# Fitra - Arc Reactor using ESP32 and Web of Things
## Requirements
Requirement tools:
- SparkFun ESP32 Thing
- Jumper Male-Male 20cm
- Battery Lipo 3.7v 1000mAh
- Rainbow LED WS2812
- Solder
- Solder Iron
## HOW TO
### Datasheet and Soldering
The following datasheet is advised by my friend from SurabayaPy [Tegar Imansyah](https://github.com/tegarimansyah)
Connect SparkFun and Rainbow LED WS2812 with jumper by using the following
schema
| SparkFun | Jumper | LED WS2812 |
|----------|------------|------------|
| 13 | Connect to | DIN |
| VBAT/VUSB| Connect to | VCC |
| GND | Connect to | GND |
Use VBAT for battery power and VUSB for USB power
### Flashing Loboris Micropython
Clone the fork of Loboris Micropython repository, this repository has been
updated to allow PUT command to work with microWebSrv and fix for microWebSocket
based on [this](https://github.com/dhylands/MicroPython_ESP32_psRAM_LoBo) branch and latest update from [Loboris](https://github.com/dhylands/MicroPython_ESP32_psRAM_LoBo) master branch
```
$ git clone https://github.com/ariestiyansyah/MicroPython_ESP32_psRAM_LoBo.git
```
Config the micropython and build the Firmware
```
$ cd MicroPython_ESP32_psRAM_LoBo/MicroPython_BUILD/
$ ./BUILD.sh menuconfig
$ ./BUILD.sh
```
Flash it
```
$ ./BUILD.sh --port /dev/tty.usbserial-DN03F9EP flash
```
SparkFun connected to my mac using `/dev/tty.usbserial-DN03F9EP` port, this will be
different on each device, check it using following command
```
$ ls /dev/tty.usbserial*
```
### Install Gateway
Follow instruction from
[https://github.com/mozilla-iot/gateway/blob/master/README.md](https://github.com/mozilla-iot/gateway/blob/master/README.md)
to install Mozilla Gateway in your Raspberry Pi or PC/Mac.
### Web of Things Micropython
Clone fitra project
```
$ git clone https://github.com/ariestiyansyah/fitra.git
```

```
Rename file `config.example.py` to `config.py`, change variable SSID and PASSWORD value with wifi credentials, for example
```
SSID = 'FITRA'
PASSWORD = 'bahagialah'
```
Sync local files to ESP32 by using [rshell](https://github.com/dhylands/rshell),
you can also use ampy :) mine is rhsell.
```
$ rshell -a --buffer-size=30 -p /dev/tty.usbserial-DN03F9EP
fitra> rsync -v . /flash
fitra> repl
>>> Control-D # Soft reset
```
You will see spining LED in neopixel now.
### Adding RGB function and Property
Create sample display_odd function to display LED in odd number by
```
# src/neopixel/np.py
def display_odd(np, delay=DELAY, color=COLOR, saturation=SATURATION, brightness=BRIGHTNESS, clear=True):
for reactor in REACTORS:
if reactor % 2 == 1:
continue
np.setHSB(reactor, color, saturation, brightness, 1, False)
np.show()
time.sleep_ms(delay)
if clear:
np.clear()
```
Add property to enable it in gateway
```
# webserver.py
self.add_property(
Property(self,
'odd',
Value(self.odd, self.oddReactor),
metadata={
'@type': 'OnOffProperty',
'label': 'Display Odd Reactor',
'type': 'boolean',
'description': 'Turn on the Reactor',
}))
```
### Convert RGB to Hex
This function contributed by my partner in crime [Ady Rahmat MA](https://github.com/ngurajeka)
```
# webserver.py
def convertToRgb(self, color):
red = int(color[1:3], 16) / 256 * 100
green = int(color[3:5], 16) / 256 * 100
blue = int(color[5:7], 16) / 256 * 100
return (red, green, blue)
def convertToHex(self, color):
return int(hex(int(color[1:], 16)), 16)
hex_color = self.convertToHex(self.color)
hue, saturation, brightness = self.np.RGBtoHSB(hex_color)
```
## Lesson Learned
all problems found during the experiment.
### LED on USB power vs Battery power
The led does not run normally when connected with USB Power, it will run
smoothly on battery power.
