Wooden Digital Clock is controlled over WiFi




Wooden Digital Clock with

– Time, Temperature, Humidity, Alarm

Wooden Digital Clock is controlled over WiFi




– WiFi controller through web browser

– Advance display config

– Stop alarm by vibration sensor

size : 64 x 64 x 79 mm

i use PLA with wood veneer instead of full wood

my room’s too small for put woodworking tools

If want view detail all steps, you can watch video

Step 1: PCB – Display

This step for make PCB (two layer) display module (if cannot do, you can find PCB Manufacturing Service)

I use MAX7219 for led driver and display with Led CEM3491, it have two dots for sec and upper dot for temperature

But CEM3491 is Common Anode, MAX7219 for drive Common Cathode, so must reverse pin Digit and Segment

Material list :

– (x1) CEM3491BY (0.39″ Common Anode 4-Digit 7-Segment Display Amber Color)

– (x1) MAX7219 (Led driver display)

– (x1) 10k Resistor

– (x1) 10uF Capacitor

– (x1) XH2.54-5P (5Pin Straight PCB Male Box Header Bar Connector)

Step 2: Program

I have complete program firmware, you just upload it to STM8S005C6T6 by software STVP-STM8 with file controller.s19

STVP-STM8 : http://www.st.com/en/development-tools/stvp-stm8….

hardware for upload : ST-LINK

if see “PROGRAM MEMORY programming completed” it mean done

about upload firmware, view detail in video at 10:35

Step 3: PCB – Controller

Next for solder microcontroller STM8S005C6T6 and other parts for complete PCB controller

button for reset wifi config, just hold down 3s and buzzer will fire beep sound

Material list :

– (x1) STM8S005C6T6 (Microcontroller)

– (x1) ESP8266-12 (WiFi module)

– (x1) ASM1117-5.0 (voltage regulators 5V)

– (x1) ASM1117-3.3 (voltage regulators 3V3)

– (x1) 470uF Capacitor

– (x1) 1uF Capacitor

– (x3) 10uF Capacitor

– (x2) 4.7k Resistor

– (x1) Mini Pushbutton Switch (4Pin)

– (x1) SW-420 (Vibration sensor)

– (x1) DS1307 (Real Time Clock)

– (x1) 32.768 khz crystal

– (x1) CR2032 battery

– (x1) CR2032 battery holder

– (x2) XH2.54-2P (2Pin Straight PCB Male Box Header Bar Connector)

– (x1) XH2.54-5P (5Pin Straight PCB Male Box Header Bar Connector)

– (x1) XH2.54-4P (4Pin Straight PCB Male Box Header Bar Connector)

– (x2) Cable Double Connector XH2.54-2P

– (x1) Cable Double Connector XH2.54-5P

– (x1) Cable Double Connector XH2.54-4P
