click the UPLOAD button in the Arduino IDE, wait for the sketch to be compiled and uploaded, then verify the SERIAL MONITOR again, if you have a line with 'Flash Chip configuration ok' then the programming options in the Arduino IDE are good. to put the ESP board in programming mode, gently push the PROG switch and keep pushing, then push and release the RESET switch, THEN(!) release the PROGRAM switch, in the SERIAL MONITOR you must see a garbled line after the ready line (see image) you will see something like in the image bellow with the 'ready' word on the last line, it means the ESP Board is working and you can find on your phone a new WiFi Access Point open a serial monitor (TOOLS - SERIAL MONITOR), make the configs (Both NL&CR, 115200 baud) and push the RESET switch on the breadboard adapter open in Files-Examples-ESP8266 the CheckFlashConfig sketch and then make the configuration options in TOOLS like in the image (you will have another COM port eventually) insert the ESP-01 Board in the breadboard adapter and connect the USB to Serial converter to an USB port of the computer install in Arduino IDE the ESP support libraries - more here download the source for the Verbis word clock On the display you will see an animation like bellow. On the adapter I soldered a switch (PROG) between GPIO0 and GND pins and a switch (RESET) between RST and GND pins.Īfter correctly flashing the ESP-01 module, start the clock. You can see in the images the wiring between these two modules: 3.3v-RED, Ground-BLACK, RX from the converter to TX on adapter-PURPLE, TX from the converter to RX on adapter-GREY. Also to make the programming easier, I used a breadboard adapter like this and I connected it to the USB to Serial converter. My way for flashing the ESP-01 is using an adapter with a PL2303 chip (USB to Serial converter). Schematics- Very simple, made with Fritzing, see the image bellow. Also I opted for a separate DC connector because it is simple to replace a defective power supply The power supply is 5v and 1.5A maximum, it is rather enough because not all leds are lightened up at full brightness and full white. I used this connector because it permits easy assembly-disassembly of the enclosure. You can read more in Getting Started With NeoPixel / WS2812 RGB LED by Open Green Energy. Led Matrix 64led RGB Matrix with WS8212 IC The ESP-01 requires to be powered with 3.3v, I used here a 4pin module. (For example you can read this good instructable by TonesB ESP8266 WiFi Module for Dummies) II.The ElectronicsĬheap and versatile microcontroller module with WiFi capability, if you don't know about it there are many howto's on the net. The files on Tinkercad are based on this type of boxes. I used some already purchased jewelry boxes, I only designed a new box base because the boxes were too tall. The files that you can 3d print are also on Tinkercad. I cut off the layout with a pair of scissors. I got very good results with a cheap inkjet printer and standard white copier paper. You can print the file repeatedly on the same sheet of paper to achieve a good, opaque, black background. You can make your own display layout based on this SVG file, I used Word Search Construction Kitsoftware to generate a words layout for the time display. The SVG file for the Printed Paper Sheet is attached, and it can be edited with Inkscape. The STL file for 3D printing can be downloaded from Tinkercad The 3mm grey smoked plexiglass sheet can be cut from a bigger sheet, obtaining the required 80x80mm dimension. The dimensions I used are: width - 120mm, first part length - 180mm, second part length - 50mm, 15° bending angle. So I ordered several supports from an advertising company that makes all kinds of plexiglass objects. The plexiglass support can be also be made DIY but for an amateur it is not very easy to cut and blend plexiglass. I also asked for an accurate dimension, I didn't want the frame to be too big for the 3D printed plastic grid. I ordered my frames with a specific dimension: the framed photo, in my case object (display) is 80x80mm. But a simpler solution would be finding a framing company where you can order a personalized frame with your required dimensions and you can choose from many frame types. You can make your own frame, there are a dozen of articles about this, everywhere on the net. minute by minute time indication (not by 5 minutes like standard word clocks), dynamic time display and amazing flexibility for future ideas.it is possible to have multiple languages.opensource web server for easy management.very affordable, cheap electronics and other parts.
