Powering your projects
Your project may need different voltages depending on what your plan is. Whether you plan to light up an LED, or run a motor, activate an electromagnet, or use a sensor, run a micro-controller you will require different voltages and currents. You might also require many different voltages simultaneously.
9 Volt Battery (1.5 V x 6 cells)
Rechargeable Pencil Cells
Creates 1.2 Volts
Battery Charger
You can make different voltages for a 1.2 Volt cell by connecting them together
2 Cell holder
Creates 2.4 Volts (1.2 x 2)
4 Cell holder
Creates 4.8 Volts (1.2 x 4)
Solar Panels
Our panel creates 3V and 6V
Solar Power Panel
We have Solar Panels in the lab which can produce 3V (small panel) and 6V (large panel)
DC to DC converters
What if you have to run your project at a location that does not have any power supply? You will definitely need a battery or a solar panel. And what if the battery is just not having the right voltage for your project? To Find more about these devices click on this link
Example: What if you have a 9 Volt battery but you need 7 Volt only?
What if you have a 1.5V battery but need 5 Volt for arduino?
What you will require is a DC to DC converter. It will do the job for you by increasing (boost) or decreasing (buck) the battery voltage
Power Adapters
You can plug these adapters into any Wall socket (AC) to produce DC Volts. It also comes with many different types of Connectors Tips to match with any type of equipment you may want to power up
AC to DC Power Adapter
Creates 12V
AC to DC Power Adapter
Creates 5V
Especially useful for Powering up Arduino boards
Power supplies to use when you are prototyping with electronics in the ATL
WorkBench Power supply
This power supply can create Anything between 0 Volts to 30 Volts. Actually this one has two such power supplies in one unit. Hence it is called a Dual power source
SMPS
SMPS stands for Switch Mode Power Supply. You will find these boxes inside of computers. Once they are connected to the wall socket (AC) they can produce just the right voltages (DC) to help power up to all the different parts in the computer. This SMPS can be also used to as a power source for your project. Click here for more details
Supply from USB Port of the Computer

Different types of USB connectors
All supply 5V
Bread Board Power Supply
These Gives 5V and 3.3V as output. These are very useful voltages for powering up most of the micro-controllers. They snap into the breadboard rails. These power supplies are meant for experimenting with circuits on bread board. It requires a AC to 12V DC Adapter to power it up. It cannot deliver high current (< 700 mA) but enough to drive the micro-controllers. Click here for more details
