# AI electronics project designer with a parts list you can buy in India > Describe a project. Soldr designs it with in-stock parts priced in INR, a power check, pin-by-pin wiring, a schematic and code, shipped across India. [HTML version](https://soldr.ai/ai-electronics-project-designer) [Soldr](https://soldr.ai/) / Tools Describe the project you want to build. Soldr designs it: a parts list of real parts that Compoden has in stock, with prices in rupees, a power check, the wiring pin by pin, a schematic and the code. Buy all puts every part in one Compoden cart, shipped across India. [Start this build on Soldr](https://app.soldr.ai/?prompt=I%20want%20to%20build%20an%20ESP32%20weather%20display%20that%20shows%20temperature%20and%20humidity%20from%20a%20DHT22%20on%20a%200.96%20inch%20OLED) ## What you get from one description - **A parts list** of parts that exist: each one a Compoden product, shown In Stock with its price in INR, and the quantity the build needs. - **A power check:** what every part draws against what the supply and the board's pins can give, including a servo's start-up peak. - **Wiring, pin by pin:** a Wiring Table of every connection for the exact board, and a schematic of the same circuit. - **Code for that wiring:** the sketch is written from the same pin plan, compiled on our server and, for supported boards, flashed from Chrome or Edge on a desktop. ## How it works - **Describe the project** at [app.soldr.ai](https://app.soldr.ai): what it should sense, show or switch, and any parts you already own. - **Soldr picks the board and parts** that are in stock and checks the power. - **It wires every pin** and draws the schematic. - **Generate code** writes the sketch; **Compile** checks it. - **Buy all** puts the parts list in one Compoden cart, or buy only the parts you are missing. ## Why the parts list matters in India A design is only useful if you can get the parts. A parts list from a general chatbot often names modules that are hard to find here, or a variant at a different voltage. Soldr only picks parts Compoden stocks, so the list you see is the list you can order, priced in rupees and shipped across India; COD if checkout offers it for your order. A common start: an [ESP32 DevKitC](https://compoden.com/products/esp32-devkitc-development-board-black-wifi-bluetooth-module), a [DHT22](https://compoden.com/products/dht22-temperature-humidity-sensor-module-accurate-readings), a [0.96 inch OLED](https://compoden.com/products/0-96-inch-oled-display-128x64-i2c-white-ssd1306) and [jumper wires](https://compoden.com/products/jumper-wire-combo-male-to-male-male-to-female-and-female-to-female). ## Boards Arduino, ESP32 and Raspberry Pi Pico builds. Soldr writes code for 674 board targets; ESP32 boards, the Arduino Uno, Mega and Nano and the Pico flash from Chrome or Edge on a desktop, and other boards download for the Arduino IDE or PlatformIO. ## What Soldr checks before it writes code - **Free, safe pins:** no part on a pin the board needs to boot, on an input-only pin, or on a pin already in use. - **Shared buses:** two I2C parts at the same address are told apart. - **Logic levels:** a 5 V part on a 3.3 V board gets a divider or a level shifter, or a note. - **Your own parts:** tell it what you already own and the build uses them instead of adding new ones. The details are in [Wiring & pins](https://soldr.ai/docs/wiring-and-pins). Anything wired to mains voltage needs a qualified electrician. ## What it costs Questions are free. Generated code costs credits, priced by the size of what is written, and a compile costs 5 credits.

Describe the project to Soldr and it returns a parts list of in-stock Compoden parts with INR prices, plus the wiring, a schematic and the code for that wiring. ### Can I buy the parts in India? Every part Soldr picks is one Compoden stocks. Buy all puts them in one cart, shipped across India. ### What if I already have some parts? Say which parts you own and the build uses them; you only buy what is missing. ### Is it free? Questions are free; code and compiles cost credits. Sign in and get 100 credits free.
