All your life you thought having 100 somethings meant having this many: When, really, it only meant having this many: No, Rod Serling’s not about to cross into the frame, and you haven’t swallowed any red pills . You’ve entered the binary zone and have just encountered base numbering systems. Number Systems and Bases Number systems are the methods we use to represent numbers.

  IoT Power Relay  Introduction In this tutorial, we'll show you how to host a webpage on the ESP32 Thing that will allow you to set times for a power relay to be turned on or off. It utilizes our ESP32 Thing , IoT Power Relay , and the Qwiic Micro OLED screen to create a smart outlet that can maintain a weekly schedule for powering any AC powered load you want to cycle regularly. Required Materials Hardware To follow this project, you will need the following materials. Depending on what you have, you may not need everything on this list. Add it to your cart, read through the guide, and adjust the cart as necessary. Software You will need the Arduino IDE with the ESP32 software support package installed. In addition, you'll need to download the IoT_Power_Relay code from GitHub. Visit the links to access the installs and code as well as more information on installing board support for the ESP32 in Arduino. Hardware Hookup Bas...
