Learn to Build with
Tishvi Electronics

Full walkthrough for first-time users — install the CH340 driver, set up Arduino IDE, and upload your first Blink sketch. Covers DIP and SMD variants.

Learn how to wire up the HC-SR04 ultrasonic distance sensor to your UNO R3 and write code to measure distances accurately.

Connect and control an SG90 servo motor with your UNO R3 — move to any angle, build a sweep, and start your first robotics project.

Detect objects at 2–10 cm using infrared light. Adjust detection distance with the onboard potentiometer. Perfect for obstacle avoidance robots.

Drive a crisp 128×64 OLED screen over I2C with just 2 data wires. Display text, counters, and sensor readings — no backlight, brilliant contrast.

Control a classic 16-column × 2-row character LCD using the integrated I2C backpack — only 4 wires needed instead of the usual 16-pin parallel connection.

Larger 1.3" OLED with blue-on-black display over I2C. Uses the SH1106 controller — requires the U8g2 library, not Adafruit SSD1306.

Dual-core Wi-Fi + Bluetooth board. Covers 30-pin, 38-pin Micro-USB, and 38-pin USB Type-C variants — Arduino IDE, MicroPython, pinouts, do's & don'ts.

Tiny RISC-V board with Wi-Fi + BLE 5.0 and USB Type-C. Different from the standard ESP32 — no Classic BT, no DAC, and requires USB CDC On Boot enabled.
