* So far, I use library "SoftwareSerial.h", but later it will be changed 😀 Arduino nano/pro mini sketch for remote: /* Currently I am using it as a remote for my car and my “weirdo-boat”, which didn’t touch water (yet), except some bath water. Note that this is just beta version, which means that it has just essential functions, not fully developed and just for sake of testing, and showing how it works. Yes, here are my first working codes for Arduino nano and Arduino pro mini (Although it may work with other versions too). (I started to work on Si4432 and Si4463 alone, but it is not so easy to understand how it really works, an modules has pin raster of just 1.27 mm, so not easy to manipulate…) Some codes? So, someone made HC-12 module, which has “as-is” functions. This is because this module has MCU for dealing with all needed parameters, while main RF chip inside is Si4463, beautiful chip, yet pretty difficult to make it to work due to lack of documentation. The same is for changing channel, at least 80 mS needed for module to change channel. When sending AT commands for changing parameters, 80 milliseconds needed to module back information whether your command is okay or received in error. Only telemetry is possible for battery status, GPS coordinates and various other things, since it is actually transceiver, not simple transmitter or receiver – both modules on remote and your vehicle or any other apparatus (for example, you want to trigger camera by this remote) are capable to send some data back.Īnother limitation is speed of changing parameters, lack of hopping ability and few others. First at all, this module has no RSSI, so telemetry and feedback about how good signal is at other end is not possible. But, since we need mostly decent speed, say 15 kbps in air, less than 400 kHz will be more appropriate, but this module just has not this option. This “huge” spacings are made because this module can work on really wide modulation on high speeds. Keep in mind that HC-12 has 100 channels, with 400 kHz spacing, which means that channel 100 will be at 437.400 MHz, well above legal limit of 434.790 MHz (from 433.050 MHz to 433.790 MHz, so only first four channels are “legal” by any means. For example, while most of the world accept 100 mW power, in UK is allowed only 1/4 of that: 25 mW maximum. So, no any licence needed, just pay attention of your local regulations. Note that this frequency as well as 2.4 GHz and 5.8 GHz are under ISM bands. All what is currently present on this band is wireless car keys, humidity and temperature sensors, and maybe other unknown low power transmitters. The reason is simple: 2.4 GHz is too much “crowded” with all that WiFi signals and it has more dependence of humidity, obstacles, and other factors. Out there exist up to 1 W transceivers, but this will come later as long range will be needed, just for sake of simplicity, I will say that 100 mW is more than sufficient for decent range.

Transmission range at 12 V: 100 m outdoorsįor the users of Grove (especially beginners) there are instructions in pdf format.Arduino remote is an attempt to use relatively cheap HC-12 module, which has plenty of options, ranging from 100 channels, power setting from 0.8 mW up to 100 mW at 433.4 to 437.4 MHz. Transmission range at 3 V: 40 m outdoors Operating voltage (max.): 12 V DC 10 mA uses ASK (Amplitude Shift Keying) Modulation
The branching configuration of this kit allows a transmission distance of approx. This kit is used for one-way wireless communication with a frequency of 433 MHz and includes a transmitter module and a receiver module.
