Practical Tips and Techniques
The element browser in the Do-More Designer software will display valid memory locations, add documentation, and show how to cast from one memory type to another. We will be discussing the element browser and how to take advantage of this in your Do-More program. Let’s get started.
If you want to install a USB to RS485 adapter on your computer, you’ve come to the right place. We will use the CH340/341 USB to Serial port, an adapter that translates USB data into RS-485 communication. There is no need for an external power source or a head-scratching setup. It’s as easy as insertion, … Read more
The ultrasonic sensor (HC-SR04) is great for all kinds of projects that need distance measurements. The HC-SR04 is inexpensive and easy to use. We will be sending signals directly to the sensor and interpreting the results without the need for a library. Ultrasonic sensor module HC-SR04 provides a 2cm-400cm non-contact measurement function, the accuracy can … Read more
We will now be looking at how to use analog inputs to our Arduino UNO controller. An analog input converts a voltage level into a digital value. This can then be used in our Arduino program or sketch. The analog input signal can represent many different items. Speed, levels, distance, brightness, density, humidity, etc. are … Read more
We will now install software to program our arduino uno. This arduino uno software is a free download and will operate on several operating systems. The IDE (Integrated Development Environment) software uses a streamlined version of C++ to write and upload code to the boards. This software is open-sourced and available free of charge. It … Read more
I have recently come across a free virtual plc simulator called PLC Fiddle. It will enable you to create simple PLC ladder logic code within your browser free. This is an ideal way in understanding PLC concepts for industrial automation. All of the basic PLC instructions that come with most plc units have been incorporated … Read more
