Arduino based project in charge of taking care of your green plant. Particle Core based project in charge of taking care of my green plants. The water pump will not work with a voltage under 5V. In order to power it, I soldered a wire straight on the VUSB pin of the USB header. The […]
How to Interface Flux Sensor
https://www.electronics-lab.com/interface-flux-sensor/
This tutorial is going to teach you the basics on using Flux Sensor: It is a flex sensor which is 2.2 inches in length. This sensor works by bending the sensor itself. As the sensor is being flexed or bent, the resistance across the sensor increases. The greater the angle of bending, the greater the […]

How to Scroll a single LCD line – Arduino
https://www.electronics-lab.com/scroll-single-lcd-line/
R Jordan Kreindler show us how to scroll a single line on a LCD display. The Liquid Crystal Library has two quite useful functions scrollDisplayLeft() and scrollDisplayRight(). These functions scroll the whole display. That is, they scroll both lines on a 1602 LCD and all four lines on a 2004 LCD. What we often need […]
