Practical Tips and Techniques
The DHT11 is a digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and sends out a digital signal on the data pin (no analog input pins needed). Its simple to use, and the update timing of the sensor is about 2 seconds. Thermistor temperature … 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
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 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
We will now look at active and passive buzzer outputs on our Arduino UNO controller. Electronic buzzers are DC-powered and equipped with an integrated circuit. They are widely used in computers, printers, photocopiers, alarms, electronic toys, automotive electronic devices, telephones, timers, and other electronic products for voice devices. Buzzers can be categorized as active and … 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 be looking at using digital inputs (pushbuttons) to turn LEDs on and off. This will be programmed using our Arduino Uno R3 from our Super Starter Kit. Pushbuttons will allow actions to be performed that our Arduino program sketch will interpret and take action. We will be wiring two pushbutton switches. A … Read more
We will now look at creating BRX Do-More dynamic web pages on our PLC web server. These pages are great for operator information display. A dynamic web page is a web page that displays different content each time it’s viewed. For example, the page may change with the time of day, the user that accesses … Read more
We will now be looking at LEDs that we can wire and program using our Arduino Uno super starter kit. Light-emitting diodes (LEDs) are semiconductor devices that will show light when current passes through them. This light is produced within the solid semiconductor material so it can be called a solid-state lighting device. We will … Read more
We will now look at the BRX Do-More PLC Web Server. Ethernet equipped BRX CPUs and the Do-More Designer Simulator can now have a web server. This can be accessed by any web browser using the IP address of the BRX Do-More CPU. A web server is server software or hardware dedicated to running this … Read more
