Temperature Controller Server

Embedded Systems & Microcontrollers

It is made on #Arduino. He picked up himself, so he wrote PO, not just "copy-paste". Available on the network, a simple WEB server is lifted, and http gives current temperature on all sensors. It can scan the "net" to the presence of new sensors and gathers infout from all. Almost ready was the GSM module with sending SMS at the alert, but connects not succeeded, went away)

Telegram Crypto Bot — bot for working with cryptocurrency

Embedded Systems & Microcontrollers

Developed a Telegram bot for working with cryptocurrency. The bot allows users to quickly obtain cryptocurrency rates, create buy or sell requests, and track the status of transactions directly in Telegram.

The bot has a user-friendly interface with buttons, automatic notifications, and a request management system for the administrator.

… Bot functionality

• viewing current cryptocurrency rates
• creating a buy or sell request
• request status system
• user transaction history
• notification about request status
• admin panel for managing requests
• automatic notifications to users

The bot helps automate the work of services related to cryptocurrency and simplifies interaction with clients through Telegram.
Technology stack

Node.js, NestJS, PostgreSQL, Prisma ORM, Telegram Bot API, Docker, Nginx.

Manufacturing CAN modules for controlling 2 DC motors up to 24V

Embedded Systems & Microcontrollers

CAN module with opto-isolation, designed to control 2 DC motors with a supply voltage from 6 to 24V, with a current up to 3.5A each.
Also, the board allows connection of four limit switches (for closing).
Enables simultaneous control of 2 motors - rotation in different directions, rotation speed, and quick stop.
It is also possible to connect motors with limit switches to organize movement scenarios.
… All settings are done via the CAN bus.
