How to build these projects? 

 

   Using readily available modules and with help of simple, easy to follow pictorial wiring diagram, anyone can wire up an electronic system to suit their needs. With help of an electronic system your creation will become smarter and livelier.

 

Why not using a Micro-processor?

  

   Many useful application specific projects can be built without using a MCU (micro-processor unit, such as: Arduino) with the following advantages.

1. No computer and programming required.

2. Circuit has fastest response.

3. Lowest power consumption.

4. Simplest construction, less time to  build and less problems.

5. Lowest cost for the project.

6. Minimum wieght and dimensions.

7. Less problems for long term operation.

8. Gurantee to work.

 

  Following is a typical simple hook-up for a reduction of light warning circuit using a CdS light sensor module.

 

 

How a Solderless Breadboard Works?

Each rows or columm has clip contacts underside of each hole, so when wires are inserted into the same row or columm they are electrically connected together.
