Protection circuits are vital for any electronic design to be successful. In our previous protection circuit tutorials, we have designed many basic protection circuits that can be adapted into your circuit, namely, Over Voltage Protection, Short-Circuit Protection, Reverse polarity protection, etc. Adding to this list of circuits, in this article, we will learn how to design…
In previous tutorial we have discussed about MQTT Protocol and installed local MQTT server on our Raspberry Pi for controlling the GPIO locally. But the drawback of local MQTT server is that we cannot control the GPIOs from anywhere in the world, it only provides services locally. But if this MQTT server is hosted on some cloud then any appliances connected to Raspberry Pi…
Raspberry Pi is an ARM architecture processor based board designed for electronic engineers and hobbyists. The PI is one of most trusted project development platforms out there now. With higher processor speed and 1 GB RAM, the PI can be used for many high profile projects like Image processing and Internet of Things.
For doing any of high…
Automobiles have been the primary mode of transportation for most of us and we depend on them for our day to day commute. Unfortunately there are lots of mishaps that could occur while driving an automobile and Brake Failures are one such case. Of course accidents cannot be avoided sometimes but they can sure be prevented by taking some preventive measures. In this…
Recently I got intrigued with all the new Home Automation products in the market and hence I purchased a Google Home Mini and few other smart devices to control lights, fans, AC and what not. While it did work and everything was fun to use, I got a bit troubled with having all these wireless connectivities happening around me. My bedroom alone had 5 smart devices, and…
STM32 Microcontrollers which uses ARM Cortex M architecture is now becoming popular and are used in many applications because of its feature, cost and performance. We have programmed STM32F103C8 using the Arduino IDE in our previous tutorials. Programming STM32 with Arduino IDE is simple, as there are lots of libraries available for various sensors to perform any task, we…
In this project we are going to make a Heart Beat Detection and Monitoring System using Arduino that will detect the heart beat using the Pulse Sensor and will show the readings in BPM (Beats Per Minute) on the LCD connected to it. It will also send the readings to ThingSpeak server using the Wi-Fi module ESP8266, so that Heart Beats can be monitored from anywhere in the…
The name of the circuit itself infers the application. This circuit triggers the alarm if the door of Fridge is left open for the long time. When the door of the refrigerator is left open, the temperature inside the cabin will increase. This rise in temperature will be sensed by thermostat and try to cool down the cabin. It will always try to maintain constant temperature of…
In this age of IoT (Internet of Things) where everything can be controlled remotely using your smartphone, why to carry keys with you. There are lots of technologies to support wireless controlling of devices like RFID, Bluetooth, Wi-Fi, LoRa. We previously built some door alarms and door controlling circuit to open and close the door wirelessly:
Arduino RFID Door Lock…
Absence of light is what causes darkness, and we can automatically detect darkness or intensity of light using a Light Dependent Resistor (LDR). The circuit can be integrated with other electronics circuits or projects to control lights of a small bulb for automating lighting of something as large as whole city’s street lights. In this project, we will be making a…
Whether it’s your Laptop, TV, Smartphone, or any other electronic device, they all operates at different voltages. These devices have sensitive components like Microprocessors, ICs, etc. that works on very low voltage, and even the slightest change in voltage can damage these components. These sensitive components require a steady and stable voltage to operate optimally. So…
The aim of this project is to monitor a Lithium Battery Bank remotely in a solar installation. It traces current individually for each Battery Pack. It also communicates with solar charger and calculates live values of power going to home and battery bank. It includes a web server with charts, internal historical data, and optionally can also upload data to Thingspeak and…
