Download the Gerbers or order 10Pcs high-quality boards, for just 5USD.To examine the current consumption of the circuit, I used the Siglent SDM3045X multimeter.ĭistance Data: Centimeters, Inches, Bar Graph To get high-quality PCB boards, I sent the Gerbers to PCBWay and purchased original components using. To design the schematic and PCB, I used Altium Designer 22 and SamacSys component libraries (Altium plugin). The MCU code was developed using the Arduino IDE. Also, a horizontal bar graph provides a visual estimation of the distance. The distance data is displayed on a 128*64 OLED screen, both in centimeters and inches. I used an SRF05 ultrasonic sensor and an ATTiny85 microcontroller. The ultrasonic range finder measures the distance by emitting a 40KHz pulse of ultrasonic sound that travels through the air until it hits an object, then it measures the delay of the reflected signal and sends proper commands to other units. An ultrasonic range finder is a useful tool in a variety of real-life and robotic applications, such as in obstacle avoidance and distance measurement systems.
