Mini-quad Challenge Gate

thingiverse

The quad mini gate utilizes a laser diode and a light-dependent resistor controlled by an Arduino to identify quads flying through it. When detected, a buzzer sounds and another light illuminates in the Neopixel array. See how many consecutive passes you can achieve without crashing! \nhttps://www.youtube.com/watch?v=YgrbVC4IgLE\n\n \n \n Guidelines\nYou'll require to print out: \n4 Corners \n2 Stands \n2 Swivel Mounts \n1 LDR holder \n1 Laser Diode Holder \nyou'll also need: \nan Arduino \nan LDR (light-dependent resistor) \na 5V laser diode (search eBay for one) \nsome mirror tiles (I sourced mine from HobbyCraft) \nsome 1"x1/4" balsa wood (also from HobbyCraft) \na buzzer \nsome NeoPixels (optional) \nAssemble the parts, align the laser, mirrors and LDR so that the beam bounces up and down and hits the LDR, then secure it in place with glue. \nWire the LDR to a resistor to create a voltage divider, and connect it to one of the analog pins on the Arduino, connect the Laser Diode to 5V (verify it has a built-in resistor) , and link the buzzer up to a digital pin on the Arduino. The attached sketch demonstrates how to read the LDR and perform actions upon detection.
