The KitGuru team has been over at Computex 2024 in Taipei - Leo managed to get some time at the GAMDIAS booth, where they were showing a lot of cases - many of which were new to us. Buy our merch ...

In this article, we present a new method to measure electroluminescence (EL) images of current half-cell PV modules without opening electrical contacts. The method uses the series parallel ...

Offshore wind farms (OWF) connected to diode rectifier (DR) and modular multilevel converter (MMC)-based HVDC confront challenges of surplus power induced by onshore AC faults. This paper proposes an ...

A three-amplifier instrumentation device only has the noninverting inputs connected externally, so adding capacitance on the noninverting inputs will not degrade the phase margin. Figure 7 shows the ...

LiquidCrystal Arduino library for I2C LCD displays used for STEM schools. Tested on HD44780 LCD connected to PCF8574 I2C. Original work by Frank de Brabander ...

OpenPLC is an open-source, free-to-use Programmable Logic Controller Suite, compliant with the IEC 61131-3 standard, and working with a range of hardware platforms such as Arduino, ESP8266/ESP32, ...

Figure 1 shows a typical converter schematic. The I2C bus is connected to PIN5 and PIN6, and the SPI bus is connected to PIN9, PIN10, PIN11, and PIN12. PIN8 is used to control the transmission ...

In this tutorial we are going to interface I2C 16x2 LCD and 4x4 keyboard with Raspberry Pi zero W. Throughout this tutorial, we will discuss about basics of I2C display and 4x4 display and how to ...
