With this free app, your employees can clock-in and record their breaks on the same device you’ve got sitting on your counter. We’ve designed a time clock specifically for the Clover Mini. Now, with the free Homebase app, you can turn this Clover Mini into a time clock too. Last week, First Data launched the Clover Mini, a “smart” terminal that can do a lot more than swipe credit cards. If you need to upgrade your terminal, why get one that just accepts payments? Now if you were upgrading a ten-year old phone today, you’d probably get a smart phone that could do a lot more than make calls. For example, 7 -> S_ _ EVEN.The EMV deadline is only 99 days away, which means it might be time to upgrade your terminal. moreover, not all the hour words are shown as one word. The attached Arduino code should be quite well commented and understandable if one wants to adjust something.Īs place is limited I show time with 5 minutes intervals. I had a normal phone charger as the power source and that provides good reference ground. In the attached video you can see that I'm not holding the ground button when I'm "pressing" the buttons. When using power from a wall adapter the ground should be good enough. Use one hand to touch the ground button and the other for “pressing” the buttons. That’s why we have the fourth "ground button". Ground is floating and the ground is not well defined. When you are using a battery as the power source then just pressing the buttons (screws) doesn’t work very well. It's quite tight fit, thus placing the components crucial for good fit. Squeeze everything in and close with WordClockFrame5. Use some tape to isolate the open contacts. If yes, then proceed.īefore covering it with WordClockFrame5. Program the Arduino and test if everything is working as it should. They will be used later to adjust the time and screen brightness. Looking from the front the screws are- ground, brightness, minute and hour. Place there screws and fix with each screw a wire. On top of WordClockFrame4 are four screw holes. Be careful not to fasten the screws too much as it will bend the letter panel (improvement possibilities). Place the whole package in the WordClockFrame4. I used a large A4 size paper and after inserting (temporarily) the screws I cut the excess paper with a knife. You can insert all the screws to make sure that the holes are large enough and the paper has holes in the correct places. I used the paper to blend the light little better. Place WordClockFrame1 on the LEDs, then comes a sheet of normal paper. Make sure that the input side is one the left when facing the front of the LEDs. Now we can place the matrix in the WordClockFrame3. Solder the wires on the back side of the matrix PCB. The soldering is the best way as we need to solder there wires that will be connected with the Arduino. That needs to be remove by soldering or cutting. My LED matrix came with soldered header on the input side. Use a special tool or just a screw and some force. WordClockFrame2 would be easiest with a laser cutter, but I printed it out. The button working principle is exactly the same as I have shown here. At the beginning I wanted to use the fixing screws as the buttons, but I didn't have long enough screws and had to adjust the initial plan. I used capacitive touch function to register the button pressing. The video shows a larger version of this word clock, but the functionality is the same. I don’t have any problems with soldering, but I was looking a way to reduce time consuming work. The control can be very easily made with an Arduino and here is very little soldering needed. That gave me an idea- why don’t I use the LED matrices. Coincidentally on that time I saw a LED matrix modules. I thought about using a PCB and soldering LEDs on it. I dint have access to either of them, but I have 3d printing access. Basically, all the designs I have seen are using fancy vinyl or laser cutting. After long time thinking I found a nice way that I thought would be the easiest.įirst, I thought how could I make the word panel. Somehow, I’m always fascinated from the clocks and I wanted to build mine. I have seen several nice word clock designs here in Instructables and other places.
