Infrared remote controllers are everywhere around us. The majority of home appliances are controlled using infrared remote controls. In this article/video, we learn to build a device that can decode (almost) any IR remote control and use the instructions to switch the relays (loads). So we can use this feature in a variety of applications without buying a new IR remote control and expensive hardware, such as turning ON/OFF the lights, opening/closing the curtains, ... etc. I have used an ATTiny85 microcontroller as the heart of the circuit. The device can record up to three IR codes in the EEPROM memory and switch 3 separate devices. Each relay can handle the currents up to 10A. The load switching mechanism (momentary ON/OFF, toggling, .. etc) can be programmed by the user. I used Altium Designer 21.4.1 and the SamacSys component libraries (SamacSys Altium Plugin) to design the Schematic and PCB. I also used the Siglent SDS2102X Plus/SDS1104X-E to analyze the IR signals. The device works stable and reacts well to the transmitted IR signals. So let’s get started and build this puppy!

Features High stability and no sensitivity to the ambient light Laser-cut acrylic (plexiglass) enclosure Cost-effective Flow control capability of the hand-sanitizer/alcohol (efficiency) Through-hole components (easy to solder) Single-layer PCB board (easy to fabricate) Single and cheap ATTiny13 microcontroller Low standby current consumption As we all know, the COVID-19 outbreak hit the world and changed our lifestyle. In this condition, alcohol and hand sanitizers are vital, expensive, and in some areas hard to find fluids, so, they must be used properly and efficiently. In the second version of the hand sanitizer dispenser device, I have addressed the previous design problems and introduced a device with no sensitivity to the ambient light and flow control capability of the alcohol/sanitizer. Therefore just enough amount of liquid will be poured on each request. The design uses a cheap ATTiny13 microcontroller.

Hello.Looking for information on the fastest arduino infrared temperature sensor.If there are sensors out there that can sense between 100 and 300 ms,sensors don't have to be arduino,but there must be ready made interface boards and compatible software.Any assistance will be greatly appreciated. Thank you Regards Arthur
infrared signal is used as the "trigger" for the operation of dc motors(or any other appropriate devices eg:LEDs). i have used the arduino uno as the microcontroller as it simply does the job!also it's cheap too!! future application will ultimately lead to IR controlled robot,and perhaps controlling of human mind using nothing but a simple remote control and interfacing hardware with electrodes,so that the physically disabled can attain normal "motor" functions.thanks.
