Arduino-Based MOSFET Terminal Identification System

Metal oxide semiconductor field effect transistor (MOSFET) is a semiconductor device widely used for switching applications and amplifying electronic signals. While the facility to determine the type and pin configuration of bipolar junction transistors (BJTs) are available in digital multimeters (DMMs) used in the laboratory, most DMMs do not provide such features for MOSFETs. This Arduino-based project al ...

Arduino Based Digital IC Tester Using MATLAB

Testing of digital electronic systems generally involves applying a set of test stimuli to inputs of the device-under-test (DUT) and analyzing responses of the system using a response analyzer. If the DUT generates correct output responses (also called the golden response) for all the input stimuli, the DUT is regarded as fault-free. Those DUTs that fail to meet the golden response are regarded as faulty or ...

Controlling A Linear Actuator With An Arduino

There is a wide application of linear actuator where one wants to move something but they do not want to physically get involved in moving it. There are quite a number of ways to control linear actuators depending on the application and the user experience required. These are the key aspects determining the setup and the way this setup will operate. It is common for most movements to involve manual control ...

Generic STM32 board with Arduino

Described here is a simple way to load a program without bootloader. An additional thing needed is a USB to Serial/UART/TTL adapter (3.3V level). Connect the USB to Serial board as follows, and power up the STM32 board from a USB port/power supply. • RXD – A9 • TXD – A10 • GND – GND I assume you have already installed the Arduino IDE. Next, you need to go to ‘Board Manager’ under ‘Tools’ and install the sup ...

Arduino as AVR Programmer

For my project I need two Arduino boards, but I have only one Arduino Mega 2560 board (refer Fig. 1). I can either buy an Arduino Uno board (that costs approx. Rs. 1400 in India) or I can make an Arduino board using a fresh ATmega328/ATmega328P chip. Suppose you have an Arduino board that is built on ATmega328P or ATMega8A-PU chip and, due to some reasons, the chip has gone bad (like in my case). You can bu ...

Dual sharing RTC

Necessity I have an old window AC at my lab, situated at the terrace. The AC needs to be run intermittently more so often when I’m out of the station and the lab PC needs to be cooled down during the intense noon time when the temperature shoots 35+ degree centigrade irrespective of summer or winter. Of course, the thermostat works! But it needs to be changed continuously else it will keep on running for pr ...

Getting started with NodeMCU development board for IoT

Since Internet of Things (IoT) projects are now quite popular, I recently bought a NodeMCU board to try IoT application development. The NodeMCU development board is an open source board based on ESP8266EX microcontroller with integrated Wi-Fi transceiver. Uploading programs to NodeMCU from any computer via microUSB port is very easy as it supports several programing languages. This makes NodeMCU a smart ch ...
