Thorough understanding of AI-CNN (Convolutional Neural Network)

We will thoroughly understand AI CNN from the basics to practice. We will understand the mechanisms such as how artificial neurons and neural networks, which are the basis of AI, operate. You will also program a convolutional neural network and understand its model and mechanism. Finally, we will use Google Collaboratory and MNIST data to practice the recognition and judgment of mouse handwritten characters.

Illuminance Sensor Investigation (Electronic work) [Which one should I use? ]

When using ESP32, we investigated which illuminance sensor is good. I understand the structure of the illuminance sensor, circuit diagrams, electronic work, and programming. We are confirming whether it can be used for lux measurement using ESP32 and how it can be used for illuminance.

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.

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.

Add Camera to Refrigerator with M5Stack-TimerCamera (Saved on GoogleDrive)

Use M5Stack-TimerCamera to add a camera function to your refrigerator. The captured image is saved in GoogleDrive, and you can check the image in the refrigerator even when you are away from home. Using ReedSwitch, image acquisition and GoogleDrive storage are performed with the opening and closing of the door as a trigger.
