"#379 The All-New Arduino IDE 2.0: Introduction and Test Ten years of waiting has an end. During the Arduino day last week Arduino officially released the beta version of its all-new IDE which should give us all the features of a modern development environment. Without the hassle of a modern development environment. Too good to be true Lets have a closer look. I am a proud Patreon of @greatscottlab @ElectroBOOM @Electronoobs @EEVblog and others.

"#179 Was it worth waiting for Bluetooth How Much Current Needs the ESP32 Bluetooth in BLE Is ESP32 BLE really power efficient How does it compare with Wi-Fi And with a dedicated BLE beacon Power is a precious good in battery powered devices. Today we will investigate how much power a ESP32 burns in normal mode using Wi-Fi or Bluetooth in deep-sleep and in mixed scenarios where it sleeps and sends data every few seconds. The beacon I used contains an N51822 chip Links: BLE Beacon Sketch: https://github.com/ibm-watson-iot/device-arduino/tree/master/samples/ESP32BleBeacon Breakout board:"

"#174 Bluetooth BLE on ESP32 works Tutorial for Arduino IDE Good news My fake Polar H7 Bluetooth heart Rate sensor works on my ESP32 using the Arduino IDE. I will show you what I had to do. And much more Today I can show you - How you can build a sensor which sends data via BLE to a client - A client which can receive these values and display them in Serial Monitor - The mysterious BLE2902 client characteristic configuration and how it works - The details of the protocol used by the heart rate measurement characteristics. This will help you to build other sensors based on different"

We will compare the following sensors: - We will start with the ordinary PIR sensor with [--] pixel - And continue with the AMG8833 which has 8x8 pixels - The next is the MLX90640 with 32x24 pixels - And the last is a Flir One 160x120 pixels camera"
