Digital Input With a Pushbutton With Arduino in Tinkercad

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 …

Latching power switch uses momentary-action pushbutton

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 …
