Making a Remote Controlled Car using Sun SPOT
A remote Sun SPOT will transmit data to a Sun SPOT mounted on a car, which will control an integrated circuit (IC) according to the digital input/output pins D0 to D3. The IC will subsequently drive the motors that propel...
Simple IR Remote Tester
Most cases of infrared remote control failure can be identified by the absence of the pulsed transmitted infrared light. It is very rare that the...
Infrared remote controls operate by transmitting modulated infrared light signals that are detected by a corresponding...
TX05C-R infrared surveillance alarm circuit
The TX05C-R infrared surveillance alarm circuit is designed for monitoring walls, windows, doors, and various restricted areas. When an intrusion occurs, the alarm activates to enhance security. The circuit comprises a transmitter module, a receiver module, a time-base circuit, a...
ir remote circuit
A series of emails have been received requesting schematics for infrared remotes. This document presents a schematic for such a remote, which transmits a tone using an infrared LED. The tone is decoded by the receiver, ensuring that the receiver...
Robot eyes
An infrared LED and a phototransistor are utilized for each eye. Half of a 556 timer IC (IC1-a) operates as an astable multivibrator oscillating at a frequency of approximately 1 kHz. This IC drives transistor Q1, which subsequently controls two...
200 meters remote control schematic design
Early transmitters using LC oscillators experience significant frequency drift. The introduction of Surface Acoustic Wave (SAW) devices addresses this issue, providing substantial frequency stability comparable to crystals. These devices can achieve fundamental frequencies in the hundreds of megahertz or even...
IR remote control dimmer light circuit diagram
This is an infrared emission circuit diagram. The NE555 circuit generates a 40 kHz pulse, which is sent by the infrared emission control SE303 after being amplified by VT. The remote receiver and infrared dimming circuit are composed of the...
Reflected Infrared Light Switch
Infrared light reflected off a finger is used to activate this switch circuit.
This circuit utilizes infrared (IR) light to detect the presence of a finger, allowing for a touchless activation mechanism. The core component of this circuit is an infrared...
