We have previously built 3x3x3 LED Cube using Arduino and Raspberry Pi. 3x3x3 LED Cube is generally build using some microcontroller, but in this session we are going to make a 3*3*3 LED CUBE without any microcontroller. Here we will use 555 timer IC and CD4020 binary counter setup to control the LED Cube.
Normally for controlling an LED CUBE, we…
If you are an electronics hobbyist then you must have heard about the 555 timer IC and its 3 popular circuits viz. astable multivibrator, bistable multivibrator, and monostable multivibrator. Apart from these, there are other popular circuits like 555 timer IC as a switch and police hooter that we have talked about previously. Adding to the list,…
The TDA7294 IC is a popular sound amplifier IC with low cost that has a ton of power handling capacity, 100W to be exact. For this tutorial, we are going to use two of those TDA7294 ICs in a bridge configuration to build an even more powerful amp that can handle up to 170W of RMS power. Throughout this tutorial we will walk you through the…
Today, our desks are full of devices that require connection to be connected with the PC via USB, or we need to work with multiple devices that have USB ports. It became a problem as Laptops lack multiple ports, and this is where a USB hub or USB Port Extender comes in handy. This comprehensive guide demonstrates how to build a professional DIY USB hub with a power supply using…
Raspberry Pi-based systems require internet connectivity to work at full potential, this is especially true for applications like IoT, image processing, remote sensing, and other cloud-based applications. Consider the case below: You need humidity sensor data in an agricultural field 200 meters away from your control unit, but there is no internet access or a power outlet in…
Arduino has always helped to build projects easily and make them look more attractive. Programming an LCD screen with touch screen option might sound as a complicated task, but the Arduino libraries and shields had made it really easy. In this project we will use a 2.4” Arduino TFT LCD screen to build our own Arduino Touch Screen calculator that could perform all basic…
Nowadays, Security system is one of the most researched fields and with increasing security threats, companies are launching new smart security products to combat these threats. IoT is an added advantage in this field which can automatically trigger an event, like calling the police, fire brigade or your neighbor, in case of any emergency. We previously built many security…
When soldering, sometimes the need arises to control the temperature of the soldering iron, especially, for micro soldering or any other precision soldering job. It is important to keep the temperature under control because overheating may damage sensitive semiconductor parts. That is where a temperature-controlled soldering station comes to play. But the problem is…
Audio content has come a long way over the past decades, from a classic tube amp to modern-day media players, technological advancements have changed the way digital media is consumed. Among all these innovations, portable media players have become one of the first choices among consumers, because of their vibrant sound quality and long battery life. So how does it work, and…
We have built several ESP32 projects using different ESP32 development boards. But these boards come with a power-saving mode called deep-sleep mode. Let's try to understand deep sleep on the ESP32 with an example. Take an example of a laptop. When it's in use, the fans spin at high speed, the display is on, some apps run in the background, and the battery drains fast. But when we close the…
An oscilloscope is the one instrument every electronics engineer reaches for when a circuit misbehaves. A multimeter tells you a single number, but an oscilloscope shows how a voltage changes over time: the shape of a PWM signal, the bounce of a switch, or the ripple on a sensor output. Bench oscilloscopes are expensive, though, and the best way to understand how one…
The SemLab Contactless Liquid Level Sense Module is an open-source, liquid level sensor designed for non-invasive fluid detection. By utilising capacitive sensing, the sensor detects the presence of liquid inside a container or pipeline without making direct contact with the fluid. This non-contact design prevents sensor corrosion, contamination, and degradation…
