Rc helicopter remote control circuit diagram pdf

2B  5 channel radio remote control. This article is rc helicopter remote control circuit diagram pdf a simple 5 channel radio remote control circuit based on ICs TX-2B and RX-2B from Silan Semiconductors.

Remote Control Circuit Through Radio Frequency Without Microcontroller Description This is a simple type remote control by using RF communication without microcontroller. In this project a remote has been designed for various home appliances like television, fan, lights, etc. These devices are designed to provide a high level of security and operates from anything between 2 to 6.

The circuit given below is of a telephone operated DTMF remote. The circuit can be used to switch up to 9 devices using the keys 0 to 9 of the telephone. Here is the circuit diagram of simple but highly effective TV remote jammer circuit.

Most of the TV remotes have 38KHz operating frequency. A different type of remote control circuit employing ultrasonic signals is given here. The IC1 is wired as an astable multi vibrator operating at 40KHz.

Here is a versatile remote controlled appliance switch that can ON or OFF any appliance connected to it using a TV remote. IR remote sensor IC TSOP 1738 is used for recieving the signal.

This circuit was designed in response to a request from my reader. What he asked for was a 1KHz IR transmitter circuit for some remote control application. I think this circuit may satisfy him. In application level this circuit is similar to that of the circuit given previously.

The only difference is in the approach. This circuit is designed by using another method. IR to RF converter circuit. The IR to RF transmitter circuit given here can convert the IR signals from your remote to RF signals to long distances.
