EAGLE Pattern Gallery
Ultrasonic Range Meter Ver2
On this page, I will introduce the modified printed board pattern for Ultrasonic Range Meter with EAGLE.
The oscillation circuit of the transmitter was added. An oscillation circuit by 555 IC is used for a modified circuit. This is to adjust an oscillation frequency easily. Thereby, it is necessary to change the software.
