Where to connect GND on keyboard multiplexer circuit?

Hi all, I’m making a project to read my old calculator’s keyboard with an arduino and I’ve decided to design a new PCB and change it with the original one, as it’s easier than trying to hook into the old circuit. I’m working in EasyEDA and it’s nearly done, but I’m confused about how and […]

How is a diode used to regulate voltage?

Hi all, I was wondering how a diode is used to control the voltage here? Assuming the voltage coming in from the left is greater than the reference voltage provided by the potentiometer, the diode is somehow acting to ensure the voltage going out is equal to the reference voltage. How does it do this, […]

How to decide which key was pressed on a calculator?

Hi all, I’m trying have an arduino read key presses on my calculator. The calculator does it by pressing the keyboard membrane to the PCB and connecting two points, so each key has two of these points. I’ve soldered wires to two key’s contact points(four wires in total), and connected the arduino’s GND to the […]

Java Azure Function Not Executing Locally

Hi all, I’m working on Azure functions, I’m new to this, I have created a local java Azure function project using the below archetype: *mvn archetype:generate -DgroupId=com.mynew.serverlesstest -DartifactId=serverlessexample – DarchetypeGroupId=com.microsoft.azure -DarchetypeArtifactId=azure-functions-archetype – DinteractiveMode=false* *The template has a simple java function. Upon executing a “mvn clean package” command, function.json gets generated in the target folder for […]
