What does MHz mean in remote control cars?

What does MHz mean in remote control cars?

The term “MHz” is the abbreviation of “megahertz,” or one million cycles per second. It is usually used with ready to run models, because it is legal for RC use in most countries for all types of RC models as it is used as the so-called citizen’s band.

Which IC is used in remote control car?

The TX-2B/RX-2B is a pair of CMOS LSIs designed for remote controlled car applications. The TX-2B/RX-2B has five control keys for controlling the motions (i.e. forward, backward, rightward, leftward and the turbo function) of the remote controlled car.

What is 49 MHz mph?

10 MPH
49 MHz – Speeds up to 10 MPH.

What makes a remote control car work?

Once the RC toy receives the radio waves, the motors kick into life to cause a specific action to occur. The power source sends power to all working parts, including the motor. The transmitter enables control through radio waves and the receiver activates the motors.

What is tx-2b 5 channel radio remote control?

TX-2B / RX / 2B 5 channel radio remote control. This article is about a simple 5 channel radio remote control circuit based on ICs TX-2B and RX-2B from Silan Semiconductors. TX-2B / RX-2B is a remote encoder decoder pair that can be used for remote control applications.

What are the features of tx-2b/rx-2b?

TX-2B / RX-2B has five channels, wide operating voltage range (from 1.5V to 5V), low stand by current (around 10uA), low operating current (2mA), auto power off function and requires few external components. The TX-2B / RX-2B was originally designed for remote toy car applications, but they can be used for any kind of remote switching application.

How does the tx-2b push button switch work?

These push button switches are interfaced to the built-in latch circuitry of the TX-2B. Resistor R7 sets the frequency of the TX-2B’s internal oscillator. Resistor R1 and Zener diode D1 forms a simple Zener regulator circuit for providing the IC with 3V from the 9V main supply.

What is the function of the R7 resistor on the tx-2b?

Resistor R7 sets the frequency of the TX-2B’s internal oscillator. Resistor R1 and Zener diode D1 forms a simple Zener regulator circuit for providing the IC with 3V from the 9V main supply. C2 is the filter capacitor while C1 is a noise by-pass capacitor.
