In operation

CH340 USB to serial adapter plugged in and connected to the PC. Jumper fitted with ESP-01 board already fitted.

 

Pressing the reset button and then pressing the compile button on the IDE complies the programme and downloads it to the ESP-01 on-board flash.

 

Once programming has finished the jumper is removed and reset button pressed again. Programme then boots up.

 

The ESP-01 will be acting as web interface for the Oil tank monitor, allowing me to interrogate the monitor from anywhere in the house.
