I took it from some old device I can’t even remember what was that. Description I wanted to make a project by using stuff I had lying around and I came in this watch. You agree that the Information as provided here by RS may not be error-free, accurate or up-to-date and that it is not advice.

Soon I’ll post schematics and avr code. You should add a description of how it’s connected and why that’s meaningful to the project in order to have the best chance with the judges. The timer2 is set to overflow and it’s prescaled to And the really cool thing is that I made 2461 swag by myself and I feel proud of it: Similar projects worth following.
I have like this one.
I wanted to bend it’s top pin but I broke it, so I had to make it from wire. With Hz clock it overflows every 8 seconds. Similar to a bicycle computer but hackable, including different sensors and potentially connecting to and Android device via bluetooth.
Those yellow traces should be connected by using wire. About Us Contact Hackaday. I read hack-a-day really often and I’ve seen some cool projects about making watches even smart ones!
View all 9 components. When testing the display, I’ve noticed that when it is blanked it still drains about 1mA of current at 5V. I designed it like this on purpose, because battery in this way holds better in this holder: All babies today love teething on their parents phones. On the upper side of the PCB there are contacts for buttons to set minutes and hours. I solved the problem by not keeping it constantly on like mobile phone screens – they are turned on only when user is using them.

DL Intelligent LED Display using Arduino
Yes, delete it Cancel. You are about to report the project ” HPDL watch “, please tell us the reason. In the beginning I thought it will come quiet ugly and I’ll need to make a case for it, but now I like how it looks. The code is next. Sometimes you can even buy this type of battery from the store when it has less than 3 V left.
Unfortunatelly, uc barely fits in the middle of the display’s back and 4216 pinout traces of display and uc touches where they mustn’t. I ypdl I’d use it to turn on the display, but later I changed my mind so I left it unconnected.
Below there are contacts to attach a programmer. Sending feedback, please wait View all 4 instructions. It’s powerded by a coin cell. The most important thing is to set correct clock fuse for 32, crystal and to disable JTAG. It’s available at my github, I’ll just explain a little bit. Then I add 8 secs to the time variable. View all 2 project logs. When you press any of these when display is blank – it will only turn it on by powering and unblanking it.
Here is the link: Add to a parts list. Thanks for entering your watch to The Hackaday Prize. When the display is on, you have to wait 3 secs and then you can set the time.
The foregoing information relates to product sold on, or after, the date shown below. It easily firt into arduino pro mini.
BTW, in the foto you can see that I put the battery upside-down. Moreover the power-down sleep mode is used to reduce power consumptions of the uc. Please enter a message. Please select an existing parts list. According to the datasheet – up to mA and it’s a lot for a battery powered device.
Let’s start with PCB. Display falling tetris blocks on a oled screen made into an ear ring. Your Email Remember me. Already have an account? Unfortunatelly, these displays are getting extinct like nixies are.
