The IR receivers typically work in 37 KHz frequency. The “8 Channels Infrared Receiver” project receives the IR signal via HS0038A2 (or similar modules), which the module filters the 37 KHz signal and sends the data in 1 Kbps speed to the ArduinoUNO board. The Project’s Download Link: Infrared Receiver Source Code For Arduino UNO…

The high voltage (parallel) programming method which has been used in WiCardKit Software programmer is the highest layer of access to the microcontroller memories and programming. This method can unlock the AVR/PIC chips which can’t be programmed by regular programmers while the chips work well. The other feature is the “reset” pin in some the…
