If you've ever wanted to add an unconventional display to your project, you've no doubt come across the magic that is RGB LEDs. This ring consists of 12 of these super (and when mean SUPER) bright RGB LEDs placed into a ring and integrated with the ubiquitous one-wire WS2812 controller. All you need to do is download the easy-to-use AdaFruit Neopixel library for your microcontroller of choices (there's support for Arduino, Teensy and even the ESP8266). This ring is easily able to be powered straight from USB without the need of external power. The great thing about these LED rings, like all WS2812-driven RGB LEDs is that you only need a single pin to write to all your LEDs, as the data out pin of the each LED is connect to the data in pin of the next. Just keep in mind - each LED required 3 bytes of memory (one for each RGB colour), so when driving a large number of RGB LEDs, memory on the lower-spec side tends to become an issue. You'll also need a logic-level converter if your microcontroller doesn't use 5V logic. Power requirements Pay careful attention when driving a large number of these at full power. According to our measurements, each RGB LED uses about 30mA when driven at its maximum, although the datasheet specifies up to 60mA.  If you're going to be driving more than one ring, you'll need to replace the USB power with an alternative supply 5V with the required current: Required current = Number of LEDs  x 30mA OR Required current (extra safe) = Number of LEDS x 60mA. Hookup There are two extra steps that you should take in order to ensure your RGB LED Ring is protected. Place a 220-1000uF capacitor over the VCC and GND pin of the LEDs. This is to protect any voltage spikes from accidentally damaging them. Place a 500Ohm resistor (or thereabouts) between the Data In pin and your microcontroller. This is to prevent any noise interfering with the data signal. Documentation WS2812 Datasheet

HT12D Decoder 18 DIP IC HT12D Decoder IC is a 212 series for remote control applications manufactured by Holtek. It is commonly used for radio frequency (RF) wireless applications. By using the paired  HT12E encoder and HT12D decoder we can transmit 12 bits of parallel data serially. HT12D simply converts serial data to its input (may be received through RF receiver) to 12 bit parallel data. These 12 bit parallel data is divided into 8 address bits and 4 data bits. Using 8 address bits we can provide 8-bit security code for 4-bit data and can be used to address multiple receivers by using the same transmitter. HT12D is a CMOS LSI IC and is capable of operating in a wide voltage range from 2.4V to 12V. Its power consumption is low and has high immunity an noise. The received data is checked 3 times for more accuracy. It has a built-in oscillator, we need to connect only a small external resistor. HT12D decoder will be in standby mode initially ie, an oscillator is disabled and a HIGH on DIN pin activates the oscillator. Thus the oscillator will be active when the decoder receives data transmitted by an encoder. The device starts decoding the input address and data. The decoder matches the received address three times continuously with the local address given to pin A0 – A7. If all matches, data bits are decoded and output pins D8 – D11 is activated. This valid data is indicated by making the pin VT (Valid Transmission) HIGH. This will continue until the address code becomes incorrect or no signal is received.     Used to convert Parallel 4-bit data  to series data     Highly useful in wireless communication projects involving RF or IR     Remote controlled systems like garage doors, Car alarm system, Car door controls etc.     Can be used in Home automation for short range remote switching     Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. This item is available in stock and is not drop shipped. This avoids delays, customs charges and extra VAT.

Power Pins: GND - this is the common ground for all power and logic BAT - this is the positive voltage to/from the JST jack for the optional Lipoly battery USB - this is the positive voltage to/from the micro USB jack if connected EN - this is the 3.3V regulator's enable pin. It's pulled up, so connect to ground to disable the 3.3V regulator 3V - this is the output from the 3.3V regulator. The regulator can supply 500mA peak but half of that is drawn by the ESP32, and it's a fairly power-hungry chip. So if you need a ton of power for stuff like LEDs, motors, etc. Use the USB or BAT pins, and an additional regulator Logic pins: This is the general purpose I/O pin set for the microcontroller. All logic is 3.3V The ESP32 runs on 3.3V power and logic, and unless otherwise specified, GPIO pins are not 5V safe! Serial pins: RX and TX are the additional Serial1 pins, and are not connected to the USB/Serial converter. That means you can use them to connect to UART-devices like GPS's, fingerprint sensors, etc. The TX pin is the output from the module. The RX pin is the input into the module. Both are 3.3V logic I2C & SPI pins: You can use the ESP32 to control I2C and SPI devices, sensors, outputs, etc. If using with Arduino, the standard Wire and SPI devices work as you'd expect! Note that the I2C pins do not have pullup resistors already! You must add them if you want to communicate with an I2C device GPIO & Analog Pins: There are tons of GPIO and analog inputs available to you for connecting LEDs, buttons, switches, sensors, etc. Here's the remaining pins available. Bottom row: A0 - this is an analog input A0 and also an analog output DAC2. It can also be used as a GPIO #26 A1 - this is an analog input A1 and also an analog output DAC1. It can also be used as a GPIO #25 A2 - this is an analog input A2 and also GPI #34. Note it is not an output-capable pin! A3 - this is an analog input A3 and also GPI #39. Note it is not an output-capable pin! A4 - this is an analog input A4 and also GPIO #36 A5 - this is an analog input A5 and also GPIO #4 21 - General purpose IO pin #21 Top row: 13 - This is GPIO #13 and also an analog input A12. It's also connected to the red LED next to the USB portIt's also connected to the red LED next to the USB port 12 - This is GPIO #12 and also an analog input A11. This pin has a pull-down resistor built into it, we recommend using it as an output only, or making sure that the pull-down is not affected during boot. 27 - This is GPIO #27 and also an analog input A10 33 - This is GPIO #33 and also an analog input A9. It can also be used to connect a 32 KHz crystal. 15 - This is GPIO #15 and also an analog input A8 32 - This is GPIO #32 and also an analog input A7. It can also be used to connect a 32 KHz crystal. 14 - This is GPIO #15 and also an analog input A6 http://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers Here are: https://espressif.com/en/products/hardware/esp32/overview 240 MHz dual core Tensilica LX6 microcontroller with 600 DMIPS Integrated 520 KB SRAM Integrated 802.11b/g/n HT40 Wi-Fi transceiver, baseband, stack and LWIP Integrated dual mode Bluetooth (classic and BLE) 4 MByte flash On-board PCB antenna Ultra-low noise analog amplifier Hall sensor 10x capacitive touch interface 32 kHz crystal oscillator 3 x UARTs (only two are configured by default in the Feather Arduino IDE support, one UART is used for bootloading/debug) 2 x I2C (only one is configured by default in the Feather Arduino IDE support) 12 x ADC input channels 2 x I2S Audio 2 x DAC PWM/timer input/output available on every GPIO pin OpenOCD debug interface with 32 kB TRAX buffer SDIO master/slave 50 MHz SD-card interface support Package included: 1 x Wemos® TTGO ESP32 Dev Module WiFi + Bluetooth 4MB Flash
