Simple Electronic Projects With Circuit Diagram Can Be Free Download
Circuits diagram and schematics – Electronic projects A small collection of electronic circuits for the hobbyist For example : dc power supply,inverter,dc converter.
Simple Battery Level Indicator Description Here is a easy to build low battery level indicator circuit that produces a visible indication by flashing a LED.
How to Make Electronic Projects ?
Preparing Experimental Board for demonstration you will need base board. You can use plywood 3mm thickness of desired size. Normally we use 8/12 Inches. Paste one side with florescent paper.
Prepare Circuits
Look at the circuit diagram of your project, If having too many components then you have to use varo board also known as dot matrix board for connecting all small components using soldering iron. For few component you can directly place all components on ply and solder it by using pieces of wire.If you dont like soldering work, you can use Breadboard.
How to solder ?
First make your soldering iron temperature at the level at which it melts solder easily otherwise it will result in dry or crack soldering. For good soldering, use pointed and clean Tip. Use best Solder wire and Soldering Flux. All surfaces to be soldered should also be cleaned. Apply Soldering paste or flux at joint. Melt solder on tip of the iron and place it on the joint for 2-3 seconds. Your component will get connected perfect.
Tools for Making Electronic Projects or Circuits ?
General Tools for getting started with all Electronic Projects work are :-
Soldering Iron 25 Watt, Screw Driver, Tweezer, Multimeter
General Items used mostly in all Electronic work :-
Flexible wire, Soldering Paste, Solder, P.C.B, Switch
Power Supply :-
Generally all electronic items work on low DC Voltage from 1.5 to 12 Volt so correct power source will be required. For exhibition purpose or low power project you can use pencil battery (AA Size) with battery container for connection. You can also use single 9V battery with snap depending on your circuit. For multipurpose use or for your own experiment purpose, battery eliminator will be good choice.
You will need electronic components based on circuit diagram : Identify circuit Symbols and buy components by its mention value. Example 100 K Resistance, BC548 Transistor etc.
You will need MP3 Kit.
Kit include MP3 Card with Digital Display, USB port, Remote Control and connecting cables as shown in the fig below :
You will need IR (Infra Red) Sensor which is commonly used in TV, DVD Player etc.
You will need Power Supply Source of 5V. You can use Voltage Regulator IC7805 if source voltage is greater then 6 Volt.
Power Supply Source can be 4Pcs chargeable Pencil Battery for portable use or for mains 230V Supply you have to use a 9V Transformer with rectifier circuit also known as adapter plus a Regulator IC 7805 as shown in the fig below.
You can also use SMPS type adapter of 5 Volt 1A. which is commonly available for mini cd Player or ipod charger. In that case you don’t need to use Regulator IC.
Half Amp current is enough if you are not using an Amplifier Circuit.
If you wish to use Speaker then you have to use Amplifier Circuit.
For Amplification you can use 6283 Circuit.
For Simple Circuit new Project we have omitted panel button which is marked K1,K2,K3 and K4 on PCB. All function is included in remote.
Circuit Diagram of this project will be available soon.
6283 Amplifier Circuit will be available soon.
Circuit Diagram of low cost refrigerator will be available soon.
