Let’s study artificial intelligence today ! Perceptron First, perceptron is a type of artificial neural network proposed by Frank Rosenblatt in 1957. It is an algorithm that produces one result from multiple inputs. Perceptron can easily be compared to neurons, the nerve cells that actually make up the brain. Neurons receive signals from the dendritic …

Today we will draw a graph using the data from the PMS7003 fine dust sensor. When I compiled the code I uploaded last time, I suddenly got a compile error. While looking for the reason, I found that I did not update the Arduino / Genuino UNO board version. So I entered board manager and …
I post in almost two months. Today’s topic is the PMS7003, a fine dust sensor. Let’s take a look at the contents of the datasheet. PMS7003 is a kind of digital and universal particle concentration sensor, which can be used to obtain the number of suspended particles in the air, i.e. the concentration of particles, …

The ESP-WROOM-32 is a low-power communication module that combines Wi-Fi and Bluetooth. It has an appearance similar to the NodeMCU, and the specification is as follows. There is the pin out of ESP-WROOM-32. You can add it by using the unofficial board URL for use in the Arduino IDE environment, and install it in the …

First, let’s look at the motor driver used. I used the DMD-200 motor driver. The pin map of the motor driver is shown below. The leftmost GND and VCC are the connecting parts of the power supply, and M1 and M2 are the connecting parts of the two poles of the motor. The PWM on …
An ‘oscilloscope’, previously called an ‘oscillograph’ and informally known as a scope or o-scope, CRO (for cathode-ray oscilloscope), or DSO (for the more modern digital storage oscilloscope), is a type of electronic test instrument that graphically displays varying signal voltages, usually as a two-dimensional plot of one or more signals as a function of time. Other signals (such as sound or vibration) can be converted …
The coupling I have is a bending coupling. This coupling is not appropriate because I need a rigid and well-fixed shaft. So I plan to make a rigid coupling with this belt gear fixed shaft. Drill the inner diameter of the coupling to 6mm to fit the motor shaft, and make a 3mm hole in …

Even a scrolling saw can cut carbon pipes, but the vibration is severe and takes a long time. Makita 305MM Slide Compound Mitre Saw 1650W When cut with the Makita blade saw, the noise was very bad, but it was neat and precisely cut, and the length of the saw was lost from the carbon …
