I wanted a flippy do I could project so the entire class could see it. I also decided I wanted one that would do the math for me so I don’t stumble all over myself if I am not paying attention to the addition. 🙂 [Make your own copy here.](https://docs.google.com/spreadsheets/d/1v4_WCGzdvi6_X5fj_vGu3xt3D3TWGTET5q9yTRJljr0/copy) [Screen shot visible here.](https://drive.google.com/file/d/10YrstOv_VQDTJZAAtOFePAvG8HUexMnl/view?usp=sharing) ---

UPDATED Digital Flippy Do! Now the Digital Flippy Do is easier to use with only a mouse. Clicking on the check boxes changes the binary number from a 0 to a 1 and back again. Also added a feature to help with creating binary notation from decimal notation numbers. The right panel of the Flippy Do allows a decimal number to be entered. As binary notation changes, the decimal number decreases to show how much closer you are to having the correct Binary number.

This is amazing! I’m going to use this to demonstrate the flippy do in virtual class. Thanks for creating it. I noticed that your formula in R9 had an error when you got within 1 of the number or created the number exactly. I updated the formula and it seems to be working now (I just changed \<1 to \<0). Here’s my update to cell R9 in case anyone needs it: =IFS(R5="","",R5-N9\<0,“Binray Value Too Large”,R5-N9\>0,R5-N9,R5=N9,“Great Job!”) ---

Hi everyone! This is a link to the Digital Flippy Do with the correction to the code made so it works better and the link forces you to make a copy. No need to request access any more. Please use this link and ignore the previous ones.

I really like this idea. I created a [Code.org](http://Code.org) app that does a similar job. I was excited to show students what type of ‘prototype’ apps they could make later in the year.

This is awesome! I had thought of making an app version of the Flippy-Do myself but you’ve saved me a TON of time! Thank you for sharing! ---

No problem at all. I made it for my own class. I just happened to get it done earlier than you did. Super useful for students joining on line this year. ---

This is great! I really like that you made it in app lab which the students can also use to make their own projects. ---

I apologise for asking what might seem like a stupid question, but, do you think you could include instructions to how this works? 😊 ---

Haha, not at all. Just type in the 1 or 0 in the correct slot and it will calculate the human readable number for you. ---

You bet! It has served me well over the years.
