New goodies hit my MailBox, this time from Singapore : Let’s see what’s inside. Short but nice documentation including, schematics, pinout, configuration: YES! It’s a new breadboard adapter for ESP-07 or ESP-12 ESP8266 WiFi module, designed by Baoshi a box containing the module nice packed in antistatic bag. Read more…
One of the desired and also needed things in many projects is the availability of a local display to be able to directly see messages, values, results, etc. What we will need to be able to easy interface it with ESP8266 module is a 3V logic level compatible one and Read more…
——————————— NEW UPADTE —————————————- Added also a new example for a 0-5V input range with Voltage divider and LSB calculation, “the easy way”: ESP8266 internal ADC 2 – the easy way example ———————————- UPDATE ————————————– For a ADC Input Frontend with Auto-range capabilities in the 0-40V Input range take a look Read more…
Just a quick one about new goodies found in the MailBox : External protective envelope Envelope in Bulgarian language:) Have you ever heard about Bulgaria? Is a country in southeastern Europe, member of the European Union, NATO, and the Council of Europe. And why are we interested about? It’s a Read more…
Now, with a nice and powerful 12 bit DAC working on our ESP8266 CBDB Board ( see Part 1 ) let’s test it to the limit a little bit. As you will see from the Oscilloscope and DMM images below, MCP4726 DAC Output it’s nice, smooth and stable. Not bad Read more…
At least from the zillions of request for a DAC Driver implementation example that I received in the latest weeks, this is the long awaited topic: ESP8266 Modules and Voltage Output Digital-to-Analog Converter control! For our project we will use Microchip MCP4726, a Voltage Output Digital-to-Analog Converter (DAC) Read more…
First, The Question: What is a PIR sensor? PIR Sensor with mounted Fresnel Lens A PIR module is basically made of a pyroelectric sensor (see it below as the round metal can with a rectangular crystal in the center), which can detect levels of infrared radiation. Everything emits some low Read more…
