Arduino Components Tester

Hello friends...!

You can make your own COMPONENT TESTER.

It can test....

Resisters

capacitors

Inductors

Every type of transistors(BJTs,MOSFETs,IGBTs..etc...)

And many things

It not just a component tester,but also it is a PWM generator........

Step 1: Components You Need.

List:-

Electronics.......

Arduino nano - 1

16*2 LCD - 1

9v Battery - 1

9v Battery cap - 1

PCBs

Resistors ---

680R - 3

470K - 3

1K - 1

variable resistor 10K - 1

some wires

push switch - 1

on/off switch - 1

equipments

soldering station or soldering iron,cutter etc...

Step 2: Diagram of Tester

R1 - 470K

R2 - 680R

R3 - 470K

R4 - 680R

R5 - 470K

R6 - 680R

R7 - 1K

RV1 - 10K

C1 - 100nF

Step 3: Connect Everything As Per Circuit Diagram

Codes you have to need is here

Step 4: Case for It

here i make case using PCBs

cut the pcb in size of main circuit

and cut some part of top pcb for LCD.

Assemble case using silver-copper wire...

simple.... ; )

Step 5: Some Test

Now it ready to be use.

Some tests you can show

Just connect the component to the probe and push the button.

If you want to use PWM function just long press the push button.

It's done.................
