Parallax 29122 IR Remote Parts Kit
The Parallax 29122 IR Remote Parts Kit is a comprehensive component assembly designed for building infrared remote control systems and receiver modules in embedded applications. Electronics engineers, robotics developers, and hobbyists use this kit to rapidly prototype wireless control interfaces for microcontroller-based projects without designing complex IR circuits from scratch. This kit solves the challenge of integrating reliable infrared communication into projects by providing pre-selected, tested components that work seamlessly with Parallax microcontrollers and standard Arduino platforms.
Product Overview
The Parallax 29122 IR Remote Parts Kit contains all essential components needed to construct functional infrared remote transmitter and receiver circuits. The kit operates on the principle of modulated infrared light transmission, where data is encoded as pulses of 38 kHz carrier frequency IR light. When the transmitter sends signals, an IR LED emits modulated light that travels through air and reflects off surfaces, allowing wireless communication across typical room distances of 5-10 meters. The receiver circuit uses a photodiode paired with a dedicated IR demodulator IC that filters ambient light noise and recovers the original digital signal, ensuring reliable communication even in bright environments.
What distinguishes the Parallax 29122 kit is its integration with Parallax's ecosystem of microcontrollers and its compatibility with standard NEC and RC5 IR protocols commonly used in consumer electronics. The component selection ensures minimal external circuitry requirements, making it ideal for rapid prototyping and educational applications. Each component is tested for compatibility, and the kit includes detailed schematics and code examples for popular platforms. The standardized 38 kHz carrier frequency allows interoperability with commercial IR remote controls, enabling students and engineers to create projects that respond to standard TV remote commands or build custom remote control systems.

How to Use
Begin by identifying the kit components against the included bill of materials: locate the IR LED (typically red or clear with infrared emission), the photodiode receiver (small black component), the IR demodulator IC (usually a 3 or 4-pin package like TSOP1738), and the supporting resistors and capacitors. For the transmitter circuit, connect the IR LED through a current-limiting resistor (typically 220-330 ohms) to your microcontroller's output pin, with the cathode grounded. The receiver circuit requires connecting the photodiode to the demodulator IC input, with the IC output connected to a microcontroller input pin configured for digital signal reading. Ensure proper orientation of polarized components, particularly the IR LED and photodiode, as reversed polarity will prevent functionality.
After assembling the circuits on a breadboard or PCB, load the provided example code into your BASIC Stamp or Arduino platform. The code typically initializes the input pin to detect IR pulses and decodes the received signal according to NEC or RC5 protocol standards. Test the transmitter by pointing it at the receiver from various distances and angles, starting at 1 meter and gradually increasing range to verify the 5-10 meter operational envelope. Use a smartphone camera's night vision mode to visually confirm IR LED emission, as human eyes cannot see infrared light. Calibrate the receiver sensitivity if needed by adjusting component values according to the schematic provided, particularly if operating in high ambient light conditions.
Frequently Asked Questions
Can I use the Parallax 29122 kit with commercial TV remotes?
Yes, the kit's 38 kHz carrier frequency and NEC protocol support make it fully compatible with standard TV remote controls. You can build a receiver circuit that decodes signals from any commercial IR remote using the standard NEC protocol. This enables projects where users control microcontroller-based systems using existing household remotes without requiring a custom transmitter circuit.
What is the maximum transmission range for this IR kit?
The typical transmission range is 5-10 meters in normal indoor lighting conditions with direct line-of-sight between transmitter and receiver. Range can be extended by using higher-brightness IR LEDs or multiple LEDs in parallel, though the kit components are optimized for standard 5-10 meter applications. Ambient light, particularly direct sunlight, reduces effective range, while reflective surfaces can extend it through indirect signal paths.
Do I need additional components beyond what is in the kit?
The kit contains all essential components for basic IR transmitter and receiver circuits. However, you will need a microcontroller (BASIC Stamp, Arduino, or compatible), power supply (5V DC), breadboard or PCB for assembly, and connecting wires. Some applications may require additional protective components like diodes or filtering capacitors depending on your specific circuit design and electromagnetic environment.
Is the Parallax 29122 kit suitable for beginners?
Yes, the kit is specifically designed for educational use and includes detailed documentation with schematic diagrams and sample code. The through-hole component design is ideal for breadboard prototyping without soldering. Beginners should follow the provided schematics carefully, verify component orientation before powering the circuit, and start with the example code before customizing for specific applications.
