Victory is mine!

I finally got it to work. Took a while, I had to disconnect the I2C SDA/SDL wires and have a pull down resistor on GPIO0 for the ESP-01 to start programming. I got very tired of the Arduino IDE telling me it had a programming error. I have four ESP-01 boards and they all failed consistently. After figuring out the issues, turns out that all four are A-OK.

The bamboo box is a 5V power supply with amp meter that I have plugged into a 3.3V regular on the breadboard.

The ESP-01/OLED is pulling 76mA at that very moment.

Time to build a dedicated ESP-01 programming board and just swap it in and out.

Glad to be of assistance. This method works perfectly, also has the advantage in that by using I2C you can add additional devices to the same 2 wire bus not wasting any more I/O pins

Good luck with your project.
