| The build consists of three servomotors that independently move three targets up and down, while each target has a photoresistor (LDR) that detects light level changes. There’s also a 7-segment display with four digits that shows the score during the game, a “WIN” or “LOSE” message, as well as an animation and a “3.. 2.. 1.. GO” sequence at the start of the game, which is triggered by the press of a button. Every game event is announced by a passive buzzer, with unique sounds for target hits and misses, game start, win or loss. | The build consists of three servomotors that independently move three targets up and down, while each target has a photoresistor (LDR) that detects light level changes.

| 1. All targets stand in a vertical position and the display shows an animation loop. The ATmega takes a few samples from the photoresistors to determine the reference light level of the room, then the servomotors lay down the targets, preparing for game start. | 1.

| - | 2. Once the button is pressed, a countdown is shown and after it the targets start rising randomly. The microcontroller measures the light continuously, each ADC conversion triggering an interrupt which compares the current result with the reference level. In case of a hit, it commands the corresponding servomotor to lower the target, it activates the buzzer and it increases the player’s score. When the score reaches 10, the game ends, leading to the next phase. If a target was raised and it wasn’t hit in the first three seconds (a time frame that shortens as game time passes), it counts as a miss and the motor lowers it. At three consecutive misses, the game is over. | + | 2. Once the button is pressed, a countdown is shown and at the end of it the targets start rising randomly.
