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…

Introduction Of The Over The Air Update (OTA Update) This article discusses about how to update a microcontroller’s program/chip firmware over the air (OTA Update). With increasing the source code lines and the firmware/program size, probability of errors will increase. So the application of OTA update is usually in smart circuits with larger firmware size.…

In the ESP8266 WiFi Module article, I introduced the ESP8266 module and a sample circuit with this module and ATmega8a which is called WiCard. The WiCard WiFi Module Description The WiCard WiFi module has two cores, one of the cores controls WiFi connections between the module and server/user application. Also this core parses the user program…
