GROVE STARTER KIT FOR ARDUINO -Girls‘ Day 2026 Workshop

As part of a Girls‘ Day program, my daughter and I are preparing a workshop using the Grove-Starter Kit for Arduino. The Grove Kit comes with several sensors that are easy to connect and a shield to connect these modules directly to an Arduino UNO: When we work with a micro-controller like Arduino, we program…

Bluefruit Interface with Accelerometer and Bluefruit-App

My daughter and I made two interfaces for a theater play using two Circuit Playground Bluefruit from Adafruit and an additional NeoPixel Ring with 24 LEDs (also from Adafruit). All Circuit Playground boards already come with several built-in sensors, LEDs, and a buzzer, which makes it easier and faster to implement into your design. The…

Simple Timer with LEDs and speaker

inspired by the Arduino Starter Kit example #8: ‚The Digital Hourglass‘, my daughter and I made a simple tea timer using two push buttons to enter two different desired times: 3 minutes and 5 minutes. After pressing any of the push buttons all 6 LEDs will light up. Each one of the 6 LEDs will…

Boldport Kits – The Tap and the Cordwood Puzzle Too

Boldport sells many interesting soldering kits, inspired by old famous circuits. We got two of them: We are using „The Tap“ (a touch sensor circuit) to turn on three of the eight LEDs from the „Cordwood Puzzle Too„. The Tap – a touch sensor circuit from 1974 with three touch pads, a reset touch pad…

Counter with 7-Segment-Display and two push buttons

My daughter and I made a simple counter with two push buttons. When you press one of the push-buttons you increase the number shown on the 7-segment-display. When you press the other push-button you decrease the number shown on the 7-segment-display. Material: Video: Hardware: The segments for each digit are small LEDs and they are…

App for Arduino+Bluetooth HC-05

My daughter and I created an App in order to control an Arduino UNO via Bluetooth. The Arduino then controls a servo-motor and an UV LED. The initial idea came from a theater play. Materials: Arduino UNO Bluetooth modul HC-05 ( for +5V) Small Servomotor SG90 UV LED or any other LED Circuit: Pin connections:…

Disco Lights Wearable

Using a Gemma M0 from Adafruit, a Neopixel Jewel and an ALS (Ambient Light Sensor) my daughter and I build up this wearable as Disco Lights. Here is a video: MATERIALS: ° Gemma M0 from Adafruit ° NeoPixel Jewel ° Ambient Light Sensor TEMT6000 ° Conductive Thread to stitch all together on the garment. We…

Greeting Puppy

Here is a prototype for a greeting puppy using an Arduino, an ultrasonic sensor (for the eyes) and a servomotor (for the tail). The puppy will wiggle its tail faster as you come closer 🙂 The hardware connections are as follows: For us it was better to use an extra battery pack for the servomotor.…

Schadensvermeidende Regeln

1. Pluspol (+ rote Kabel) und Minuspol (– schwarze Kabel) von der Batterie sollten sich nicht berühren!!! Achte darauf, dass alle Verbindungen richtig sind bevor du die Batterie verbindest!!! 2. LED immer mit Widerstand verwenden, sonst brennt die LED durch (geht kaputt): 3. Kurze Beine vermeiden das Risiko eines Kurzschlusses und sehen übersichtlicher aus: 4.…

Magic 8 Ball – Arduino Kit Example

The Arduino Starter Kit comes with many examples for beginners. The associated code is included on the Arduino IDE. To open the code on the Arduino IDE, go to: File→ Examples→ 10.StarterKit_BasicKit → … and choose the example you want to work on. For this example we’ve modified the code for the Crystal Ball: The…

Holiday cards with LEDs

If you enjoy tinkering with your kids or on your own, here are some ideas to light-up your self-made holiday cards. You will need some LEDs, copper tape and a CR2032 cell battery. I like to use axial LEDs because they are small and flat, so the card will not look bulky. Also you don’t…

Bluetooth Interface

The main idea of this project is to send some information from your cell phone (through an App) to your Arduino via Bluetooth and then to display this information on an OLED Display. I found this project originally published by circuitdigest.com on how to build a basic Smart Watch Interface easy to follow and well…

Web Server with ESP Boards

There is a website called Random Nerd Tutorials with many cool and well explained projects using Arduino based boards and Raspberry Pi. I am going to share here two of these projects which I followed from their website. The first one is using an ESP8266 Board to control two LEDs from your cell phone, laptop…

LCD-Keypad_Menu to obtain capacitance value

The idea for this project is to simulate the signals going to the relays that activate a capacitance bank. I am using an Arduino DUE and the Adafruit-LCD-Keypad_Board (with I2C). The Arduino receives two inputs: the inductance value L that will be used and the desired resonance frequency f. The Arduino calculates the capacitance value…

Proximity Lamp

This kit from BareConductive contains three lamps to tinker yourself using conductive ink (also included in the kit). There is only one Light Up Board in the kit, so if you want to make three lamps you will have to buy two additional Light Up Boards. For more information visit their website: BareConductive

Wearable with Gemma M0 and Accelerometer

Using the microcontroller board Gemma M0 from Adafruit my daughter and I are simulating gravity on the LEDs of the NeoPixel Ring using an accelerometer LIS3DH. The LEDs will light on, following the inclination of the board: If you hold the board completely vertical and you rotate it, the LEDs will light on individually, changing…

Elektronen-Fänger

Die LED leuchtet, wenn du in der Nähe der Antenne (langes Kabel) deine Haare kämmst oder an einem Wollpulli reibst … oder wenn du elektrostatische Kräfte hast 😉 Materialien: Elektrizität ist keine Erfindung des Menschen, sondern eine in der Natur auftretende Eigenschaft. Besonders anschaulich wird dies, wenn man bei einem Gewitter die Blitze am Himmel…

Math Board (prototype)

Using an AT8951, a 4×4 keypad and two LED dot-matrix this board simulates two basic mathematical functions: Amount Displays randomly the amount represented by any number given by the user between 1 and 99. For example: if you type 27, then 27 dots from the LED dot-matrix will turn on randomly. Every time you press…
