My plan is to design a PCB for a switchboard. By a switchboard im wanting it to be compatible and be able to input functions into my PC. E.g switching a switch would input E. Im pretty sure ill be able to code this and everything but i need help with the schematic so i can design the PCB. Im using EasyEDA for this.
Could someone help with this because i have no clue how i would make a switch tell the arduino that it has been inputted. thanks
Your post says very little we canuse to help.
It’s very clear in your mind, but I have no idea what signals you want to switch, or why.
Maybe a block diagram defining the external sources and destinations of up your ‘signals’…
By "switchboard", do you mean "keyboard". You mentioned "E", implying you want several letters other than "E". Keyboards are amazingly complicated and you'll have a miserable time if you try to design a PCB for one. Possibly, you mean something like a 12 key or 16 key keypad. These are also difficult to make at home and amazingly cheap, so better to buy. If you just mean a few switches, then you just need the switch and at least a resistor and maybe a capacitor. One end of each switch is usually wired to 0V and the other to the resistor and to a pin on the Arduino or whatever. The other end of the resistor is usually wired to +5V, or maybe +3.3V for some modern ICs.
Good luck.
I seriously have no idea what you are talking about.
Are you able to have another go at trying to describe what you are trying to do. If you provide rubbish requirements you will get rubbish responses from the forum.
Do you mean the 'switchboard' would act like a keyboard and type letters, like 'E', when the switch was moved? Or are the 'switches' momentary buttons? For that, it would be best to start with a board that has built-in USB support like the Arduino Leonardo or Arduino Micro. Then you could use the Keyboard library to type characters on the connected PC.
