Let’s learn how to read a pushbutton using Arduino’s digital input! We’ll connect up a simple circuit using a solderless breadboard and use some simple Arduino code to control a single LED. So far you’ve learned to control LEDs with code, which is one use for Arduino’s outputs. This lesson builds on outputs by adding an […]

For many people, the biggest change of 2020 has been adjusting to a glut of online teleconferences as a part of daily working life. [p_leriche] has had to adjust the way church services are conducted, and found managing a complicated streaming meeting setup to be complicated at best. To ease the workload on the presenter, he

How many mundane devices upgrade to IoT because they let you monitor a single data point or a variable? That little nudge over the communication precipice allows you to charge 500% more. Now, if you are as handy as a Hackaday reader, you can throw a lazy afternoon at the problem and get the same

Most inexpensive pushbutton switches, particularly pc-board-mounting and membrane types, have momentary action. Latching types are often larger and relatively expensive, and they frequently are unavailable in the style you’d like to use. You can thus have a problem if you need a small, inexpensive on/off switch for latching power to a load. The circuit in

This a door lock built as fun project. It is quite easy to build and a fun way to learn and improve your knowledge of Arduino. I tried to add a 16*2 display but there weren’t enough GPIO pins on Arduino Uno. If You are interested in adding a display you would need an Arduino
