Arduino flicker meter-Determining the quality of light bulbs
Incandescent, halogen or fluorescent lamps (as well as LED if poorly designed),turn on and off a hundred times a second and produce light with a flicker at a certain frequency. This simple device can determine the quality of the bulbs, from the point of view of their flicker.

Numerous studies have shown that flickering, Although high frequency and then totally invisible, It can also cause headaches, eyestrain and nausea. Commercial flickering measuring instruments are very expensive (from a few hundred to several thousand dollars), and we can make it for about ten dollars. The code is taken from Electronupdate blog, and instead of APDS9002 ligt sensor I use homemade sensor made of old transistor in metal box BC219. For a sensor you can use almost any transistor with a metal housing to which you will cut the upper part. I also use a 1.3 inch OLED display instead of 0.9 inches for better visibility, with minor code changes.
The device is extremely simple to make and contains only a few components:
- Arduino Nano Microcontroller
- Small 1.3 inch Oled Display with SH 1106 chip
- homemade Light sensor made of an old metal transistor
- and one Button
If we have an oscilloscope, there is a very simple way to test the flickering period and amplitude. All we have to do is connect the sensor directly to the scope without any additional electronics. Due to the nature of the experiment, the light during the shooting can change from very weak to very strong. We will first test the brightness of this battery flashlamp. As we can see, the signal is in the form of a straight line, which is logical considering that the LED is powered by direct current from the battery. Next we will test several types of light sources. I will present it to you in a very general and simplified way so that it can be better understood. In general, the closer the signal shape is to such a straight line, the better the lamp.

Making Windshield Wipers Rock To The Beat
https://hackaday.com/2022/03/31/making-windshield-wipers-rock-to-the-beat/
When you’re driving around, you might occasionally notice your indicators or windscreen wipers sync up fortuitously with the music. [Cranktown City] wanted to ensure his wipers would always match the beat, however, and set about making it so.
After disassembling the wiper motor, The original controller PCB is ripped up, used solely for its home position contacts that help determine the position of the wipers. The battered board is then drilled out to fit a rotary encoder to track the wipers throughout their full motion.
An Arduino is used to read the signal coming from the wiper stalk in order to know what mode the wipers should be in, and uses a motor controller to drive the wipers thusly. It also reads the encoder and home position contacts to track the wiper movement, and uses a proportional controller to control the wiper position. An MSGEQ7 spectrum analyzer is used to track the bass of the music to determine the beat to sync up to.

In this video I will show how to program Coin Acceptor to recognise a set of coins as well as connect it to Arduino .
Arduino code would capture impulses coming from the Coin Acceptor and display the sum of inserted coins on 4 digit display.
We also use Arduino build in EEPROM to save the balance so it is not lost when the arduino is power down.

Mirko Pavleski’s Arduino-powered robot uses a combination of ultrasonic and infrared sensors to track a human and follow them around.
DIY Arduino Human Following Robot © GPL3+
This Robot uses a combination of Ultrasonic and infrared sensors to track an object.
https://create.arduino.cc/projecthub/mircemk/diy-arduino-human-following-robot-24f758
There are several technologies that can detect and maintain a certain distance between a Robot and a Human. The most commonly used are ultrasonic sensors, infrared sensors, laser range sensor, voice and face recognition camera sensors etc..
The robot consists of several components:
- Arduino Uno microcontroller
- L293D Motor driver shield
- 4pcs. DC gear motors with Weels
- HC-SR04 Ultrasonic sensor module
- 2 Infrared sensor boards
- and 7.4 Volts Lithium-Ion Battery pack
To make it, we need only one rectangular plate, on which lower side should be glued the engines, and on the upper surface are mounted other elements. You can use discontinued L293D motor driver shield like in my case, but also and Adafruit motor shield as is presented on the schematic diagram without any changes.

Arduino-controlled CNC engraver uses solar power
https://blog.arduino.cc/2022/04/28/arduino-controlled-cnc-engraver-uses-solar-power/
Usually when we use the term “solar power,” we are referring to indirect energy use: photovoltaic solar panels collect energy from the sun and then either pass it along to a device or store it for later use. But some systems can use power from the sun in a more direct manner. If you’ve ever used a magnifying glass to set fire to a twig, you were using solar power directly. YouTuber Cranktown City pushed that concept further and created an Arduino-controlled CNC engraver that takes advantage of solar power.
This machine doesn’t use energy from the sun to run the gantry motors or even the Arduino Uno board. Instead, it uses the sun and a glass lens in place of a conventional laser.
