Program of speed and direction control of dc motor
Download as TXT, PDF0 likes132 views
The document contains an Arduino code snippet for controlling a robotic system via Blynk using software serial communication. It initializes pin configurations, handles data from virtual pins (v1 to v4) to control movement directions and speed, and operates motor outputs based on these inputs. The code ensures that only one direction (forward or reverse) is active at a time and provides debugging output through the serial console.
