The main block, which will start the action and call the required blocks. To change the time slide the Slide switch 1 upwards. Take the solid hanger plate and place it on the hollow hanger plate, as the hollow plate will give some space to the nail inserted in the wall. The ring lets you hold the RGB to the clock.
Digital clocks can be used to tell time at a glance. They became quickly more popular than the older sweep hand clocks, now known as analog clocks. The time derived by analog clocks came from either a pendulum or a spring.

And you can choose what digit you want to power by connecting the negative leads of the display to ground and sending the data to the positive segment leads. Multiplexing works by switching between the digits one by one very fast and by so creating a illusion that all of the displays are working in the same time. The clock is made of six seven segment displays which make up the display. The below two blocks “Set Time” and “Set Date” are used to set the time and date in RTC which is found inbuilt in evive. We need to set the time and date using potentiometers and tactile switch of evive.

Wire pin 11 of the first 7490 to the clocking input of the second 7490.
Step 5: Advancing the Wall Clock
The LED will turn “red” at the position where the hour hand points to. I am able to do simple programs for the Arduino, but a clock is a bit above my pay grade, so I used their code. There are a few real-time clocks available for the Arduino, and after doing a little research, went for a DS3231, which seemed to be the best of the bunch.
While many digital clocks are available commercially, you can also build your own from components. Follow these tips to learn how to make a digital clock. Acquire the 4060, 4013, breadboard sockets for those parts, and all discrete support components identified in the data sheets. Build the 1 Hz time base on 1 corner of the breadboard.
Step 1: RGB LED in place of Clock Hands
All the electronic components were soldered to the PCB, and wiring for the LED and rotary encoder was attached as well. The Led’s do require a capacitor on the power wires, and a resistor on the data wire to the lights. I am not an electronics engineer, but simply followed the instructions for the lights. They are required to stop the 1st LED from failing, and also stop any spikes along the data wire. We can add as many functionalities as we want in our wall clock.
When i connect a 9V battery to it, only the 4 dots lit. I am confused maybe it's because of the wiring but i definitely did what it is written in there and in the diagram. Also maybe because of the resistors i used? By the way i used yellow LEDs and i used 150ohms resistor for current limitting.
The data sheet will show how to wire connect the 7805 and supporting discrete components. Take your chip and put it in the arduino board and put the program I have added with this step. As the name suggests us we will be using RGB LEDs instead of seconds, minutes, and hours hands.
Wire the output from pin 8 of the second 7490 to the normally closed contact of a single pole double throw switch. Wire the wiper of the switch to the clock input of the third 7490. I used a 5volt 2 amp plug pack to power the lights, and the Arduino as well. Wiring from the rightmost device to the leftmost device, wire the first s as a count by 10, a count by 6, a count by 10, and a count by 6. Wire the fifth 7490 as a count by 2 and the sixth 7490 as a count by 1 for the 12-hour clock.
It should still be cool to the touch but indent easily when you press it with your finger. When toasting the nuts, cool them completely before adding to the batter so they don’t melt the butter. Make sure your butter is just room temperature, the butter should sit at room temperature for about 1 hour. STEP FIVE- Press roughly a tablespoon of dough in your hand squeezing and rolling into a 1-inch ball shape.
Pendulums are unusable on moving platforms, such as a ship, and springs unwind more and more slowly as they release stored up tension. The use of sweep hands allowed these mechanical time bases to be presented in a mechanically driven display. With the perfecting of multivibrator chips, electrical circuits could be built that could accurately keep time under a wide range of conditions. As the time base had switched from mechanical to electrical, the time display had to follow suit. Display devices called 7 segment displays were designed to allow the time to be shown numerically.
