![]() Usually you only need to pair them when connecting to a computer, most modules auto pair when in range of each other. What are you sending, and how far do you need to go?Īdded: forgot to mention, bluetooth works in pairs and must be "paired" to talk to one another. (Buffer size)Īlso again it is a little more confusing when just starting out. (Surroundings effect data loss too)ĭownside: the virtual wire library limits you to about 27 sendable characters at one time. If you use a high rate, then your range is about 30 - 40ft, and your data is 99% all there. Lower rate means further distances 150 - 170ft (open space), but more likely to lose some data. It's range is mostly based on the transfer rate. RF use the virtual wire library, which not going to lie, can be a little confusing at first. (Aprox 50 - 60ft, depending on surroundings). However if you can manage to find a LE(low energy) bluetooth module, you can go further. It really depends on what your sending, if you need to receive anything, range and complexity.īluetooth communicates serially so it uses the Arduino's serial port (Tx Rx), and in doing so by using the serial connection you can easily send and receive data.ĭownside: Bluetooth is a little sluggish but has better quality also your limited to about 30ft. Voice text and arduino text code must be the same for it to work (Case sensitive).I've used both and i'm currently using RF. Any Language can be recognized based on your phone google recognition. This mode use google tts & speech recognition. This mode lets the user control IOT applications using voice command thru arduino.(NEED INTERNET) not holding serial value for UP, DOWN, LEFT, RIGHT is "S" and for SQUARE, TRIANGLE, CIRCLE, EXS is "s". NOTE: UP, LEFT, RIGHT, DOWN, SQUARE, TRIANGLE, CIRCLE, EXS Buttons can be hold. Using this controller you can control your RC car forward, Turnleft, turnright, backward etc. Link: Sample Connection of RC Car Bluetooth control Using 3rd party IP CAM (copy the IP address) - Must be the same network Using relay you can control your lights i.e bulbs or any appliances for IOT applications. Up to 18 channels (D2-A5) Relay can be used. Sample Connection of Relay Bluetooth control You can add LED up to 18LEDs (D2-A5) to control. ![]() Sample Connection of Simple LED Bluetooth control ĭigital pins 2-13 & Analog pins A0-A5 can be used. Anything Digital OUTPUT i.e LED's, Relay etc.Arduino Pins D0 & D1 are used for Bluetooth Module.īefore uploading to arduino disconnect first any connection in PIN D0 & D1 (TX,RX). (will update more mode soon).Ĭheck the provided Schematic Fritzing for connections. You can choose from Switch ON/OFF mode, Gamepad mode, Voice Recognition mode. Change Bluetooth name and password - AT commands.Sample Connection of RC Car Bluetooth control.Sample Connection of Relay Bluetooth control.Sample Connection of Simple LED Bluetooth control.Any bugs or error can be reported or send to my email. Compatible from Bluetooth 2.0 to Bluetooth 5.0. ![]() This app makes you control your Arduino projects like RC car or any IOT applications using your mobile phone thru bluetooth.Īll the files (apk, circuit, program, codes) are all provided) :) Compatible with android 4.4.4 (API 19) to android 10(API 29). This app is for those who has two types of bluetooth module and dont want to download each app specifically for that BT module. So i made this app to circumvent those problems whehe. ![]() So there's a lot of arduino bluetooth controller in googlestore(play store) but there's limited buttons, functions and also limited to hc05 only or hm10 only. Ok why plus ultra? cuz im a big fan of all might(Plus ultra means go beyond your limit).
