HW-103 is a soil moisture sensor with digital and analog outputs. I only use digital output D0 because there is no analig input to RPI 5. First I setup the trimer potentiometer to maximum sensitivi…

VEML 7700 ambient light sensor python program on rpi 5. Display in raw value and can calculate lux from it.

Write few lines on 1.3" oled display SH1106 128x64 pixels using canvas

The program simulates opening and closing a door when sensing a magnet. The sensor has 3 conductors: vcc=3.3V gnd and out connected in this case to gpio pin 27. The performance of the sensor is poo…

When TCS230 is connected to vcc=5v and to gnd the 4 white leds on the module turn on. This program uses only 3 other pins s2=io22, s3=io23 and out=io24. Whenever you put an object in the light of t…

measure temperature (celsius) and magnetic field in micro tesla on python rpi 5

Use GY-2561 to measure infrared radiation on raspberry pi 5 python program. The measurement gives full spectrum and measured IR radiation as low as almost 0 lux.

ADS111r is a four channel A/D connects to I2c on RPI on Python. Since RPI has no analog inputs this is very usefull. This program is measuring only channel 0 out of 0-3 channels. Note that the A-D …

This program is not mine but a copy. It uses AH21B temperature and humidity sensor to display on terminal.

This is not my program but a copy. VL53L0X Laser ranging sensor from 0mm to about 1.5 meters (8190mm is measured if distance is greater than 1.5 meter...). Sometimes it does not measure right so it…

This program is not mine but a copy. Good for 1.3" OLED Display Module Blue color Drive chip SH1106 I2C using canvas

GY 45 accelerometer sensor is based on MMA8452Q chip. This program gives acceleration in 3 axis based on the sensor movement. The zero or standing acceleration is not 000 but values around x: +850 …

measure lux light using opt3001 sensor on python3 rpi 5. the measurements displayed on terminal display

see on screen simple I2c accelerometer and gyroscope measurements on 3 axis. The I2C address of MPU 6050 sensor is 0x68.

Human radar LD2410 connected to UART pins 14,15 on RPI 5. Notice that RX on radar connects to TX on RPI and Radar TX connects to RPI RX. This human radar works on frequency 25ghz with wavelength of…

8bit 7segments lcd display for humidity and temperature based on aht20 sensor. A python on RPi 5 example. Using luma, board, and adafruit_ahtx0 libraries.

This PAJ7620 sensor gives 6 values for gestures: up, down, left, right closing in and moving away. All gestures must be within 25cm range from the sensor. As a reaction to any gesture the MAX7219 d…

on rpi5 python measure distance up to 3 meters with vl53l0/vl53l1x using i2c. Notice that library vl53l0x does not work only library vl53l1x is good

An example of using 1.8 TFT SPI 128x160 display on python/rpi5 using st7735 and gpiozero libraries. The actual maximal size usable is only 125x160 and I am using PIL and st7735 libraries together w…

simple message and clock on 16x2 character lcd as an example of how to use this lcd.

connect to MoSi input gnd and vcc5V (3 contacts) a serie of 64 leds are programmed for all possible colors with ws2812b controller.

A simple program that writes "Hello Yoram" on st7789 240x240 tft display. Use this as an example for your programming.

according to the motion sensor detection of movement the display will show "detect" or "not detect" on display. Only problem is that the motion detector sensor is not so reliable and often shows "d…

a passive infra red (PIR) sensor has two values: human movement detected and not detected. Here I put on a unix terminal display the sensor result.

when an IR proximity sensor (3 pin sensor) is activated the buzzer goes off at 2khz freequency. This is the frequency the buzzer makes the loudest noise.

A moving clock display on 4 8x8 dot matrix display

a weather station based on DHT11 temperature and humidity sensor on ST7735. The ST7735 TFT is a popular, small, full-color display driver chip for microcontrollers, commonly found in 1.8-inch modul…

a very nice clock on 1637 4 digits 7 segments led. the double dots between minutes and seconds blinks every second

A very nice repository for python on RPI 5: one line of time and 2Nd line with date in DDMMYYYY format. The update rate is every 0.3 seconds so every second is on display. Clock is driven from the …

Using adafruit_ssd1306 library display a simple clock for hour and date.
