Try to click on and the light will go on or offWhen you have uploaded the sketch, you may remove all the wires required for uploading. This is what is left. ESP8. 26. 6 Wifi Temperature Logger 4 Steps. This is where things got tricky. I spent a lot of time testing different configurations. Note that are two version of the ESP8. The first one has the notification LEDs right next to the board pins. The second one newer has the LEDs by the antenna. I have the second one. The best results came when I loaded V0. Follow these steps to load this firmware. Wi. 07cFirmwareuploadingtool. The best way to test a good connection is by using a USB to TTL cable and using a terminal like Cool. Term. Here is the command to change the baud rate These are the pin connections I used on ESP8. USB to TTL. I used the regulated 3. Arduino to power the ESP8. I know that Arduino vcc 3. A and ESP8. 26. 6 will peak at 2. A. But at the time I had no other regulated 3. Regular usage for the ESP8. A. Remember to connect GPIO0 to GND when you are uploading new firmware. After that remove for normal operation. UTXD RX USB to TTLCHPD lt VCC RST VCC VCC power source GND GND power source GPIO2 GPIO0 URXD TX USB to TTL ote also had to do USB to TTL GND to Arduino GND.
