ESP32 Project: Button, switch, and output screen ?

Post by cv127001 »

Hello,

I'm a beginner with electronics and want to learn by doing a little project and would appreciate your help with parts selection for the project. I already have an Huzzah32 ESP32 Feather from Adafruit. I would like to connect to it an on/off switch, 3 sensor buttons (something easy to push with a finger), and an output screen where I can send some scores to, something easy to output text from the ESP32. By the way, I know my way around with programming.

Appreciate, in advance, any guidance you can give me.

Thank you,

Carlos

Carlos,

You can use a slide switch between the ENable and GND pin to control power on any Feather.

The Huzzah32 ESP32 Feather Learn Guide has some examples using buttons with WipperSnapper which is a good way to get started with input buttons and getting your device on-line quickly.

There are so many display options that you will need to be specific about the desired size, but I'd start with buttons and power first.

Mikey,

THANK YOU so much for helping me get started with the switch and buttons. I like that WipperSnapper - the name too :) .

I've been thinking about the screen, there are two options, but don't know how difficult each option might be. I prefer option 1, but 2 and 3 might be really nice too if not too difficult:

option 1: HDMI output

option 2: small LCD screen (something that fits in the hand)

option 3: some projectors have wifi and/or bluetooth capability to receive video feeds to project.

Thank you for your help, Mikey.

Carlos,

Please take a look at the Adafruit 2.13 FeatherWing eInk displays. They are designed to easily attach to the Huzzah32 and there is a guide for getting it going.

Connecting to HDMI or projectors wirelessly while technically possible is not realistic for this controller. It can be achieved (barely) with some boards, but a Raspberry Pi would make it easy if you want to drive a real monitor or projector.

Mikey,

That tri-color e-ink looks beautiful. Thank you for the guide. I'm going with the tri-color one :).

You have been very helpful. I really appreciate your help. Thank you Mikey.
