Neon Ticker

Neon Ticker

If you’re anything like me, you set timers multiple times a day. Boiling an egg? Set a timer. Brushing your teeth? Set a timer. Putting a limit on screen time? Set a timer. While most of the time it’s easy enough to do on my phone, I don’t want to have to rely on it for everything. Besides, sometimes my phone isn’t easily accessible, or it’s in my pocket and I don't want to have to set it somewhere to keep an eye on the time if i need to check it before the timer is up.  With the Neon Tennis device, I can now easily keep a timer somewhere close to where I often find myself needing one. In my case, I set a lot of timers while cooking, so I’ve got one on my fridge, ready to go whenever I need it. With the 32 LEDs on the device, and the integrated amomii Glow strip, a quick glance from across the room is all it takes to let me know approximately how much time I’ve got left until time’s up. Uploading the Project  If you haven't already uploaded the Neon Ticker code to your device, there are two ways to do it: 1.Use amomii Link. amomii Link is our proprietary tool for uploading code directly from our website. Go to  Neon Tennis Link and choose your project. Today we’re picking Neon Ticker. Read about the amomii Link tool.   2.Manual Installation: Go to the Toolbox, download the code and upload it to your device using the Arduino IDE (if you don't know what that means, use option one!) Go to Toolbox. How it Works Neon Ticker is set up to be used in 5 minute intervals, starting from 5 minutes, and going up. Simply use KEY 3 and 4 to set your time. Once your time is locked in, KEY 1 will get the timer started, and also acts as a pause function. KEY 2 will reset your timer. The amomii Glow strip will shine green as your timer begins, and transition to red as you slowly count down to zero. In addition, the 32 LEDs on the Neon Tennis PCB will slowly fill up, starting at the bottom right, and finishing at the top left, in order to give you a quick visual indicator of how far along you are in the countdown. Once the timer hits zero, a chime will go off, and the amomii Glow will flash to let you know the time is up.  Easy as pie! That is, it’s as easy as pie as long as you’ve got a timer set up so you don’t leave it in the oven for too long and burn the crust. But you’d never let that happen, right?

Neon Mind

Neon Mind

In our modern world, there’s almost nothing we actually have to commit to memory anymore. Whether you’re setting reminders on your phone, you’ve integrated some sort of task app into your daily routine, or you’ve got one of them fancy AI agents keeping track of your schedule, passwords, and anything else you might need to store, exercising them memory muscles is something can seem almost antiquated, in a way. What that means is that your actual memory and ability to recall information might not be the well-oiled machine that you’d like it to be. Don’t believe me? Set a timer for 5 minutes and go onto your video platform of choice. Watch 5 minutes of short form videos. Click or swipe whenever you want until the timer’s up. Done? Good. What was the third video you watched? Maybe that took you a bit to remember, or maybe you don’t remember at all. That’s not a knock against you, that’s just the world we’re in. One of the projects we’ve made for the Neon Tennis device is a simple, old fashioned memory game. Watch the LEDs light up, and repeat the pattern by pressing the corresponding buttons. The better you are, the longer the sequence gets. Stretch your memory legs and go for the high score. Challenge others to see who can remember the longest sequence! Uploading the Project  If you haven't already uploaded the Neon Mind code to your device, there are two ways to do it: 1.Use amomii Link. amomii Link is our proprietary tool for uploading code directly from our website. Go to Neon Tennis Link and choose your project. Today we’re picking Neon Mind. Read about the  amomii Link tool. 2.Manual Installation: Go to the Toolbox, download the code and upload it to your device using the Arduino IDE (if you don't know what that means, use option one!) Go to Toolbox. How to play Neon Mind is primarily a one player game. The goal of the game is to see how long a sequence you can commit to memory.  Starting at 1, the Neon Tennis PCB will light up one of 8 LEDs situated on the four corners of the device. Each LED has its own corresponding color on the amomii Glow strip, and also plays a  unique sound, if either of those help you to remember the sequence more easily. After the LED lights up and turns off, it’s your turn to press the correct button. For step one, simply hit the KEY 1-8 that’s next to the LED that lit up. If you did that right, the game continues. The game will now light up 2 LEDs in succession, and you must press two KEY buttons in the correct order to continue the pattern. Once successful, the game will continue adding one step to the sequence after every time you’ve successfully inputted the correct pattern. The official Guiness record for the longest memory sequence in this type of game is 100, set in 2024. Typically anything above 30 is considered an excellent score, whereas scores in the 8-15 range are considered more of an average score for normal play. While a good memory might not be as critical as it used to be, why don’t you give your memory muscles a good workout with Neon Mind?

Neon Tennis

You’ve put in the hard work, and the Neon Tennis project is finished. Now it is time to play. The main game for this project is, of course, tennis. Serve, return, volley, smash! If you know tennis, then I’m sure you’re quite aware of the potential for lots and lots of damage if you want to play a game of it inside your living room. With the Neon Tennis game, we’ve shrunk the game down to fit onto your device, and you’re way less likely to break a window when you play. Whether you’ve got a friend that wants to play a game with you, or you just want to test your skills against the machine, Neon Tennis puts the game in your hands. Let’s get started! Uploading the Project  If you haven't already uploaded the Neon Tennis code to your device, there are two ways to do it: 1.Use amomii Link. amomii Link is our proprietary tool for uploading code directly from our website. Go to Neon Tennis Link and choose your project. Today we’re picking Neon Tennis. Read about the amomii Link tool. 2. Manual Installation: Go to the Toolbox, download the code and upload it to your device using the Arduino IDE (if you don't know what that means, use option one!) Go to Toolbox. How to play You can start by choosing whether you want to play a one or two player game. If you’re playing against the computer, you can then choose the difficulty next.Once that's done, let’s get playing. Your serve!The row of LEDs on the left is the strength indicator for your serve; the fuller the bar, the stronger the serve. But, be careful, if you hold the button for too long, it's a fault. Double fault, and you’ll lose a point. When it comes time to return the ball, you have some options. You have two return buttons on both the left and right side of the board. The outer buttons will return the ball straight back (up the line), and the inner buttons will return the ball diagonally (cross court). So that’s it? Not quite. The colored LEDs also come into play. You must time your return properly. Press the button when a green LED is lit up, and you’ll miss the ball entirely. Press it when yellow is lit, you’ll return it at a regular speed. Press the button when the red LED is lit, and your return will get a speed boost! Returning the ball when the LED is red multiple times in a row will keep increasing in speed, making it much harder to hit! For now, that’s all you really need to know. For a more in depth description of the gameplay and rules, they can be found here: Official Neon Tennis Rules Now you’re ready to have a little fun with your amomii Neon Tennis! You’ve put in the work, after all, so give it a go and practice smashing aces against a friend, or the device itself!
