To check the working of the transmitter, it is necessary to down-convert the 40kHz signal into 4kHz to bring it in the audible range. On these pages, I will introduce Remote Controller with Radio Frequency. Below you will find a diagram for the RC transmitter and the receiver circuit and also the coding for each of them. 50 meters closed area is working smoothly. For instance you could have 2 bomb drops, or 1 bomb drop and a set of lights. PT2262 used as Encoder (Transmitter) and PT2272-M4 Decoder (Receiver) ICs are heart of the project. You may also like RF remote control with 4 channels. FREE Shipping by Amazon. 8 Channel RF Remote Control - This is an 8 Channel RF Remote Transmitter and Receiver that will allow to remotely control various electronic projects. Now slowly make distance between the transmitter and the receiver and adjust the trimmer at both sides. If you don’t have the NRF24 library, go to Arduino IDE and go sketch > include library > manage libraries. if(MSFPhover) { MSFPnav2n=MSFPpreload("_derived/up_cmp_radius010_vbtn.gif"); MSFPnav2h=MSFPpreload("_derived/up_cmp_radius010_vbtn_a.gif"); } Here is a hobby circuit of a multi channel remote control system, by which you can control 8 different appliances. RF Remote Control provides 2 latched and 6 momentary outputs that could be used to control your favorite devices such as amplifier, robotic devices, RC cars, computer, home appliances, lamps and many other cool gadgets. amzn_assoc_search_bar_position = "bottom"; Both the RF transmitter and receiver circuits need separate power supplies. resistor R1. As you can see the RF Transmitter Circuit consists of the Encoder IC and RF Receiver circuit consists of the Decoder IC. Depending on the supply voltage, // -->
