    RF 434Mhz Multiple transmitter and single receiver

    yes it will work fine. :)

    RF 434Mhz Multiple transmitter and single receiver

    You cannot solve that problem, since both work on the same frequency, frequency jamming cannot be avoided. You need to write a program that the transmitters are alternatively on

    5v to 230 V relay for a tubelight stalling atmega8

    if I have to overcome this problem, what can I do? I tried on more experiment. I was doing wireless communication between two microcontrollers right below the tube light and I switched it on and off number of times. But the controllers were still working fine. is there any possibility that...

    5v to 230 V relay for a tubelight stalling atmega8

    My tube light is on the ceiling and the switch board with the arduino and relays is 5M away. But I will still try blocking the atmega 8 with a metal case. I tried. But it did not solve my problem.

    5v to 230 V relay for a tubelight stalling atmega8

    Hi, Recently I build a project to control the devices at my home using an IR Remote (RC5 protocol and TSOP) I used a 230V spst relay with a 5v coil. I connected the coil to the controller data pin through ULN2003a. I was successfully able to switch on and off all the devices (Fan, bulb...

    one tx pin to many Microcontrollers

    Hi, I have a GSM modem which gives data in serial. Can I connect the Tx and Rx pins of the modem to 6 different micro controllers directly?

    RF Remote TX/RX issue - need a little help understanding

    Hi, you mean to say that I cannot use two RF transmitters of the same frequency at the same time?

    RF 434Mhz Multiple transmitter and single receiver

    could you help out with the project concept. The project is there will be a transmitter on each person. and the receiver will be with the manager. whenever a person comes in to the office, the respective led will glow. if he goes out, the respective led will be off. PS: yes, RFID is an option...

    RF 434Mhz Multiple transmitter and single receiver

    But unfortunately, In my case all the transmitters will be on. Any solution for this will be really appreciated. My doubt is, what is the point in having address switches on HT1E and HT12D

    RF 434Mhz Multiple transmitter and single receiver

    Hi, I am working on 434Mhz RF modules along with HT12E and HT12D. I have two transmitter and one receiver. The two transmitters A and B have different address on them but work on the same frequency When the receiver address is set to transmitter A, it receives proper data from transmitter A...
