Schematic AVR Radio Frequency Keypad

The AVR based RF Keypad is remote controller that emits an RF code every time you digit the correct combination on its keyboard. You can use this project to replaces remote controls based on MM53200, UM3750 and UM86409. There are three different combinations for three different actions can be entered at program-time. The keyboard layout also customizable. You can use any matrix up to 4 rows by 4 columns keyboard layout and assigning your own ASCII codes to each key.

 Besides emits RF, you can use it as serial keyboard to PC (requires a polarity inversion) or Basic Stamps by drop off the RF part. Keypresses are available as ASCII codes at pin 3. AVR RF Keypad is designed by Alberto Ricci Bitti

Schematic RF and IR Remote Control

This PIC based remote control allow you to control up to 8 devices by this easy constructable remote control. The project very flexible you can use it as radio remote control or infrared remote control, depending on the components. Each device output can be configured to be momentary (turned on while you press the button) or latched. Latched outputs can be toggled on/off by one button per channel, or turned on and off by two buttons per channel.

Schematic Smartphone AVR DTMF Remote Control

This project based on Microcontroller AVR ATtiny 2313 and SmartPhone as main part. The project can controls 3 relays by DTMF sounds emitted by a Smartphone. Emilio, the designer, said that this project useful for controlling, for example a rover, using relay as motor power switches.

The Smartphone (with Windows Mobile 6 OS) can run as web server with capture ability and send the picture to the client via internet. Other features of this circuit is the Smartphone can also moved and controlling motors with his speaker, emitting the correct dial tones in relation to GET requests from internet client. It's not necessary to make any connection from the phone to the circuit, because the phone connects "wireless" using the sound.

You can download test program written for smartphone WM6, schematic, and hex file here

Schematic Arduino Autopilot Control

ArduPilot is a full-featured autopilot based on the Arduino open-source hardware platform. It is a custom PCB with an embedded processor (ATMega168) combined with circuitry to switch between RC control and autopilot control (that's the multiplexer/failsafe, otherwise known as a "MUX"). This controls navigation (following GPS waypoints) and altitude by controlling the rudder and throttle. These components are all open source. This autopilot is fully programmable and can have any number of GPS waypoints (including altitude) and It uses infrared (thermopile) sensors for stabilization and GPS for navigation.

Schematic AVR Nikon Camera Remote Control

This is an IR remote control for Nikon cameras. The circuit project is very simple: an ATtiny13V, button, transistor, resistor, IR diode and 3V battery. You can also connect the IR diode directly to the ATtiny13V, but that will limit the LED current and therefore the range. The project is compatible with the Nikon ML-L3 remote control. Supported cameras include: D40, D40X, D50, D60, D70, D70s, D80, and Coolpix 8400 8800. This project created by Dick Streefland

Schematic RC Pulse to PWM Converter Project

This Project describes an AVR chip and software that converts two easily formed R/C pulse signals and converts them into a PWM signal suit for driving small motors. This will be good solution for common problem for hobby robotics when controlling the drive level to a motor. As many hacked R/C servo's are used have poor control range. And many micro-controllers don't have built in PWM or the PWM is very slow and makes for lots of motor buzz.

The value of this AVR software application is that one can interface the output signals of the AVR chip to a wide variety of H-Bridge driver chips with a current capacity from 600ma to 5+ amps. Or, it could drive a discrete FET bridge for even higher capacities. The software runs on an Atmel AT90S1200 chip with a 16mhz clock. The project designe by Larry Barello.

Schematic Microcontroller Based Remote Sensing System

PageAlert is a flexible remote sensing platform connected to a data recording and alarm system. It is based on an MC13192 SARD board. This electronic project well designed by William Wittig. An MPXM2010 pressure sensor effectively senses the water level in a sump pump hole. The limited transmission range of ZigBee technology makes this wireless system ideal for home use.
