Matchless 4 Channel Transmitter And Receiver Circuit Diagram
The relay coil may be 5v then it can run from the same supply as the receiver.
4 channel transmitter and receiver circuit diagram. In the first circuit is the transmitter second is receiver i controlled 3 rgb led by this modules. As you can see the rf transmitter circuit consists of the encoder ic and rf. If you want to use all the channels build the power switching circuit 4 times.
Pt2262 used as encoder transmitter and pt2272 m4 decoder receiver ics are heart of the project. 4 channel rf remote built using pt2262 and pt2272 m4 ic from princeton technology. Similarly i have added 4 dip switches sw2 which will connect to ground and feeds data on activation since the data pins are active low.
220 uf 16v electrolytic cap. Answer 6 years ago reply upvote 1. Below pictures showing the rf transmitter circuit with breadboard setup.
Figure 2 rf 4 channels receiver circuit. Transmitter works with 5v to 12v dc. If the coils need higher voltages such as 12v or 24v relay is powered from the the corresponding voltage supply.
The 4 channel rf receiver and transmitter can be used with or without an arduino. There are 7 pins in the receiver module. Gnd this should be connected to ve terminal of a 5v battery or gnd pin of arduino.
All outputs are ttl level can be interface with other circuits or relay board. You can connect relays to the receiver outputs to control it wirelessly. Can i make 2 channel radio transmitter and receiver easlly if yes any circuit diagram.
