Use ADC to listen sound from electret mic and make that to control LED colors. →

Expressif has released a new WiFi chip. It is not that interesting ESP32 that I have written about earlier, and should be available soon. The new ESP8285 went into mass production in March. Hackaday article describes it as ESP8266-Killer, but I I think that this kind of headline is clickbaiting. What could possible make it →

Yesterday I posted about DMX-512 dimmer. DMX-512 is a lighting industry standard way of controlling lighting equipment.DMX-512 allows for one controller (like a lighting desk or computer) to control many lights from many manufacturers. DMX-512 fundamentally provides 512 channels of 8-bit resolution (0-255) level control(which constitue a DMX ‘universe’) using serial  RS-485 communications at 250 →

Some of my favorite small micro-controller platforms (as you might have seen if you have been reading this blog) are Arduino and ESP8266. It seems that there is going ot be some upgrades to those platforms this year. ESP32 ESP8266 chip is used to build  WiFi modules for serial-to-WiFi conversion and Internet of Things applications. ESP8266 →

Espressif ESP8266 WiFi-serial interface : weekend die-shot blog posting shows what is inside ESP8266 WiFi IoT chip. Die size 2050×2169 µm, half of which is occupied by transceiver and PA, 25% – on-chip memory (rough size estimations are ~300KiB), and the rest is Xtensa LX106 CPU core and other digital logic. Chip has marking ESP8089, →

This is the second posting on NodeMcu robot kit: DIY NodeMCU Lua 2WD Open Source ESP8266 WiFi Smart Car Kit. The first posting was a about what you can find inside the kit, and it ended to this picture that shows the parts in the kit When all the parts are now available, the next task →

I like  Internet of Things and robotics, so DIY NodeMCU Lua 2WD Open Source ESP8266 WiFi Smart Car Kit was a good match for this to test. DIY NodeMCU Lua 2WD Open Source ESP8266 WiFi Smart Car Kit is a WiFi RC smart car that is designed and developed based on ESP-12E from ESP8266. It →

Here are two interesting looking ESP8266 projects for controlling mains power: MPDMv3 – WIFI Mains Power Dimmer / Switch – Web Interface Arduino IDE – WIFI MAINS Power Switch – ESP8266 MPSMv2   P3 – WIFI Mains Power Dimmer / Switch with CBDBv2       →
