Smart Irrigation System

During the summer, gardens abound — so many people are keeping an eye out for their sun-ripened, home-grown tomatoes or for that lovely hydrangea that’s just the right shade of blue. But summers are also a very hectic time. So how do you maintain that garden and make sure it receives the care it needs? One of the projects created for the Digilent Design Contest 2015 is a smart irrigation system intended to work with an Android device to see to it your garden gets the moisture it craves.

Debouncing Circuits

Pushbuttons are an inherent source of problems inside of sensitive circuits. Ideally, we like to think that when a button is pressed it is either “pressed” or “not pressed” without any sort of funny business. Unfortunately, as pushbuttons are a mechanical component, a lack of funny business simply isn’t going to be the case.

Getting Started with Xilinx Vivado and the Nexys 4

We’ve posted plenty of projects before that make use of Vivado. But how do you begin using it? This Instructable provides a guide to getting started with using Xilinx’s Vivado CAD with the Digilent Nexys 4. Alex uses Verilog to create the logic design. The Digilent Intro to Verilog Project provides an introduction to logic design.

I2C in LabVIEW

I recently published an Instructable on how to use I2C in LabVIEW using LabVIEW MakerHub LINX, chipKIT WF32, and PmodGYRO as an example. Digilent sells a both LabVIEW Home Bundle and chipKIT WF32 in the LabVIEW Physical Computing Kit. In this Instructable, I go over how to read the data sheet to find what you’re looking for and how exactly to code what you find. This guide also details how to set up pull-up resistors for successful I2C communication.

Color/Colour Invaders!

I was recently inspired to try out by Hamster’s own ​Colour Invaders project. As the name suggests, this project is similar in design to the classic Space Invaders game or (more similarly) the ​Casio’s Number Invaders on the calculator. The idea behind the game is that different colored “invaders” start marching down the LED strip and you have to fire missiles that match the color of the oncoming invader. Naturally, as you successfully destroy more of the attackers, the faster they come towards your base. Here is what you need to get started.
