Motor Race Starting Lights

Figure 1 

The project formulates a simple 5 motor racing lights having a start sequence with a random delay which can be used on real race track, kart circuit, and other race circuit.

The operation of the project is simple and involves only the pressing of the start button which causes the LED clusters to turn OFF. They will produce sequential illumination until all five clusters turn ON. The extinguishing of the LEDs signals the start of the race which is determined after a fixed or random time interval. Another race can be initiated to start by pressing the start button again once the LEDs have extinguished.

The random delay and timings are allowed to be customized by the latest version of firmware to suit individual requirements. When the start lights extinguish, a relay, sounder, or other device can be operated or trigger a timing software due to the addition of an output. The 52mm LED clusters were presented in this project along with the software in the PIC microcontroller that allows to operate large LED arrays, low voltage lamps, electro-mechanical relays, or simply small 3/5/8/10 mm LEDs. LED modules are driven by Darlington transistor array.
