Arduino boards and many affordable microcontrollers have emerged and changed pastime electronics significantly. What was once the field of the extensively knowledgeable in electronics and programming, is now available to all. However, starting out as a beginner can be quite challenging for people without an electronics background. Errors are encountered, some of which may have modest resolutions but might prove tiring to resolve. Below is an illustration of some common mistakes encountered and the solutions available when handling Arduino nano.
Externally Powering the Board in reverse
when running the board from a battery or power supply it is important to make sure that V+ is connected to the VIN pin, and the Ground wire to the GND pin. If this is done in reverse, the board gets fried. This clear error happens more frequently than expected, so constantly check the power setup before switching on anything. When the Arduino gets fried, more common than not this is the causative reason. The second most probable is because of drawing too much current from the board. Understanding the comparison between power consumption need of your device to how much the board can provide is crucial.
Running Devices Directly from Pins
It is conceivable to use some low powered components right with the Arduino nano pins. In many cases, too much power can be drawn from the Arduino nano, risking destroying the microcontroller. The vilest offenders here are motors. Even low power motors can draw a speckled rate of power and are typically unsafe to use with the Arduino nano pins directly. when using a motor, an H-bridge is used instead. These chips give access to control a DC powered motor using the Arduino nano pins, without endangering the board. The small chips dispersed the power supply from the Arduino nano allowing the motor to move in both directions. The easiest way to use these chips is as part of a safeguard for the Arduino Nano. They are available for purchase or can be assembled locally.
A common fault initially is managing to cause short circuits. These occur when parts of the circuit are joined in the wrong places, giving the power a modest path to follow. To evade this when using a breadboard, it is significant to comprehend how a breadboard works.
The same problem can ensue when soldering arduinos or devices to the protoboard, exclusively with smaller boards like the Arduino Nano. A small spot of solder between two pins can source a short which could break down the microcontroller. The only way to evade this is to be alert and practice soldering more frequently.
In conclusion, i is important to understand the mistakes made by most Arduino beginners make. An understanding of the solutions available provides you with insight and avoids future occurrence of the mistakes.
