Introduction: Arduino Multimeter and Components Tester
Hello, this is a mine multyfunctional Arduino device. It can be used to test sensors that are connected to analog pins, to measure resistance, to measure the voltage drop of the diode. It can measure ambient temperature, it has built in continuity test, pwm generator and much more.
Check this video to see demonstration of device:
Step 1: Parts Needed
You will need:
- Arduino nano
- oled screen 128x32 or 128x64 . Displan need to be I2C
- pcb
- 2k resistor
- some female headers
- buzzer
Step 2: Connecting Parts
Check the image in this step and connect your parts.
Step 3: Libraries
You will need download andinstall Adafruit library for oled.
Download it here
https://github.com/adafruit/Adafruit_SSD1306
Step 4: Programing Arduino Nano
download this code and upload it to arduino using Arduino IDE.

Does anyone have this running correctly ? Since the info page is down ! I have wired as per the original version but using the newer sketch - I need the new wiring diagram ! my 128x64 display is not displaying correctly (except for Analog read screen) the rest is stretched or missing half ! where do the mystery 10K and 100K resistors go? and seems only the middle button is working out of 3 ! They are connected to D2,D3,D4 or have they been moved in newer version ?

Hey - Probably too late but I just made this and I am having the same compile errors - How did you manage to fix this ?

Copy the sketch to a new tab without saving and then compile(worked for me).It was written in and old arduino version thats why.

Can someone can share some info how to make it work as same as in the video in the code given? Such as RTC and Temperature sensor. It's worth it to know about this. Thanks.

I agree with tutdude98. Great idea but limited information provided. For example there's no temperature sensor in the instructions but it shows up in the video.

Great idea, but you should really add more steps and details, this idea is really worth it to explain it a bit more
