DIY Electronics

Had some time this weekend and a desire to create something new and interesting, so went ahead and created an Arduino/NodeMCU based indoor dial thermometer. This device displays the temperature in degree centigrade on a D-Shaped Gauge as well as on a 7-Segment display. In addition to that, it also saves the temperature and humidity readings in a MySQL DataBase hosted on a home based Raspberry Pi Server. The data is then displayed using the "Our Smart Home" app.

Rechargeable Gothic Lantern ------ A Gothic Lantern is a captivating piece of lighting that brings the allure of the Victorian Era into your home. The lantern is adorned with ornate top and bottom ornaments, reminiscent of the Gothic style that was prevalent during the Victorian Era. My curiosity to create something new and interesting got me into this gothic style rechargeable lantern. The design is both nostalgic and timeless, making the Gothic Lantern a perfect fit for homes that cherish a touch of historical charm. Watch this video for detailed step by step instructions on how to build this lantern and for a complete instruction on how the electronic circuit works inside the lantern.

PCBway: only $5 for 10 pcbs from https://www.pcbway.com/?from=CZcouple The 555 timer IC is an integrated circuit (IC) that is used in a variety of timer, delay, pulse generator and oscillator circuits. In this tutorial, I am going to show you guys how to make an "Adjustable Delay Timer Circuit" using the 555 timer IC. This circuit can automatically turn on/off any circuit after a fixed duration. This timer circuit is useful when you need to power On/Off any AC Appliances after a pre-defined duration. For example, you can use this circuit to automatically turn off a mobile charger after a certain period of time to avoid over charging, or you can turn on/off a light bulb after a certain period. The time delay of this circuit can be adjusted by using various combinations of resistors and capacitors. Watch this video for detailed step by step instructions on how to build this circuit and to know how this circuit works. Thanks ------ Thanks again for checking my post. I hope it helps you.

Proximity sensing is a very common application in electronics. There are several ways to accomplish this. The most common way is by using a PIR sensor. PIR Sensor senses the change in ambient infrared radiation caused by warm bodies. I have already covered this in my Tutorial No. 5: "PIR Sensor Tutorial - With or Without Arduino". However, since PIR sensors detect movement from living objects, they can generate false alarms. These sensors are also inefficient in hot environments, as they rely on heat signatures. The other common methods of proximity sensing involve, using reflected ultrasonic or light beams. Using these sensors, the intruding object is detected by the reflected beam back to its source. The time delay between transmission and reception is measured to calculate the distance to the object. In this tutorial, we are going to look at another method of proximity sensing using "Microwaves" and "Doppler Effect". In my hand is an inexpensive RCWL-0516 Microwave Radar Motion Sensor. The RCWL-0516 microwave sensor detects "any movement" from "any object" and does not rely on heat, making it more reliable in hot environments. I am going to use this sensor to create a geo-fence around my house to detect motion and get notifications.

PCBway: only $5 for 10 pcbs from https://www.pcbway.com/?from=CZcouple Wanted to generate a LED fading effect (fade-in and fade-out) for my upcoming video tutorial using the 555 timer IC. I already have a video where I used LM358 Dual Operational Amplifier IC and another one with Arduino to generate the LED fading effect. YouTube, is full of video showing how to generate the fading effect using 555 timer IC. However, none of them produce a true fading effect. Some just fades-in but never fades-out. And there is literally no explanation of how they are generating the fading effect other than just showing how to assemble the components. In this tutorial, I am going to show you guys how to create a true LED fading effect using the 555 timer IC. I will also explain how the circuit works and how changing components change the fading effect of the LEDs. ----------------------------------- Thanks again for checking my post. I hope it helps you.
