TISHITU "LED Glow" Bluetooth Arduino & Android App Inventor (MIT) Tutorial Part-2 @TarunShrivastava

Tishitu explains
Bluetooth is a type of wireless communication used to transmit voice and data at high speeds using waves of radio. It’s widely used in mobile phones for making calls, headset and share data. This type of communication is a cheap and easy way to control something remotely using arduino.

HC-06 module has 4 pins to be connected to arduino, they are:

RXD
TXD
VCC
GND

RXD will receive data from arduino; TXD will send data to arduino; VCC is the power supply (3.3V 6.6V) and GND is the ground.

You gotta pay attention about the RXD level, some modules work with 5V, but this one works with 3.3V, and arduino TX will send a 5V signal, then it needs a voltage divider.]
The sketch for this Project is very simple, all you have to do is check the serial port if there’s data available.

Using an android phone with a spp bluetooth apk, the command is sent to bluetooth (RX/TX). What happens is the bluetooth module communicates with android's bluetooth using a profile called SPP (Serial Port Profile). It emulates a USB Port connected to arduino and android.

TISHITU Hydrogen Home Gas HHO Stove with LPG, Risk Free with no Flash Back from Hydrogen Fuel Cell.

$HHO hydrogen fuel cell welding high pressure flame Tishitu explains What is oxy-hydrogen generator: Oxy-hydrogen gas Generator consumes water and electricity, electrolyze water into H2 and O2, we can use H2 and O2 as source of flame replacing acetylene or natural gas or other fuel. It can be used for welding, cutting, polishing, brazing, glass processing and jewelry processing. Also can burst with other fuel together for heating. Why we use Okay oxy-hydrogen generator: 1. Portable, flexible and movable. 2. Without any pollutants, toxic fumes, or public nuisance, hydrocarbons, carbon monoxide, or carbon dioxide. 3. Energy Saving more than 30% compared with traditional LPG, Propane, Acetylene fuel. 4. The cost of electricity and water reduces more than 40% compared with LPG, Propane, Acetylene fuel. 5. Maximum safety with perfect combination by multilevel wet-type flashback arrestor technology, automatic safety valve technology and dry-type fire resistance technology. 6. Excellent welding and cutting quality. And there is built-in flame temperature adjusting device, it can diffuse the small concentrated flame to big flame. 7. High Mobility with wheels to move. Dont need to compress air, dont need air compressor, transformer, gas cylinder and other auxiliary appliances. 8. The flame temperature is over 2800oC, it can melt refractory metals and none-metals. Calorific value is 34000 kcal/kg. 9. Low Heat Dispersal. Multi-functions application: 1. Gas welding and flame spray painting. 2. Welding, mending, repairing, kinds of jewelry made of platinum, gold, silver, copper, stainless steel etc of Jewelry Industry. 2. Direct fusion and welding, enameled wire, computer wire peeling, welding LED wafer, flame-treating circuit board of Electronic Industry. 3. The thermal processing of glass and quartz glass. 4. Organic glass Polishing. 5. Welding metal fittings and mending sand holes in dentistry, no-carbon flame disinfection. 5. Quartz glass tube Sealing and etc. Ampoules bottles Sealing. 6. Welding or heat treating small metal parts. 7. Carbon Steel Cutting, continuous casting slab cutting. 8. Removals of carbon deposit in the combustion chamber of internal combustion engine such as cars. 9. Catalytic combustion: Burn with other fuels together as for boilers, cooking stoves, melting metals. Unique Patented Features of Okay Energy Oxy-hydrogen Generators: 1. High frequency inverter constant current power supply which development is based on patented technology IGBT module. 2. Electrolytic Cell adopts precise mould to integrated formed, prevent from explosion and leakage and it is insulation shell, wont charged. 3. Dynamic self-circulation electrolytic process, built-in purifier, clean the electrolysis cell automatically. 4. Centrifugal water oxy-hydrogen separation device, achieve water and gas separation 100% 5. Polar plate adopts special activity alloy material surface treatment, low overpotential and no leakage. 6. All internal pipeline is seamless stainless steel tube, no any rubber hoses, ensures the safety and reliability. 7.Perfect conbination by Multilevel wet-type flashback arrestor technology, automatic safety valve technology and dry-type fire resistance technology, ensure safety and reliability. 8. Full automatic water degree detection technology, achieves the functions of early warning of water level, complement water auto and protection when water shortage without machine shutdown.9. Digital Human-Computer Interaction interface, be convenient to operate. 10. Precise flame gun and kinds of precise nozzle sold free with machine to meet different process demand. -~-~~-~~~-~~-~- Please watch: Lifi Communication by Arduino UNO Download Project https://www.youtube.com/watch?v=c4gC8dbaiZg -~-~~-~~~-~~-~-$
