Infrared (IR) Proximity Detector
This is an infrared (IR) proximity detector circuit. A matched infrared emitter and detector pair is utilized in this circuit. The voltage-controlled oscillator (VCO) section of the LM567 tone detector integrated circuit (IC) is employed to set the emitter LED...
Simple Infra-Red Transmitter/reciever Shematics
This 1 channel infrared transmitter/receiver remote control is the cheapest and simplest you can find. The transmitter transmits a sequence of pulses on 36 KHz frequency carrier. The diodes are Schottky type because of their low voltage drop (only 0.2V)....
Four channels infrared remote controller circuit diagram
The receiving circuit involves an infrared signal being input to the MC3373 from pin 7 via a phototube. The amplified signal is output from pin 1 and sent to pin 12 of the decoder 8802. When the transmitter F is...
DIY Infrared Sensor Module using Arduino
Have you ever wanted to create a line-following robot but found infrared sensors too expensive? If you are located in the UK and have access to a Maplin store nearby, you can purchase infrared transmitters and receivers for just 99p....
infrared remote control tester
While developing an infrared (IR) extender circuit, a method was needed to measure the relative intensities of various infrared light sources. This circuit is the outcome of that research. A photodiode, specifically the SFH2030, is utilized as the infrared sensor....
Infrared Fire-Cracker Igniter
Firecrackers are typically ignited using a matchstick or candle. It is necessary to retreat quickly after lighting the fuse of the firecracker, which poses a safety risk due to the potential for the firecracker to explode before reaching a safe...
Infrared transmitter
The ultra-simple one-transistor IR transmitter is designed to transmit sound from any 8 or 16-ohm audio source, such as a TV, radio, or tape recorder, using an infrared beam of light.
The one-transistor infrared (IR) transmitter circuit operates by modulating the...
Infrared Remote Receiver Has Four Outputs
This circuit allows any infrared (IR) remote control to manage the outputs of a 4017 decade counter. It utilizes a 3-terminal IR receiver (IRD1) to capture infrared signals from the transmitter. The output from IRD1 is connected to an NPN...
Glue stck torch
This project, developed around 2005, involves constructing a torch using a glue stick, which conveniently accommodates an AA battery within its plastic casing. To create a functional battery holder, contacts for both the positive and negative connections are necessary. The...
