Insert the DS1307 IC in the 8 pin IC socket with the notch pointing outwards from the PCB.Now you need to feed the correct time and date into the RTC module. You can remove this led from your PCB if you want. I can use it with a blink program to check the onboard DIY arduinos works or not. The second is also a 3mm led that is connected to the pin A0 of the microcontroller. The one at the right is the power indicator that is connected with 7805 with current limiting resistor. Another thing you may find odd is that there are two leds on board. That’s completely your choice, as long the connections are proper everything will work. I did this intentionally to reduce the size of this board. One thing you may find odd is that all the components are on the top layer of the PCB except some resistors and the 3V battery. Also note the orientation of the items before inserting the components in their place. Make sure that there are no solder bridges shorting two pins. You don't need any soldering station for this job.Īfter soldering. All these are through hole components and that will result a better as well as easier soldering experience. Place each component on the PCB as the diagram tells. Having a physical copy at the time of soldering helps a lot. Just make a print out of the circuit diagram and BOM. So if you are not feeling like reading through this page, then do check out this video -ĭo follow us here in Instructables and subscribe to our Youtube channel - Once you have received the PCBs, it time to solder the components on it. So without further ado let's start this process.īTW in our youtube channel we have uploaded a video on this same topic. So I will be using 7 segment display for this project. But I want the look of a more traditional digital clock that uses 7 segment displays to portray the digit on the front panel. You can use a LCD screen, OLED screen or even make a completely new display technique which will be out of the box. The main visible change is the way the time is presented to the viewer. There are countless number of ways to make a digital clock using Arduino or say any kind of microcontroller. You can find the link to that tutorial in the later part of this instructables. Previously We have made a binary clock using charlieplexing concept. This will be a short and simple project about how to make a digital clock using Arduino.
