Today I will be making a simple all-in-one component tester device which can test any component like LEDs transistors mosfets capacitors Triax resistors and also other components instead of messing up the connections on prep board I first prepared the circuit diagram in cab then I converted schematics into the PCB layout and the PCB is going to be look like this you can download both circuit diagram and I cleaned the PCB with isopropyl alcohol and here our PCB is looking nice and clean now use 0.96 inch OLED display and connect it at its place you can use that Mega 3 to 8p chip with external Crystal but I preferred simply to use Arduino Nano for this project download this code link is in video description also make sure all these libraries are installed then click to upload the code foreign and yes use this button cap if available now with this device we can test all these components like and channel fed p-channel fet try out capacitors LEDs transistors and resistors I use mobile charger to provide firewall to this device and here our tester is ready to test different types of components as you can see the voltage forward of this led is 2.06 volts since this display is bi-color that's why second text line is appearing Little Broken it is recommended to use single color OLED display for this project you can also test the LEDs in reverse polarity it can automatically detect the pins for testing you can test any transistor and it can show whether it is npn or PNP and also it can show whether mosfet is in Channel or P Channel even you can test any type of triacs electrolyte capacitors can also be tested but make sure capacitor is discharged before testing you can also test any resistor and device can show necessary information foreign capacitors can be tested with the same device as you can see this tester is working great and shows the necessary information of each component if any component is not working or not connected it will show this error message you can also add these hookup wires to test the bigger components like this.
