Product Code: MIKROE-3264

The BarGraph 3 Click Board? is equipped with a five-segment LED bar graph display, notable for its strong and uniform illumination of the segments. Each segment consists of three internal LEDs with a common cathode, while the anodes of all LEDs are connected in a single point. This reduces the number of display bar pins to just six. The common anode is connected to the PWM pin of the mikroBUS via the P-type MOSFET, which can use the PWM signal from the microcontroller to change the intensity of the display. The fact that there are as many as three LEDs per segment makes the segments evenly illuminated, and the red colour of the light on the dark background makes segments visible.
