We have seen various applications of IoT but what about adding the touch to it. In this project, we will add simple touch buttons to the ESP-32 Wi-Fi module. ESP-32 is a great module to design IoT applications and adding touch to it will make it further smart. Talking about …

This article explains spectrogram of the speech signal (analysis and processing) with MATLAB to get its frequency-domain representation. In real life, we come across many signals that are variations of the form ƒ(t), where ‘t’ is independent variable ‘time’ in most cases. Temperature, pressure, pulse rate, etc can be plotted …

GPS tracker allows you to never lose track of anything by working out exactly where it is. Its an ultimate gadget to prevent a vehicle from being stolen, monitoring the route of a delivery vehicle over its journey, or even to monitor high-valued assets in transit. Modern trackers available on the …

Electronics projects are always in high demand. Students work on them to improve their skills, whereas hobbyists like the fun in meddling with technology. For professionals, it’s a different ball game altogether. Mini projects form a middle ground for all segments of electronics engineers looking to build. We compiled a …

In this DIY Project, I will show you how to design a simple Arduino based Door Monitoring system using Reed Switch. A Door Monitoring System is a simple application which continuously monitors the status of the Door i.e. whether it is opened or closed. Based on the status further actions …

This circuit is based on a thermistor and an operational amplifier (op-amp) that drives a MOSFET to switch a cooling fan on and off in an active heatsink system. The design also includes an overload protection mechanism. An active heatsink is normally included in electronic products such as power supplies …
