I am working on a project within my company that involves a relay board used to control three different motors when an external 24V button is pressed. The existing setup works based on this principle.
Now, I have been tasked with designing a new board that maintains the current logic while...
Hi, I have a problem where a simple bush button makes a 3.2V into a 2.8V.
I wonder if there is any way to fix this or if every button does this.
Thanks in advance :-)
Hi everyone, I’m very new here and I’m currently working on a very small project that seemd as if it would be simple at first but is proving to be harder than expected with little to no tech knowledge as of yet. It’s a project for my cat & new kittens. They have a laser cat toy that turns on...
I'm attempting to make something like a keypad for a microcontroller, but instead of using a key matrix I've decided to have each key press generate a specific binary code by creating a connection between Vcc and specific output wires. For example, if I wanted the "E" key to correspond to the...
Hi folks, for a uni project I’m creating a synth using an Arduino. I want to have at a minimum 8 buttons for an input but I’m restricted to using only 1 or 2 input pins. Therefore I wanted to use an ADC to convert the input to binary values.
I wanted to use no IC’s if possible so tried using an...
Hello,
I am studying a schematic, and am not sure how this reset switch is supposed to work:
I cannot find any other switch that uses this symbol, and it just looks like all of the pins are shorted to ground. I don't understand why/how this switch works on the actual board. Is anyone able to...
Let me just state: I'm a totally newb (some entry-level Arduino and breadboard tutorials under my belt) and my vision is vastly outside the scope of my abilities, but I'm here to get some broad tips and feedback so that I can figure out where to begin on my path towards actualizing this project...
