Everyone knows Arduino is a powerful programmable controller that helps make things happen, but testing its circuits can be confusing — especially when there are many options available. Before buying any Arduino you must know how it works, how to make and test it, and which is the best multimeter for Arduino circuits testing?
What is an Arduino?
An Arduino is an open-source microcontroller board, which can be programmed to control various electronic devices. You can program it through its compatible free software. There are many online communities where you can put your queries or answer other people’s issues. Moreover, these Arduino boards are equally famous among colleges and industry projects. Although their types may vary depending on user requirements.
Types of Arduino
Choosing the right Arduino board for the right job is also important. Let's suppose you want to make a robotic car then you can do it with just Arduino UNO R3. But, if you want to make a robotic arm or any other wireless project then AT Mega328 will suit you the most. Some of the most common types of Arduino are as follows;
The most common model of Arduino was released in 2010. It has six analog inputs and six digital outputs.
The second most common model of Arduino was released in 2012. It has 16 digital inputs and 16 digital outputs as well as six analog inputs and 12 digital outputs.
The newest model of Arduino was released in 2014. It comes with an Atmega328 chip that uses the 32-bit ARM architecture. It can be programmed using the C++ programming language or the Arduino IDE software for Windows, Mac OS, and Linux.
It is an Arduino-compatible microcontroller board based on the Atmel ATmega32U4 microcontroller. This board is manufactured by Leonardo da Vinci's followers, Fondazione Leonardo. It is intended for use with the Arduino bootloader, AVRDUDE, and the STK500 or STK3 development boards.
The Micro-Arduino is a compact Arduino Leonardo-compatible development board with a built-in USB connection and power regulator. The Micro-Arduino was designed for use in embedded systems and robotics. It comes with 1KB of flash memory, 256 bytes of RAM, and a full-size USB connector.

There is no grudge in saying that being an electronics engineer I am a Klein tools lover. The major reason for choosing the Klein multimeter is that they are highly safe as well as perfect for both electronics and electrical testing. Klein mm600 and mm700 almost look similar but are way different from each other in terms of features. I have also made a comparison between Klein mm600 vs mm700. Hopefully, that can answer all your questions. Coming back to the point Klein mm700 is a potential competitor of fluke 117. Although it’s almost half the price of a fluke in some cases it’s way better than a fluke multimeter. For an extensive look I am writing down sits specifications below.

You can also grab the best multimeter for Arduino testing from the above top 5 picks and let us know about your experience.
What are the necessary tools for Arduino testing?
You need a screwdriver set with insulated gloves and a good quality multimeter to test the Arduino circuit. In some cases, you might require some jumper wire. But I believe being an electronics technician they are already in your toolkit.
Arduino runs on which supply? AC Voltage or DC Voltage
Almost every electronic circuit runs on a DC power supplies. You can energize your Arduino module with a voltages range of 5v-12v. You can either use a 9v battery or a direct 5V-12v DC power supply to make an Arduino operational.
How to test an Arduino with a digital multimeter?
First of all, you must know about which type of Arduino board you're using and which purpose it serves. Arduino boards have analog and digital I/O pins. All of these pins have rated voltage range and current rating. You can see these details from the Pin configuration chart. Always make sure that you power up your board from a standard and noise-free power supply. The standard voltage range of android boards is 7-12VDC.
