Arduino, ESP32 and Raspberry Pi tutorials with a live parts list on every build — one tap puts the whole bill of materials in your cart, shipped across India.
Project of the week
Every tutorial resolves to live stock — the parts list is one tap from your cart.
Build a rain-sensing wiper with an Arduino Nano, a rain sensor, an SG90 servo and a 0.96in OLED — wiring table, full sketch and the failures to expect.
Start here
Each board has its own library of tutorials, troubleshooting guides and pinout references.
The 5 V classic. Tutorials, wiring references and fixes for the board most Indian engineering syllabi still start with.
Start readingNew to ESP32Dual-core, Wi-Fi and Bluetooth for the price of a sandwich. IoT builds, deep-sleep power tricks and the brownout errors everyone hits.
Start readingNew to Raspberry PiLinux on the bench. Camera pipelines, GPIO from Python, headless setups and the power-supply problems that masquerade as software bugs.
Start readingFree tools
The calculators and the code-to-BOM parser run entirely in your browser.

From microcontrollers to motors — sorted the way makers actually build.
From the bench
Troubleshooting, reference pages and full builds — written after the thing actually worked.
Which ESP32 pins are safe to use, which are input-only, which break the boot and why ADC2 stops working the moment Wi-Fi starts. Keep this tab open.
Your ESP32 reboots in a loop and the serial monitor says brownout detector was triggered. Here is what is actually happening, ranked by likelihood.
3 min readWire a soil moisture sensor, a relay and a mini pump to an Arduino so your plants water themselves — with the calibration step most guides skip.
Curated STEM bundles, classroom robotics and bulk component orders — with GST invoicing and dedicated support.
