My first two projects related to Arduino are clock related. If you haven’t seen them before, its the Digital Alarm Clock and Digital Clock on 7 Segment Display. Now, I am going to share a project which uses Cheap RF Modules to control robot wireless.
The wireless transmission uses cheap RF module on 433Mhz. This modules can be obtained at a very low cost. Since they are available at low cost, they are not that perfect as compared to more expensive RF modules. Continue reading “RF Controlled Robot Car”
If you haven’t check on the first part on RF module explanation, you might want to read it before proceed with RF using library. Here we going to discuss how to implement VirtualWire library with low cost RF module. VirtualWire library does not use the Arduino UART pin (digital pin 0 and digital pin 1).
You can download the VirtualWire library here.
Before we look into the code, let us see some of the functions.

Ever wonder how to implement wireless control on your project without spending too much of money? It is possible with cheap radio frequency (RF) module, consists of transmitter (Tx) and receiver (Rx). The RF module has to be used in pairs which are of the same frequency. Frequency of low cost RF module available are 315MHz and 433MHz.
