Practical Tips and Techniques
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
Node-RED can easily log data to a database. SQL (Structured Query Language) can be used to communicate to a SQL database. Databases separate analysis from the data unlike spreadsheets like Excel. The database is designed to hold more information than spreadsheets and allow multiple users to access the information. We will be creating an SQLite … Read more
The servomotor, RC (Hobby) Servo is a type of gear motor that can only rotate 180 degrees. It is controlled by sending electrical pulses from our UNO R3 board. These pulses tell the servo what position it should move to. We will be wiring the servo to our Arduino UNO R3 controller on our super … Read more
We will now establish communication using four different methods from our computer to the new Click Plus controller. The click programming software version 3.00 will be used for the communication methods. Click Plus controllers allow you to program them through the micro USB port on every CPU. WiFi (Bluetooth Provisioning) is also available on some … Read more
Node-RED can easily display interactive information to the user or operator using a web browser on your phone, tablet, or computer. Any device that has access to the network in which node-red is running. We will be installing the node-red-dashboard palette. This allows us to create a live data dashboard user interface. (UI) The information … Read more
We will now look at the tilt ball switch on our Arduino Uno super starter kit. Tilt sensors (tilt ball switch) allow you to detect orientation or inclination. They are small, inexpensive, low-power, and easy to use. Their simplicity makes them popular for toys, gadgets, and appliances. Tilt ball switches are sometimes referred to as … Read more
