Devlog #1 Sonar. Today I built a sonar scanning system using an Arduino Uno, an HC-SR04 ultrasonic sensor, an SG99 micro servo and an 8x8 MAX LED. Compared to some of my bigger builds, this was a much easier project this time around but it was super fun to put together and see working so quickly! Mounted the HC sensor and SG99 servo onto a custom 3D printed (modeled in Onshape). Programmed a continuous 0° to 180° servo sweep in Arduino C++. Mapping angle sweeps across the 8 matrix rows and distance measurements across the 8 matrix rows. Created a GitHub repository with everything and it was almost done only thing left is abit of refining the Case for the HC
