Range around 80m in open field , 30-50 indooryou can program multi-receivers to send a data to one transmitter and the transmitter can recognize them depends on the message they sent to it(for example Rx #1 send a data starting with "A" character , Rx #2 send a data starting with "B" character and so on ).note: this module not for streaming - transfer data , just use it to send short messages "signals" and you need to check your country/region regulation for that.

actually nothing ! just upload the tx code to both tx circuit and change the character you want to send from each tx , so at least the rx will know from which tx the message came from.

because in my case I ran the motor without load connected to the shaft so it will need a few milli amps to works if you want to connect an external load to the shaft so you need to use external power supply

no , in this way if you enable the pins you , PWM is equal to pwm pins so it will not work you can connect pne PWM pin to GND or VCC and connect the other to PWM pin in your board , so once you enable the driver you can control the speed of the motor using PWM .

after you upload your code , you must see the motor rotating 360 degree and will do forever , if you open the serial terminal you can see the time and a word (wait!) .to make a motor rotate for half a cycle , just go to a variable called (steps_left) and change it , you will find it on the beginning and in the end of void loop

for Nintendo Nunchuk Controller I don't know how it works "i don't have one either " but for other Joystick (for example like this : https://goo.gl/xQH5hi or this https://goo.gl/iqp5AN ) the joystick has x and y axis and give you 2 analouge signal for each axis , after that you can use your arduino board to see the voltage value for each axis .now how do you want to control the car ? wireless ? like bluetooth or wifi or RF ?

hello there! don't worry about that ,you can ask whenever you want.you can achieve that in many way, simply you can adjust the buad rate for each pair with different value (ex first pair 3500 , second pair 3600 ..so on) this good for a few number of pairsthe other way is to set each tx to send a unique signal (ex: first pair send : $14 , second pair send &17) and the receiver will only respond to his tx signal

Unfortunatley I didn't have now a new smartphone(still stick with my old S4) but even S4 with BLT 4.0 works fine with HC05 , HC06 as well You can use newer Bluetooth module like CC2540/CC2541 , support 4.0 BLT and work with Iphone and android as well

Appreciate your comment :) thank you so much I will also update the library link.
- Mohannad Rawashdeh commented on Mohannad Rawashdeh's instructable Digital Potentiometer MCP41100 and Arduino
PWM(Pulse width modulation) is a method(Technique) to control a DC Voltage , and you can achieve that in different ways(like using Transistor).In my video , you can see that I connected MCP41100 to 555 timer which act as a PWM controller , MCP41100 connected to the control side not to the High power side(you can see the schematic for more details).hope that's clear for you , and if you have another question I will be happy to answer it
View Instructable »no it will not work on this way , this potentiometer can works with Low power application , if you connect it directly to LED strip it will blow up for sure .try using PWM using Mosfet / Fet transistor to control Led strip brightness (that's what you want to do , right ?)

on teensy 3.1 / 3.2 you need to use Digital Pins with serial 1 (D0,D1) ,serial 1 (D9,D10) OR serial 3 (D7,D8) and use the hardware serial serial , which is easier and have more capability than software serial

For the first stage , yes you can do it and all you need to do is check the receiver frequency and the data rate (speed) in Bit per second , you need to follow (try and error ) method until you can receive the RF message for the second stage , you want to remove the RF Rx and replace it with arduino , well if you can finish stage 1 ,this one will be much easier.

Hey Humzal , thank you for your comment because this type of of RF we don't have an address system which allow to us to setup a network or do a simple (one Transmitter and multi receiver system) here some tips to how to do a multi tx and multi Rx network "this method is an experimental one , and from my own experience only)1- if you want to build a single Tx and Multi receiver you need to set the speed from ( vw_setup(uint16_t speed)) to be similar for each other devices ** send a message contains at least 2 bytes ( for example X1 ) the receiver must be programmed to read the first char as a Target device , so if the receiver name is X that's mean this message to this receiver , otherwise ignore it ( do this using if statement and read the char name[0] to do the comparison )i worked…

well theoretically you can, this module designed to send a signal not a data , you need to work a little bit on the code side to change the servo angle to character string and then send it .

for your project , you can use this RF , connect the joystick to Tx and you need to read the joystick axis voltage and on the receiver side you need MCU+RF receiver and if you want to control the motor on/off , use the realy , otherwise if you want to control the speed of the motor , you need a motor driver , something like this https://goo.gl/SNqub3

Yes you can , for floating point you can get any frequency you want.but from my experience , don't use potentiometer to read the frequency with floating point , sometimes the frequency is +-0.2MHz , use push button to set the frequency .

after you re-power on the module remove EN pin from Vcc and keep it unconnected to enter AT mode .did you try different buad rate ? sometimes it's 9600 another time 38400

EN pin is connected to wakeup pin in HC05 , you need to connect Key pin to VCC and then power off the VCC and re-power it again to enter to AT mode.after you enter to AT mode you can disconnect this pin , no need to connect it to GND .open serial monitor and set the serial option "both NL & CR" not no new line"
- Mohannad Rawashdeh commented on Mohannad Rawashdeh's instructable Arduino AND Bluetooth HC-05 Connecting Easily
the problem in the bluetooth it self.can you just power on the bluetooth alone and check the led status
you need to set HC05 as a slave so your phone can pair with it , otherwise it will not see it.
you need to power off the module and then power it on again

my pleasure for the receiver i thinks you can change the pin using:RH_ASK (uint16_t speed=2000, uint8_t rxPin=11, uint8_t txPin=12, uint8_t pttPin=10, bool pttInverted=false)so inside it you can set the speed and tx , rx pin as well

what is your arduino version ? in the newer Arduino IDE this library is not working well .please check my newer article about this RF using radio head libraryhttps://www.instructables.com/RF-315MHz433MHz-W...for nrf yes it's way better than this module ,but 10Km is not availabe in this module, the communication regulation in most of the country the nRF power<60mW and as a range about 2KM .

first you need to set all the transmitter and receiver with the same bit per secondusing this commandvw_setup(uint16_t speed);second,you need to write your code and just change the character you want to send from the transmitter. this module can't work alone without mcu so you need, no shift register required in this case , and you can set each receiver to read a specific data "by change the if statement in your code".
