Summary of Microcontroller based running light controller
This project is a microcontroller-based running light controller that manages up to 8 bulbs with customizable blinking patterns and speeds. It uses triac-based switching with opto-isolation for safety and includes fuse protection against short circuits. The device operates on 9-12V DC supply and 230V AC load support, with a maximum load of 100W per output. Control is facilitated by three tactile switches to change patterns and adjust speed. Key features include onboard regulation, reverse polarity protection, and standard connectors for power and loads.
Parts used in the Microcontroller based running light controller:
- Microcontroller
- Triac
- Opto-isolator (Opto enabled Triac Control)
- Fuse (F1)
- 9-12V DC power supply
- 230V AC power supply
- Bulbs (up to 8)
- PBT type connectors (CN2 to CN11)
- Tactile switches (SET, UP, DOWN)
- Onboard voltage regulator
- Diodes for reverse polarity protection
- PCB (86 mm x 173 mm with four 3.2 mm mounting holes)
Description
This project provides some lighting effect by the blinking pattern of the bulbs connected at its output. Up to 8 Bulbs can be connected in between connector CN2 to CN9 and AC power to control them should be connected at Connector CN10. DC Power should be applied at Connector CN11 in accordance with the polarity marked on this connector. Care should be taken while using this it as it contains Main Power on the board.
We can change the Blink pattern by the press of the SET switch and change the blinking speed by the press of the UP and DOWN keys on the PCB. Fuse F1 will protect the Kit from any possible short circuit and excess current flowing through it.
Features:
– Microcontroller based design for greater flexibility and ease of control
– Triac based switching of loads connected to the circuit
