I recently have updated “ESP WiFi Microphone” project to rev 1.3 and now the revision 1.4 is available which is stronger and more stable than rev 1.3. This project is compatible with both of ESP8266 and ESP32 modules and you can simply upload it on NodeMCU, ESP32 DEVKIT and other similar boards. In the latest…

The “DOIT ESP32 DEVKIT V1” module has multiple ACD pins which work in range of 0V to 3.3V with 12 bits resolution (0-4095). The pin that we have used for this project is GPIO33 (D33). In the “ESP32 WiFi Microphone” project, we have used this channel as the audio signal input. Here’s the project link:…

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…

The main processor of the “1.2-24V Battery Charger Circuit” is ATmega8A. ATmega8A is an AVR 8 bit microcontroller which has 28 pins. This circuit has an internal volt-meter and temperature-meter with digitally calibration feature. The project contains 3 folders, “CodeVision Source”, “PCB-SCH-BOM” and “sim”. There’s a source code folder in this project which contains the…
