Raise you’re hand if you’ve ever soldered directly to a battery even though you know better. We’ve all been there. Sometimes we get away with it when we have a small pack and don’t care about longevity. But when [Robert Dunn] needed to build a battery pack out of about 120 Lithium Ion cells, he […]
This timer is useful in both domestic and industrial applications. It is a countdown timer programmable in the range of 1s …. 9999s. During this time, the load is powered by a relay on the board. For repeated timings, it is possible to memorize the timing duration (MEM LED on). The end of the period
Ceramic printed circuit boards (PCBs) are constructed of extremely high thermal conductivity elements such as alumina, aluminum nitride, and beryllium oxide. They can swiftly transfer heat away from hot spots and disperse it across the entire surfaces. Today, I will share more about What is Ceramic PCB and why you should go for it. Let’s
The design was inspired by a product that is also presented on Instructable called “Arduino Basics with Night Light” (https://www.instructables.com/Arduino-Basics-With-…). Originally, the device is only allowed to change the LED lights by pushing down a button; after adding the codes and circuits (added: a speaker to notify the user for using recommended relatively peaceful color-blue/a

In a previous project we created an interactive coffee table, which lit up leds under an object. In this project, we reuse that table to create a snake game from the 2D matrix of LEDs. If some parts of the project are unclear, it may be addressed in the previous project, so I recommend reviewing that
Like many of us, [quincy] feels the distracting pull of non-work programs on what has become a mixed-use computer. So what’s the answer to the puzzle of work-life balance? We’re not sure, but time management and keeping track of tasks will probably get you most of the way there. The only problem is that keeping

Let’s learn how to blink an LED (light emitting diode) using Arduino’s digital output. If you’re new to Arduino, this is a great place to start. We’ll connect an LED to the Arduino Uno and compose a simple program to turn the LED on and off. You can follow along virtually using Tinkercad Circuits. You can
The ESP32 has about 4MB of internal flash memory and since the data stored within the flash memory is retained even when power is recycled, it becomes super useful for applications where you need to keep certain amount of data even after power off. For today’s tutorial, we will learn how to read and write

The DPS5020 is a constant voltage/current programmable control power supply module, that integrates analog and digital control in one device. Th e module is a 0-50V/0-20A Lab PSU module that comes in 2 parts, the main controller and a front panel. The main board has connections for input/output voltage as well as connection headers for Bluetooth and USB to

The Joker is a popular character in the Batman franchise, and at times uses poisonous gases as part of his criminal repertoire. That inspired this fun project by [kutluhan_aktar], which aims to monitor the level of harmful gases in the air. The project doesn’t use just one gas sensor, but several! It packs the MQ-2, MQ-3, MQ-4, MQ-6,
