ESP8266 Microphone (WiFi) With Arduino – Updated

The “Ai Thinker ESP12” module (ESP8266MOD) has an ACD pin (works in range of 0V to 3.3V) with 10 bits resolution (0-1023). The pin is between RST and EN. In the WiFi ESP8266 Microphone project, we have used this channel as the audio signal input. The ESP8266 Microphone Audio Stream Page This page is in…

Over The Air Update

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.…

Make Your Own WiCard On A Breadboard

Like “Arduino”, you can make your own WiCard on a breadboard. If you want to make WiCard on a breadboard before making the PCB, all you need is some resistors and capacitors, a breadboard, wires, an ATMega8a (DIP), an ESP8266 module (with a 32 Megabit flash memory).   The Schematic Here’s the connections guide:  …

WiCard Timer (+Tutorial Video)

WiCard 32 Bit Timer There’s a 32 bit timer counter in WiCard WiFi module. The timer calls its handler function whenever its counter reaches to 0. The unit of the timer counter is micro second (uS). This feature in the current revision is limited. So the real time unit is 1000 uS. That means the…
