![]() ![]() ![]() Some strong cutters (to make cutouts on you enclosure).A Single Layer PCB (because I home etched mine for this as it reduces unwanted signals and noises in the circuit and being it a testing circuit etching your own PCB is advised for getting accurate results).1x Enclosure Case (I used a plastic Switch Board Enclosure Case/ Plastic Project Box).3x Banana Jack Connector Cable (with Male Heads).2x 4 Pin Polarized Header Cable - Relimate Connectors.3x 3 Pin Polarized Header Cable - Relimate Connectors.1x 16 Pin Polarized Header Cable - Relimate Connectors.1x Red LED (you can use any colour I chose Red as it it used to denote POWER).1x Rotary Encoder w/ Button Module and KNOB.2x 10k ohm preset (Variable Resistance).I made another one for you guys with 5% tolerance resistors and changes the value of resistors in code and that worked too :) Just buy 5-7 resistors of 5% tolerances and find out 3 resistors having same value on the multimeter. UPDATE: For those who are having problems in finding 0.1% or 1% tolerances. 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. 3x 470k ohm Resistor with 0.1% Tolerance (1% Tolerance would also do).3x 680 ohm Resistor with 0.1% Tolerance (1% Tolerance would also do).1x LM336 - 2.5V Voltage Reference Diode.2x 1N5819 or any other Schottky Diode with current rating of 1A.With some basic components and tools you will be ready to build.!! Let's Start the build and you'll explore much more on the way to build your own.!! the maker and developer of Component Tester and Karl-Heinz who developed the firmware for it. No, don't thank me for such wonderful thing thank MARKUS F. isn't that great :DĪnd yeah one thing i forgot to tell you guys it doesn't only detect the components it displays their respective values and properties too !! 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. Capacitors along with their Equivalent Circuit Resistance Value (ESR) So, here's what our Component Tester can test -Ģ. Yes, the same microcontroller which an arduino uno uses.!! Now what if I tell you that you can have one and that too made by yourself under INR 600 only (USD 10).Ĭoming 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 !! ![]() Being an Electronics student or hobbyist, you may have thought of getting a tester that could test almost anything "THE ELECTRONICS COMPONENTS, OBVIOUSLY!!" ![]()
