Introduction Outdoor IoT solutions depend on a long lasting and stable power supply, but where to find in the wilderness? What immediately comes into mind is battery power, but due to the incompatability between battery voltages and supply voltage of IoT modules like Arduino or ESP8266, a voltage converter is usually part of the circuit, ..

Introduction The Espressif ESP8266-01 module is known for the excessive load it can incur on a circuit. This is particularly true when the module boots up and connects to a WiFi network. This load easily exceeds what the Arduino Pro Mini can provide through its builtin voltage regulator. I destroyed my Arduino module because I ..
Introduction The Espressif ESP8266-01 module is dirt cheap but only has two (four if you don’t need Tx/Rx) digital pins and no analog pins. Nevertheless, it still has its usage if you only need digital I/O. You can control up to four actuators via the digital pins (GPIO set to output) or control the status ..
