4 channel RS485 Remote Controller

4 Channel 2 core twisted pair remote controller built using PT2262, PT2272-M4 IC from Princeton technology and MAX485 IC from Maxim. PT2262 is an Encoder (Transmitter), PT2272-M4 Decoder (Receiver) and MAX485 works as bridge for twisted pair communication between encoder and decoder. The receiver provides 4 channel Momentary outputs. All outputs are TTL level and can be interfaced with other circuits or relay board. Transmitter works with 5V to 12V DC. Receiver works with 5V DC.

When any of SW1-SW4 (S1-S4) tact switches is pressed, power is applied to encoder IC and RS485 IC, the encoder starts scanning Jumper J1-J8 and transmitting the status of the 8 bits address and data serially. The decoder IC receives the data from MAX485 and compares it two times with J1-J8 address jumpers, also provides outputs high and at same time VT (Valid Transmission) LED goes On, if the data is Valid and address of Transmitter and Receiver are same. It is important to have same jumper settings J1-J8 at transmitter and receiver to pair both.

6 Channel RF Remote Controller Using CC2500 RF Modules

The 6 Channel RF Remote Controller designed using CC2500 RF Transceiver modules and PIC16F1847 micro-controller from microchip. Transmitter provided with 6 tact switch, 4 Address Jumpers to pair multiple unit so they don’t interfere with each other. Board provided with power LED, valid transmission LED. Project works with 5 V DC, On board LM1117-3.3V regulator for CC2500 Module.  Two in one PCB can be used as Transmitter & Receiver.

Receiver works with 5V DC. 4 Jumper to paring RX& TX units, valid signal LED, power LED, and 9 Pin connector for outputs.  Same PCB is used as transmitter and receiver.  All outputs are Latch Type and TTL 5V Signal for easy interface with other devices like Relay Boards, Solid State Relays.

SMART.IO, An Affordable Remote Control for Embedded Designs

Creating a smartphone application for your embedded products may be a high-cost process that consumes time and efforts. ImageCraft, a producer of high quality low cost embedded system tools, had developed “Smatr.IO” as a very cheap alternative solution that allows you to add a friendly user interface to any embedded project.

Smart.IO is a toolkit that helps you to create a compatible application with your product without the need of any experience in wireless technology or app development. It uses BLE (Bluetooth Low Energy) and it doesn’t require an Internet connection or data plan.

Smart.IO consists of three parts:

  • A Small Chip Module compatible with any microcontroller.
  • A Software API for creating Graphical User Interface (GUI) objects.
  • A Programmable Smartphone App that requires only a Bluetooth connection to use.

There is no need to write any wireless code, or write an app. All you need is to add the Smart.IO chip to your existing microcontroller-based design, then use the API to create GUI objects in your firmware.

The Smart.IO Chip Module

The Smart.IO chip module is only 25mmx14mm. It has a 10-pin headers which are easy to solder onto your PCB, or use in a prototype system. It interfaces with your host microcontroller using SPI pins, plus extra pins for interrupts for data notification. Smart.IO draws very little power, typically about 100mA, and much less during standby mode.

If you are an Arduino user, ImageCraft will provide an Arduino-compatible shield that comes with a Smart.IO chip module, so that Arduino users can start using it immediately.

The Smart.IO API

The API functions allow you to create GUI objects and to modify their values. A simple callback mechanism notifies your firmware of input changes. The API code will run in the Smart.IO chip firmware, and the host MCU only runs the API interface layer code, so it will not use the host MCU resources.

The Programmable Smart.IO App

The GUI elements incorporate solid, current user interface principles. The UI will look and work exactly the same way across all iOS devices, from the iPhone 5 to iPhone 7+, and all iPad devices, including the iPad Pro. An Android friendly UI is planned for Spring.

There is also a customized version of the app specific to your product and branding for an inexpensive one-time licensing fee including customized app logo and name and security key to ensure your product will only work with your app.

Smart.IO Security

Secret key encryption is used to ensure secure pairing of the device and customized app. As Smart.IO does not use the Internet, there is no risk of your device being used for DDOS or other types of attacks through the use of Smart.IO.

Through the Kickstarter campaign, Smart.IO reached about $9,500 and pre-ordering is still open here. ImageCraft will start work on the Android version of the programmable app and set up a forum for Smart.IO users. A use case example of Smart.IO is available on the official page.

Arduino Remote Control Tutorial

arduino-remote-control-1024x801

Øyvind Nydal Dahl show us how to use an IR remote control with Arduino. For this purpose he connects a TSOP312 and an IR LED to Arduino and goes in detail on the sketches.

In this tutorial I am going to show you exactly how to make an Arduino remote control. You can use this project to combine functions from different remote controls and make your super-awesome dream remote control!
