Wireless Messenger

We will start by making an instant wireless messenger.

Copy the content from the file “HC-12 messenger send/receive.txt” in the ZIP archive and paste it to each of the Arduino instances. The code is the same for both Arduinos.

This bundled kit includes both the transmitter and receiver, helping you avoid the expense of buying multiple devices to accomplish one task. Ultimate Convenience. This wireless extender kit uses Wi-Fi to transmit a high-definition 1080p HDMI signal, as well as an IR signal for controlling your source device remotely. IOGEAR's Wireless HDMI Transmitter and Receiver Kit is the perfect solution for the home, office or school environment. It sends uncompressed Full HD 1080p with 3D support from your laptop, computer, game console and / or other HDMI devices. RF 315/433 MHz Transmitter-receiver Module and Arduino: Hi every body, I searched on Instructables about a simple RF Transmitter-receiver module, Which is used in Remote control for cars, or to control simple tasks, like control relay on/off unfortunately I didn't find What I need, So i decided.

After uploading the code, open the serial monitor for both instances.

Now start typing in both serial monitors to start a chat.

Even your Arduinos are connected to the same computer, the communication is wireless.

Toggle Button

A toggle button is used often in electronics. The principle is very simple. You press a button once to turn on the LED and press the same button again to turn of the LED.

Copy and paste the content of the “HC-12 Toggle Button Send.txt” to the “HC-12 sender” instance and the the “HC-12 Toggle Button Receive.txt” to the “HC-12 receiver” instance and upload.

When you push the button, you should see the LED light up. When you push the button again, the LED turns off.

A few validators like timing and button code are used in order to make sure this example works perfect.

Momentary Button

A momentary button is pretty straightforward. While pushing the button, the LED lights up. When releasing the button, the LED turns off.

Wireless Transmitter Receiver For Tv

Copy and paste the content of the “HC-12 Momentary Button Send.txt” to the “HC-12 sender” instance and the the “HC-12 Momentary Button Receive.txt” to the “HC-12 receiver” instance and upload. Point facture serial cracks.

Some useful functions and operators

Wireless Transmitter Receiver Audio

There are a few useful functions and operators that come in handy when you want to convert or spit a string and convert it to a decimal and so on.

Wireless Video Transmitter Receiver

Look at the file “HC-12 Useful Functions and Operators Send.txt” and “ HC-12 Useful Functions and Operators Receive.txt”.

The send sketch sends the string “test123” on button press.

The receive sketch reads the string, split it and convert it to an integer.
