Hardware Needed

You do not need all the above mentioned hardware, some of them are optional, which we had mentioned in details in various sections below. learn.edwinrobotics.com

ESP-WROOM-02 Pinouts

It is always important to understand the board which you are working with, is capable of what all stuffs, for this we had added a graphical pinouts and description below: learn.edwinrobotics.com

Circuit Schematics

The ESP-WROOM-02 boards needs few external components to get it working, we had a schematics for ESP-WROOM-02 board below: Now, if you notice in the schematics, we had added pullup resistors on most of the communication lines, if you are not using those pins, you can ignore those resistors. But the resistors on following lines are must to get it wo

Assemble The Circuit on A Breadboard

The first thing in the breadboarding is always begin with Power supply, if you are using breadboard Power Supply module (Refer the hardware needed section) then you do not have to worry much, all you need is battery with DC Jack Male Connector or you might have power adapter with DC Male Jack on it, use it and you are ready to go. Refer the below d

Uploading First Program

Since you are ready with hardware, its time to put the WROOM board into UART Download mode,to do so, all you need to do is: So every time, when you need to upload the code, you have to do this before uploading, this is because the “auto Program” is not implemented in the circuit we built. To do so you need to add some transistors and you need to ma
