Being an Electronics student or hobbyist, you may have thought of getting a tester that could test almost anything "THE ELECTRONICS COMPONENTS, OBVIOUSLY!!"
Now what if I tell you that you can have one and that too made by yourself under INR 600 only (USD 10).
Coming upon COMPONENT TESTER so it can test almost everything, obviously not the power components because they require more current and power which our AVR Microcontroller couldn't handle !! Oh yeah, I forgot to tell you guys that we would be using an ATMEGA328 for our build !!
Yes, the same microcontroller which an arduino uno uses...!!
So, here's what our Component Tester can test -
2. Capacitors along with their Equivalent Circuit Resistance Value (ESR)
no the list doesn't end here.... it can test Voltage upto 50V, it has a FREQUENCY COUNTER and a FREQUENCY GENERATOR TOO :D
you can also detect the IR Codes by simply putting a TSOP Sensor on its test pins.... isn't that great :D
and yeah one thing i forgot to tell you guys it doesn't only detect the components it displays their respective values and properties too !!
No, don't thank me for such wonderful thing thank MARKUS F. the maker and developer of Component Tester and Karl-Heinz who developed the firmware for it.
Let's Start the build and you'll explore much more on the way to build your own..!!
with some basic components and tools you will be ready to build...!!
NOTE: For 1% Tolerance and 5% Tolerance(not recommended but works with less accuracy) 680 ohm and 470k ohm resistors you need to make some changes in code and try to have all resistors indicating same value on multimeter.
UPDATE: For those who are having problems in finding 0.1% or 1% tolerances. You can use 5% tolerances. Just buy 5-7 resistors of 5% tolerances and find out 3 resistors having same value on the multimeter. I made another one for you guys with 5% tolerance resistors and changes the value of resistors in code and that worked too :)
Let's Start the build !!
