The coding platform where children build things that are real — programs, robots, circuits, and machines that learn. In a browser. In six languages. Built by Techvein.
A child masters drag‑and‑drop blocks in a term, then has nowhere to go. Hardware kits sit in cupboards because the software that came with them is fragile or expects a technician. Teachers can't tell who is stuck until they walk past. Parents see a certificate and no evidence. Trineetra was built against those four failures — and every feature traces back to one of them.
Blocks at six, Python and C++ at sixteen — in one place, with no migration and no ceiling.
Ten boards, dozens of sensors, one‑click upload from the browser. No IDE, no drivers, no technician.
Live progress, honest observations instead of labels, and curriculum coverage mapped to NEP and CBSE.
Every block program is shown at the same time as Python — and as C++ on Arduino boards. One click opens the full program.
Events, motion, looks, sound, control, sensing, operators, variables and custom blocks.
New learners see nine essential drawers, not thirty. More arrive as a board is connected.
Children who outgrow blocks type real code in the same platform — no migration, no new tool.
Across 9 drawers: Board, Actuators, Displays, Advanced Sensors, Communication, Internet, Face, Companion, 3D World.
English, Spanish, French, Hindi, Marathi and Tamil — the interface and the blocks.
See how a piece of work was built — the attempts, revisions and sittings, not just the file.
Compile and flash over USB with one click — no Arduino IDE, no drivers, no admin rights.
Each board offers exactly the pins its silicon has — Wi‑Fi blocks never appear on a board without Wi‑Fi.
IR, LDR, sound, gas, PIR, rain, soil, DHT, ultrasonic, MPU6050, RFID, fingerprint, servo, relay, LCD, OLED and more.
Readings stream into the blocks on screen, so a program can be watched as it runs.
Every sensor has an on‑screen simulator — a class of forty can do the lesson with one kit, or none.
One sensor kit on the teacher's desk broadcasts live readings to every child's screen.
Turn any phone into a controller and a bag of sensors via a QR code.
Nine studios in one platform — a child moves between them without ever leaving Trineetra.
Sprites, costumes, backdrops, sound, physics and clones — games and animations.
Program a robot and drive it in a simulated arena, then on real hardware.
A photo‑real breadboard where the physics is computed — Ohm's law, series and parallel, polarity — plus a "break my circuit" mode.
Draw a schematic, lay out a two‑layer board, auto‑route copper, run design‑rule checks and export files a real board house accepts.
Design in 3D and export an STL for a school printer, or view it in AR on a phone.
Collect readings, chart them and analyse them as a dataset.
Train image and sound models, use vision and speech, build with face detection and pose — all in the browser.
Build explorable 3D lessons other students can open from a link.
Any phone becomes a controller and a sensor pack, paired by QR code.
Most school coding tools stop where the interesting part begins. Trineetra never runs out of ceiling.
A child moves along one path, and the path decides what comes next — so no one dead‑ends.
Every unit is mapped to formal outcomes across NEP and CBSE frameworks — so a school can show a board or an inspector exactly which requirements a term of Trineetra satisfies.
Three answers before a lesson starts: who needs help now and why, who to pair with whom, and what to reteach — built from what students did, never from labels.
92 lessons across 21 units, each with an intro, a hint, a check and praise — run one having read it that morning.
Set work, track completion and see submissions.
See how the work was built — attempts, revisions and sittings.
Every lesson maps to NEP and CBSE outcomes, with a report on what a class has covered.
Issued automatically on unit completion.
The full path from first block to real hardware — and parents can watch progress.
Lessons that match the syllabus, work that follows them home, and hardware they actually touch.
Ready‑to‑run lessons and a Copilot that answers "who needs me right now?" — no coding background required.
Curriculum mapping, whole‑school reporting, role‑based accounts and compatibility with kits already owned.
Start free, or roll Trineetra out across a school.
Teacher training, onboarding workshops, hardware kits and Techvein Board bundles are also available. Contact us for current pricing.
Start free with no card and no install — or book a demo and we'll plan the rollout for your school.
◆ 15 August 2026No. Trineetra runs in a web browser. Uploading to a real board also happens from the browser — no Arduino IDE, no drivers.
None to start — every sensor has a simulator. When you're ready, Trineetra works with ESP32 (including S3 and C3), Arduino Uno, Nano and Mega, NodeMCU, Raspberry Pi Pico, micro:bit v2, and the Techvein Board.
Yes. Every lesson comes with its own introduction, hint and check, and the Teacher Copilot tells a teacher who needs help and what to reteach. Teacher training is available.
Children keep working. Their work is saved locally and syncs when the connection returns.
Student accounts are created by teachers or parents. There is no public chat, no ads, and no open community feed for children.
Every unit maps to NEP and CBSE outcomes, and the coverage report shows exactly what a class has and hasn't covered.
English, Spanish, French, Hindi, Marathi and Tamil — both the interface and the coding blocks.
