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
you can also detect the IR Codes by simply putting a TSOP Sensor on its test pins.... isn't that great
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 !!https://www.instructables.com/id/Component-Tester-Test-Almost-Anything-/
