The Raspberry Pi Zero W is the new and improved upgrade of Raspberry Pi Zero family. In this getting started series for Raspberry Pi Zero W, we have previously controlled an LED with Pi GPIO, interfaced a 3.5-inch TFT display with Raspberry Pi Zero W and in this tutorial, we are going to interface I2C 16x2 LCD and 4x4 keyboard with Raspberry Pi zero W. Throughout…

Hello electronics makers, this tutorial is going to be very exciting for you because at the end of this tutorial you will be able to program a new super low-cost microcontroller. I am always being curious to try new kinds of development boards and microcontrollers. If you are a regular reader of our website, then you might have seen our previous tutorial series on the…

Forest fires are common hazards in forests that cause a lot of harm to Wildlife as well as the Environment. It could be avoided if a robust system could be deployed in forest areas to detect the fire and alert to Fire extinguishing authority to take immediate action. In this project, the intention is to build a Forest fire detection system using IoT which would detect the…

We are here with yet another tutorial of the Raspberry Pi Pico. If you are following our Raspberry Pi Pico tutorial series, then you already know the basic setup and how to interface an OLED display module with the Raspberry Pi Pico. In this tutorial, we will use the Pico board to perform an ADC conversion. The Raspberry Pi Pico has four 12-bit ADC channels, but one of them…

Raspberry Pi zero W is an affordable and compact derivative of Raspberry Pi but if you attach Raspberry Pi zero W with monitor, keyboard, and mouse, it takes up a lot more space. There's no need to connect Reaspberry Pi to a display or input devices if you're only trying to program it or using it to operate electronics like lights, motors, and…

If you are following our Raspberry Pi Pico tutorial series, then you must have read the tutorial on how to interface an OLED display module with a pico board in which we measured the ADC value from the ADC channel of the pico board. In this tutorial, we will interface an ultrasonic sensor with the pico board and we are going to measure the…

In this article, we will make a buck converter using 555 timer IC and a IRFZ44N N channel MOSFET and use it as LED dimmer circuit or as a motor speed controller circuit. This circuit is basically a simple power electronics DC-DC Buck converter which can be used to step down voltage, its efficiency results in better battery life due to reduced heat generation making it a…

Many Analog Electronic circuits require dual power supply rails for proper balanced operation one being the Operational amplifier circuit. Negative supply voltage is also required in digital systems like A/D converters, op-amps, and comparators. In our previous tutorial, we built a +12V and -12V Dual Power Supply Circuit and a +5V and -5V Dual Power Supply Circuit but the…

In this tutorial, we will learn about the implementation of the Serial Parallel Interface (SPI) Communication on the STM8S103F3P6 board using an 8x8 Led matrix display module as the SPI device. There are 4 GPIO pins that we will be using to perform the SPI communication as shown in the image below. So, let…

If you are the one interested in working on some kind of smart home project but don’t know where to start and which smart home platform to use, this article might be of help. Previously, we have covered many smart home projects with different platforms and in this article, we are going to discuss about what Tasmota is, how does it work and…

Microcontrollers have small internal memory which is not enough to save sensors generated data for long time, either you have to use some external memory device or can save the data on some cloud using internet. Also, sometime it becomes difficult to manage when the sensor is deployed in some extreme condition site where human cannot reach or it is difficult to visit there…
