This laser distance sensor is faster than sonar sensors such as (for example, HC-SR04, US100). It measures in the range of 30mm up to 2 metres and is controlled via the I²C bus at address 0x29. The address can be changed via software.

I had a joystick, an Arduino, and a pan-tilt unit lying around, and I thought I could combine them. See what came of it. Facts This is what I needed: Analogue joystick with two axes Ardurino Uno or similar Pan-tilt with two servo motors Motor control board V1 (practical but not necessary) A few pin header cables Socket...

Here, the assembly and commissioning of the cheap Pan/Tilt kit from AliExpress is described. Pan/Tilt is a platform that can be swiveled in two or more directions using two servos or motors. These are mostly used for cameras but are also very popular in the robotics field. Facts The following components are used for the test…

Using Hall sensors, encoders, or odometry, the revolutions of motor shafts can be counted. The fineness of the count depends on the resolution. I once looked at one of these motors with a Hall sensor, and the results are summarised here. Facts My motor has 6 connections. Two for the motor's 9V supply voltage and 4 for...

I purchased a robot chassis for €89 (this time directly from Amazon). This chassis has three omnidirectional wheels. In this report, I will show the assembly and mention a few facts. The use of the chassis will follow in later reports. (The manufacturer provides an assembly video, which I have linked below.) Facts Components Stable platform made of...

Over lunch with colleagues, an idea struck me. The two of them play chess during their lunch break and to make things a bit more exciting, I suggested a chess clock. This is how the idea of creating a chess clock consisting of two displays for the respective time, two buttons to start and stop the time, and a…
Continue reading "Arduino Schach-Uhr"A new kit from AliExpress has prompted me to build a remote-controlled vehicle. The kit consists of an Arduino, an expansion board, and a PS2 controller with receiver. Components The chassis of the vehicle is formed by a kit from AliExpress LINK. This kit contains an acrylic platform with two motors, wheels, and some accessories. For control, I am using...

Based on my nRF contributions, and with the help of the Sunfounder remote control, I thought it would be nice to build a remote-controlled car out of it. This post describes what came of it. Areas of use: Fun for the kids and the dad 😉 Parts list: Car, drivable chassis, Arduino Uno, Motor Driver Board V2, nRF24 module + breakout board, Power supply…
