Mistakes That Not to Make As an Arduino Beginner

Arduino is an open-source hardware and software company that designs and manufactures single-board microcontrollers and micro control kits for building digital devices and interactive objects that can sense and control objects in the physical and digital world.

There are several mistakes that a beginner makes, they include;


It tends to pull more power from the Arduino, which might lead to ruining of your microcontroller. Avoid the rush and read the instruction till you understand the steps involved. Also, motors are not advised to use directly with the pins as they also drain the power. It is highly advised to use an H-bridge motor. They allow control of DC powered motor without damaging your Arduino.


It occurs when Arduino pins are connected to wrong places. It causes power currents to flow in unintended places thus causing short-circuiting. To avoid such occurrences, it’s better to read the manual thoroughly and understand it. You should familiarise yourself with the rail working. For example, the outer rails work horizontally and the inner rails vertically. Always give it a last thought before powering your device as you might identify are the wrong connection and change it.

Microcontrollers working is all about pins. They are supposed to be attached to a protoboard. Mixing of Gate, drain and source might lead to power mislead which latter affect your Arduino appliance understanding the importance of each pin is advantageous as there is no way you will ever connect the pins wrongly causing them to backfire on you.


Typical errors such as the wrong placing of the lower/upper case or semicolons are what most beginners experience. They tend to alter your program thus not working normally. To avoid this reference from another program as you type as all programs are the same.

Pin voltage causes an unstable reading of information from the Arduino Nano. When trying to reference something from your Arduino, it might lead to unwanted happenings which are brought about by other unwanted devices close to your Arduino nano. To avoid this ensure the voltage pin is not reducing.


Beginners mostly tend to confuse the V+ and the GND pin. If you want to power your Arduino the V+that is connected to the VIN pin, while the Ground wire goes to the GND pin. If one confuses the two, then you are likely to affect your device. Kindly check your power setup before turning it on.

The serial enables one to display data from the Arduino pins. Problem faced at this point is trying to set up a microcontroller to display at the serial monitor and being at the disappointed at the end. Luckily there is an easy way out, when loading the serial monitor you should also set its baud rate using a drop-down menu at the serial monitor bottom too.
