Pachinko 10 million times simulation

Pachinko 10 million times simulation. I want to make sure that "Is it easy to hit a machine that rounds a lot without hitting? What is the distribution graph of the number of rounds and hits?" If there is a 1/319 chance of winning, count the number of times until you get a win, and reset it to zero if you get a win. Perform this repetition 10 million times and check the rotation speed and hit distribution on the graph. In addition, we will check the likelihood of winning by simulation and probability theory.

Motion Sensor Investigation (Electronic work) [What is the first place? ]

We investigated the motion sensors on the market. We will check the specifications of each sensor from the mechanism of the motion sensor, program it, and use it by electronic work. When using the ESP32 for electronic work, we test in enviable environments such as cold objects, small objects, outdoors, and indoors, and evaluate which sensor is the easiest to use and has the best performance.
Electronic work

Humidity Sensor Investigation (Electronic work) [What is the first place? ]

When using ESP32, I investigated which humidity sensor is good. It is a continuation investigation from the temperature sensor. I understand the basic specifications and programming of I2C. We investigated four temperature sensors priced from 350 yen to 480 yen and considered what would be the best overall temperature/humidity sensor.

Temperature Sensor Investigation (Electronic work)
[What is the first place? ]

When actually using ESP32, investigate which temperature sensor is good. We investigated 11 temperature sensors with prices ranging from 40 yen to 480 yen.
