Arduino Opta PLC Pros & Cons

The continuous COVID-19 pandemic has caused economies around the world to experience financial hardship. Industries have been impacted as a result, and businesses have been pressured to adopt new technology and processes to stay competitive during these tough times. There has been increasing discussion in the automation sector about whether Arduino can replace PLC in order to develop a first programme and support businesses through the economic downturn. In this essay, we’ll examine Arduino’s potential as a PLC replacement and how it may help organisations in the present business environment.

Unlocking the Potential of PLC

PLCs are a type of gadget used in automation to manage and watch over industrial processes. It is extensively utilised in manufacturing, packing, and other sectors where exact machinery control is necessary. PLCs are made to perform reliably in challenging industrial environments for lengthy periods of time. They have the ability to manage alarms, monitor sensors, and regulate motors, among other things.

Contrarily, Arduino is a free and open-source hardware and software platform for creating electronic projects. It is a well-liked tool for making electronic prototypes among DIY enthusiasts and amateurs. Arduino boards are a great choice for novices who are just beginning to learn about electronics because they are inexpensive and simple to use. However, some industry professionals contend that Arduino can potentially be utilised as a PLC substitute.

The Incredible Impact of Arduino as a PLC

Cost-effectiveness is one of the key benefits of utilising Arduino as a PLC substitute. PLCs can be very expensive, both initially and in terms of upkeep. On the contrary hand, Arduino boards are reasonably priced and provide features that PLCs do. For small and medium-sized enterprises that do not have the funds to invest in pricey automation technology, this profitability can be extremely helpful.

Flexibility is another benefit of adopting Arduino as a PLC substitute. PLCs are made to carry out particular duties, whereas Arduino can be configured to carry out a variety of jobs. Due to its adaptability, Arduino is a more flexible alternative that enables companies to tailor their automation systems to suit their particular requirements. For companies that need specialised automation equipment, this can be extremely advantageous.

Uncovering the Limitations of Arduino

However, utilising Arduino as a PLC substitute has several drawbacks. The biggest disadvantage is reliability. Although Arduino boards are dependable for DIY and educational projects, they might not be appropriate for commercial applications that need to run continuously. Unlike Arduino boards, which may eventually face reliability problems, PLCs are made to function reliably for extended periods of time. Additionally, whereas Arduino boards might not be as tough, PLCs are frequently built to survive harsh industrial settings.

Despite these drawbacks, numerous companies have used Arduino as a PLC substitute with success. Installing the Arduino software and connecting your board to your computer are prerequisites for writing your first programme with the Arduino platform. Then, using the C++-based Arduino programming language, you must write your code. Your automation system can be operational after the programme has uploaded the code to the board.


To sum up, in order for firms to stay competitive, the protracted recession has compelled them to adopt new technology and processes. Although PLCs are frequently used in automation, they can be costly and may not be appropriate for all types of enterprises. Contrarily, Arduino provides a flexible and affordable alternative to PLCs, making it a great choice for companies that need specialised automation technology. Despite the fact that PLCs may be more reliable, numerous firms have used Arduino with success in their automation systems. Installing the software, writing your code, and uploading it to your board are all steps in the Arduino programming process. For companies wanting to survive, Arduino can be a fantastic alternative with the correct programming knowledge and skills.
