DIY - Voting Machine using Arduino Nano, Copper Tape, OLED

Overview

A simple electronic voting machine where votes are cast by touching copper-tape pads, with live results shown on an OLED display — a hands-on intro to touch sensing and digital input handling.

How It Works

1. Touching a copper-tape pad completes a circuit that the Arduino Nano reads as a vote for that candidate.
2. The OLED display updates the running vote tally in real time.
3. The buzzer sounds briefly to confirm each vote was registered.

FAQ

Do I need coding experience? No prior experience is required — this kit is built around one specific project, and the full code is freely available. See the build guide above.

What tools do I need beyond what's included? A computer with the free Arduino IDE (or ESP32/ESP8266 board support, where applicable) installed to upload the code. No soldering is required for this build.

Can I reuse the parts afterward? Yes — every component in this kit is a standard, reusable part you can use in future projects, not a single-use kit.
