This is partially me sharing this technique, and partially me learning how to use Instructables. If there are issues with my documentation of the technique or my use of Instructables, please let me know in the comments – thanks! I needed a long row of switches in a pinch, and didn’t have nearly enough switches […]

This might seem totally useless, considering how advance current technology can be and you might even be like “Tsk! a Thermometer?” But there is a lot of experiment based on temperature (water temperature, room temperature, etc) so digital thermometer becomes a key instrument for temperature measurement considering the other alternatives and cost/performance ratio. It is

Please subscribe to my YouTube channel. In this tutorial we will hack our old school digital watch which is no longer working now. So let’s fix the watch Control it’s LCD display which is known as D-type LCD display. Step 1: Open the Watch Take the old school broken digital watch open the screws from behind. look
Hello to everyone, today I am here to show you a very insteresting project that I was working on for a while, it consists on a digital scale using the ESP-12S microcontroller plus a load cell and it HX711 wheatstone bridge to i2c converter, it is capable to measure weight precisely in the spectrum of

In this project we will have a closer look at accelerometer ICs and find out how we can use them with an Arduino. Afterwards we will combine such an IC with a couple of complementary components and a 3D printed enclosure in order to create a digital spirit level. Let’s get started! Step 1: Watch the

Digital design refers to creating digital circuits. Digital circuits are in basically everything today and range from something as simple as a circuit that turns an LED on when a button is pressed to the complex processor in the device you are reading this on. Traditionally, these circuits are built by making ASICs (Application Specific Integrated Circuits) out

I found on Ebay very nice, small 12v 23A battery holders for PCB mounting style and decided to fit the SMALL DIGITAL BAROMETRIC ALTIMETER just on the back of the holder. So basically this is the same schematic as the SMALL DIGITAL BAROMETRIC ALTIMETER, however I moved some of the connections to different MCU pins because of PCB

Testing of digital electronic systems generally involves applying a set of test stimuli to inputs of the device-under-test (DUT) and analyzing responses of the system using a response analyzer. If the DUT generates correct output responses (also called the golden response) for all the input stimuli, the DUT is regarded as fault-free. Those DUTs that

LCDs are widely used in applications like token-display machines in smalls and supermarkets, order number displays in restaurants and café, and so on. The project presented here demonstrates the working of Arduino based message display on LCD using Bluetooth. Circuit and working This circuit uses Arduino board that accepts data via HC-05 Bluetooth module from

A digital soil moisture meter is used for indicating the water content of a given soil sample. As crop production requires water at different stages and in different amounts, it is important to measure soil moisture from time to time to know its status. The digital soil moisture meter circuit presented here, for monitoring the
