Logic Board

WHY DOES THIS APP ASK FOR CAMERA AND MICROPHONE PERMISSIONS?Because you can actually use a light sensor (camera) and a sound sensor (microphone) in LogicBoard circuits! How awesome is that?! And you can use the camera flashlight as output component. And yes indeed, that means you can make a torch which turns on in the dark using LogicBoard!! (won't run in the background, it's only about the principle of logic circuits)
Simulate electrical logic circuits on your Android device using Logic Board! To learn how, read the instructions below or in the app.

INSTRUCTIONS1. Add componentsTouching a white box will popup a menu. From this menu, you can select the component you want inside the box. If you have picked a component, the component will be drawn inside the box. When you touch it again, a new menu will appear.

2. Connect componentsInside this menu are two important options: 'Connect' and 'Disconnect'. If you want to connect the component to another one, you have to follow these steps:
* Choose 'Connect
* Optional: select socket
* Select target component and socket

3. Special settingsSome components have special menu items to change custom variables like the frequency of a buzzer or a pulse generator.

4. Saving boardsThe board is automatically saved. From the menu you can rename it, delete it and create or load other boards.

Halpfull app Thanks

I think it's really awesome, but it would be better if you added more things in the output and also make it so wires don't go over the number on the counters. It would also be beneficial if you added a delay. One issue that I constantly come across is the fact that it keeps crashing if I try to clear more than two things in a row without waiting in between. If you could fix this I would gladly give five stars!

Funny as hell. Built a vocomm circuit that is connected to my on-board LED flashlight. Operates in game mode and somewhat flashes in time with music and responds to voice commands. My only beef is no 555 timers or pnp/npn transistors. Download this app.

Keep this going and add more gates and chips. Some 'active' inputs would be nice on some of the features like the pulse generator so it can be restarted. Otherwise this is wonderful for engineering theories and just practicing logic problems. Great work. The design is nice too!

This is an excellent app!! I use it ALL THE TIME for work, designing my own chips, etc. It would be awesome if.. i.e. I built a JK flip flop, shift register, etc and could duplicate it to allow chaining of those devices, etc. so you don't have to recreate them one at a time for more complex designs... STILL 5+ STARS!! ...and ONE question, I feel kind of silly asking, but how do you change the lead connection colors as shown in your pictures..?? (i.e. output to another input, etc..??) THX!!

If this app could work even when the screen is off, that would be perfect.

I love this so much, this is the best logic app on Google play, with a little tweaking this could be even better!

I love to app but I have small question: how do you use the comparetor? It will be nice to know Thanks. Great app

Great app, but missing tools like custom components, copy paste, exe

man. Mar 22, 2017

This is amazing, I like it so much! I use it for projects and and sometimes memorising gates, 5 stars.

Jar. Jan 8, 2016

love it hope there will be even more features eventually

a must try

REN. R. Jul 30, 2014

Its really entertaining the work, but I faced an issue, I am not able to connect one gate output and a toggle switch together as an input to one other gate...also please make the connections flexible, so that it will not overlap or run over other components... resizing option for component will also be helpful, Please rectify, Then 5Stars

Upon simulation of a IC that is designed to use delay, it seems the app dose not have any sort of buffer implementation from what I have seen and dose not have a buffer gate witch comes in handy for most timed logic ic, the GUI is actually pretty well built if you ask me , its not the best but it outruns other logic sim's GUI's that have have toyed with , besides the low workspace. This app has great potential it just needs a little more work.

This needs more work such as a better variety of components, such as JK and D type flip flops, a 4 bit BCD counter and BCD to 7 segment counters. Also an undo last action and component labeling system.

It's hard, i'm not going to give a bad review and ruin somebody's chances of absolutely loving this game, but it just needs a more in depth tutorial because a wall of text just isn't good enough to make something thats good. I'd say 5/10 needs better tutorial.
