Our Verdict
This course stands out as a practical introduction to programming Arduino as a Modbus RS485 Master and Slave. Though sourcing the exact hardware can be challenging, the instructor's clear guidance on libraries and coding makes up for it. Enhancing theoretical foundations and incorporating more diverse examples would further strengthen this valuable resource.
What We Liked
- The course offers comprehensive coverage of programming an Arduino as a Modbus RS485 Master and Slave, ideal for those seeking hands-on experience.
- Instructor explains the libraries and walks you through coding with the Arduino IDE, making it easier to understand the process.
- Well-organized content helps learners grasp Modbus communication via RS485 cables, which is reinforced with practical examples.
- The course is excellent for both beginners and those with prior knowledge, providing thorough insights into Modbus registers and memory maps.
Potential Drawbacks
- Some users find it challenging to source the exact RS485 shield used in the course, causing potential confusion during hardware setup.
- A more extensive range of practical examples, particularly for slave devices, would enhance understanding and application.
- While there is some theory provided, a stronger foundation in Modbus basics could benefit those new to the topic.
- The course focuses on using specific hardware; it might be helpful to offer more widely-available alternatives for learners.
