To execute all of this in Arduino IDE, there is a function called shift out having four parameters (see picture). When all the bits are completely sent, the latch is pulled high to actually reflect the data in the 8 output pins. The shift register determines that new data is coming by checking the status of the clock pin, if clock pin is high, the data is new. Then each of the 8 bits is sent one by one. The latch is pulled down before sending the serial data. Pin 9 is used for daisy chaining and is connected to next 74595. Pin 10 is called serial clear, and is used to clear the output of shift register, will be held high throughout the project pin 13 called output enable, as the name implies, enables the output, will be held held low. Pin 14 – aka serial input, Pin 12 – aka latch, Pin 11 – aka clock, are the control pins I talked about. Like all 74 series ICs, 8 and 16 are power pins. Pin number 1 through 7 along with pin 15 is the parallel output data. What I’m trying to say is just by using three pins, you can control lots and lots of digital devices. This shift register can also be daisy chained with another shift register to control even more LEDs, and the second one can be daisy chained with the next shift register and so on. And that is the problem because we will be working with a lot of LEDs in this project.Ī shift register consumes very less pins of the microcontroller, 3 in this specific case, and can control a large number of LEDs with it, which is 8 in this case. Even after combining them we only have 20 number of pins, out of which not all are output capable. An Uno has 14 digital I/O pins and 6 analog input pins. You might wonder why we need a shift register. We are going to use 74HC595 which is an 8 bit SIPO shift register that means it will take 8 bit serial data, and convert it into 8 bit parallel data. When pressing and, you can select the color used.There are four kinds of shift register – Serial In Parallel Out (SIPO), SISO, PISO, and PIPO.Press the button and you will see the Eureka screen, followed by the changing colors on the screen.Press the button and the time will start blinking.It might even be possible to re-use the RTC of the original clock PCB. I will not reveal the details of the RTC because it is not connected yet.Connect the wires according to the schematic.The hole should align with the USB connector of the Wemos. When you position it wisely, you can drill a hole in the back of the clock. This should provide a steady power supply. Attach the capacitor to the power of the led strip. DIN starts at the “o’clock” segment and zig zag all the way up to the “ten” segment. Stick the LED strips inside the clock: It’s 3, half 4, ten 3, quarter 7, twenty 6, five 4, minutes 7, to 2, past 4, one 3, three 5, two 4, four 4, five 4, six 3, seven 5, eight 5, nine 4, ten 3, eleven 6, twelve 6, o’clock 7.This is to prevent shortages from the LED strip to the PCB below. Put electrical tape on the place where you want to put the led strips.You can do that with a normal kitchen knife and a lot of patience. Carfully remove the filter from the front.1 x 1000uF 16V Elektrolytische Condensator.1 x GL5528 LDR lichtgevoelige weerstand.2 x WS2812B Digitale 5050 RGB LED Strip – 60 LEDs 1m. That is my favorite shop for electronics stuff in Eindhoven. This is the shopping list, you can buy it for example at TinyTronics.
