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

Creates 12V, 3.3V and 5V



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
