Candlestick Chart Price Plotter Kit with Arduino Mega
Master Stock Data Visualization: Candlestick Chart Plotter Kit with Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform raw OHLC stock price data stored on a microSD card into a live, scrollable candlestick chart. The bright 1.8-inch TFT display renders every open, high, low, and close as classic price bars, while three tactile buttons let you step through historical dates. It’s a hands-on way to merge embedded systems with real-world financial data—right from your breadboard.
What You'll Build
A standalone, battery-powered candlestick chart plotter that reads CSV files from an SD card and draws interactive price history. Scroll forward and backward through days of data, with precise date labels and accurate candle scaling. Ideal for visualizing Indian stock market movements, backtesting strategies, or presenting a professional-grade electronics project at Maker Faire or college symposiums.
What You'll Learn
- Parsing structured financial data from CSV files on an SD card
- Drawing pixel-level candlestick graphics on a TFT display using Adafruit GFX library
- Debouncing multiple tactile buttons to create a responsive scrollable UI
- Managing memory and large datasets on the Arduino Mega 2560’s 8 KB SRAM

Who This Kit Is For
This intermediate kit is tailored for CBSE Class 11–12 students exploring data visualization in computer science, B.Tech ECE/EEE undergraduates tackling financial data loggers, and Smart India Hackathon teams needing rapid stock chart prototyping. It’s also an excellent addition to ATL Tinkering Labs and code clubs at IIT, NIT, VIT, and BITS Pilani campuses, bridging electronics with real finance.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to chat with the AI companion trained on this exact kit; it can guide you through wiring, code debugging, and display calibration. If you prefer, message us on WhatsApp for human support.
Can I load my own stock data from NSE or BSE?
Absolutely. Download OHLC CSV data from any exchange, format it with date, open, high, low, close columns, and save it to the microSD card. The firmware parses standard CSV and renders candlesticks automatically.
Does the chart update if I change the SD card data?
The current build reads data at startup and allows scrollable navigation through the stored history. Future firmware updates—available through the AI companion—may add live file monitoring.
Is the display clear enough for classroom demos?
The 1.8-inch ST7735 TFT has a bright backlight and sharp 128x160 resolution, easily visible in indoor lighting for small-group reviews or instructor-led presentations.
