Hello everyone! In this artical i will try to update my older artical about RF ASK 315MHz and 433MHz,with more application and update the library i used before First it might be good to check my older artical about with many feedback arrived me about it, i decided to fix many issue like: • Using Library, more better and a comprehensive library.• Using a module from Seeedstudio comes with antenna to see if it will increase the range of Tx and Rx.• add more codes and video for this RF. Let's start with component we need. • Arduino Board x 2 pcs 'You can choose any 2 board type you want I used Uno and Nano to do this experiment.• RF315/433 module, You can buy it from I used This one • Breadboard• Jumper wire• if you choosed seeedstudio grove module, with them too• Power source'you can use power bank or 9V battery or even your PC usb port, it's up to you You need to have an arduino IDE, you can. IMPORTANT CHANGE to interrupt pins on Arduino with RH_RF22 and RH_RF69 constructors: previously, you had to specify the interrupt number not the interrupt pin. Updated documentation with respect to transmitter power control for RFM23 Fixed a problem with RH_RF22 driver, where GPIO. I tested it on arduino 1.5.2, 1.5.5 and newer 1.6.9 and worked well on them all. ![]() If you looking for upgrade the way you want to control RF module by,you can send a command from serial monitor. No need to change the receiver code, all you need is to upload this code to transmitter arduino board and open a serial monitor set the buad rate to 19200 Send X character to turn on the LED on the receiver Send Y character to turn on the LED on the receiver You can design an application on PC or MAC with interface to control this module for more advance project. Finally: I powered my circuits from power bank to test the maximum range of this module. Actually it was not that much of improvement as i expected,even with antenna the range in open area was around 44 meter, and inside my home it was about 20m max. I noticed something from my experience: • the range will be less if you put the Tx and Rx near WiFi router.• the range will be less if you put the Tx and Rx near electricity transmission line 'High voltage'.• if you touch the antenna the data might be lost• the range will be less if you put the Tx and Rx near Microwave oven.• the Transmitter will be more better if you install it on higher level 'altitude'than the receiver hope to hear your questions and suggestions about this artical in the comment below or on Attachments •. Hello Mohannad I need some help to work out what arduino requirments I need for the following. I have designed a machine a in my home workshop that I now want to add an RF transmitter and RF receiver to, thereby controlling the machine by remote radio control. The machine in it's present form is controlled by the user pressing either one of two single axis joysticks that power each individual 24v dc motor thereby driving a single wheel. So I've designed a remote control box using the same joysticks ( there are 2 joysticks used on the remote ) and all I need is someone to describe the type of reliable RF transmitter and RF receiver and associated parts that I need to add to the machine to convert from user controlled to radio remote control.
