To install or add this extensions to your MakeCode editor, click on "Advanced" >> "Add Extensions" in the blocks category. User the keyword "sgbotic" to search for the extension:...

he vRTCam from SGBotic is designed for use with a mobile phone as remote controller with minimum setup. It turns the web browser on your mobile phone into a remote controller. No installation of Apps is required. The vRTCam will function as a wireless access point upon powered up, and uses wifi to link to your mobile phone. Each vRTCam has a unique SSID to allow multiple units to operate in close proximity. This user guide will walk you through the technical aspect of the vRTCam. For application of this module, refer to our step-by-step guide in creating a two-wheels rover using vRTCam . The guide covers hardware assembly, wiring and Arduino programming. Overview & Pinout Arduino Library & Sample Code We have written an Arduino...

The SGBotic Line Follower Array gives your robot the ability to follow a dark line on a white background or vice-versa. This calibrating guide will walk you through the steps in calibrating the IR sensors on the array. Each IR sensor has a LED which turns on when the sensor detects reflected IR light, and a potentiometer for adjusting detecting sensibility. 1. Power the Line Follower Array with 3V or 5V supply. 2. Turn the potentiometer counter-clockwise all the way until you hit a stop. 3. Place a piece of white paper above the IR sensor and turn the potentiometer slowly clockwise until the LED lights up. The height of the paper should be close to your array mounting heights. 4. At this point the IR sensor is calibrated to your desired sensing height. The LED...

STM32 Blue Pill is a feature-rich development board based on STM32F103C8T6 processor - a 32-bit ARM Cortex M3 processor running at 72MHz frequency. Unlike the common Arduino board which is easy to use, programming the STM32 Blue Pill can be confusing especially for a new user. There are several ways to program the STM32 Blue Pill with Arduino IDE - some require external hardware, others just need an USB cable. In the following guide, we will cover three common methods of downloading the sketch in Arduino IDE: Arduino HID bootloader ST-Link compatible emulator and programmer USB to 3.3V TTL adapter So roll up our sleeves and get started. Download and install Arduino IDE The first thing you need to do is to download and install...
