontroller to control the light. Since this is outdoor project, I am very much limited with Power Source.
Now, where I am bit hesitant about:
What should I use as a Power Source for my project?
I can use Batteries ( different Volts , 1.5, 9V etc) but what types of circuit I should be using so that the circuits make the battery last long or controls the battery voltage only when needed. There are many components to think about like Bluetooth module, microcontroller, light etc.
Being a beginner, I am trying to avoid High Voltage if possible. I would like to mainly concentrate on DC sides at the moment. I would be interested on elaborating my projects idea more and more but I am stuck with Power Source planning.
