Generating variable voltage with Arduino, ESP8266 and ESP32
Let's see how we can generate a variable voltage with Arduino, ESP8266 and ESP32 using different techniques.
Experiments
Electronic charging with MOSFET, easy
We are going to build a constant current variable electronic load, easy and with few components, to do experiments.
PWM driver with MOSFET transistor
Learn how to build, and how it works, a PWM driver with a MOSFET transistor!
PWM driver with BJT transistor
I will explain how to build, and how it works, a PWM controller or driver with a "normal" bipolar transistor.
Sensirion SCD41 and SCD40 CO2 Sensors
This CO2, temperature and humidity sensor is much more than just a pretty face on a slim body...
Experiments with ESPEasy (ESP8266) and low power - v3.0
Getting a low power consumption of our ESP8266 to use it on battery is the goal we want to achieve, and in this article we are going to continue the experiments.
