Lego: build Spike motor chassis

This guide explains how to build a motor chassis, which can for instance be used for the Lego Mindstorms model “Spike” powered by an EVshield with Arduino Uno. Requirements Lego pieces to connect the parts as displayed: Introduction To make a sturdy, compact solution which allows access to batteries, ports and pins of both the … Continue reading Lego: build Spike motor chassis

Touch screen examples: keypad, paint, image viewer and calculator

Some example sketches for a 2.8 TFT Shield touch screen: A numeric keypad, a basic paint program, an  image viewer and a calculator. The shield comes with an SDcard slot. The image viewer reads images from an sdcard. These examples have been tested with this screen: TFT: Ilitek-ILI9341 SPI Touch: 4-wire resistive touchscreen attached to STMPE610 … Continue reading Touch screen examples: keypad, paint, image viewer and calculator

Getting started with the ESP32 Wifi module

The ESP32 Wifi module can replace an Arduino, as it has similar properties. It’s main advantage is that it is faster, has more memory and has WiFi and Bluetooth on board. Just like the Arduino Nano it can be mounted on a breadboard. This allows building very compact prototype circuits: Make module ready for use … Continue reading Getting started with the ESP32 Wifi module

Connect an ESP8266 module to an Arduino Nano and control it with Blynk

We are going to build a circuit that is connected to an app build with Blynk. For this we connect an Arduino to an ESP8266 module and connect it through Wifi (step 1). This example uses an Arduino Nano, of course you may use an other type of Arduino, eg. the Uno. In the second … Continue reading Connect an ESP8266 module to an Arduino Nano and control it with Blynk

Getting started with Blynk

Blynk is an app with which you can control any piece of electronics you have build, eg. a circuit build with an Arduino. To get started with Blynk, you can follow the getting started guide: www.blynk.cc/getting-started then continue at step 5 of docs.blynk.cc (under getting started) to add a first Widget. The first example (BlynkBlink) builds … Continue reading Getting started with Blynk

Build a distance-sensor with LittleBits

By utilizing the Arduino-bit and the Proto-bit, all kinds of electronic circuits and components can be connected to a Littlebits circuit. In this example, we connect an Ultrasonic sensor to the Arduino-bit with the Proto-bit. The distance measured by the Ultrasonic sensor will be displayed on the Number-bit. This example is based on the Bat … Continue reading Build a distance-sensor with LittleBits

Build an RFID reader with Arduino and the RC522 RFID module

The RC522 RFID module is a cheap module which comes with a card and a dongle. You can buy it at our local electronics shop the STORES for a few euro’s (search for ‘rfid’ in the pricelist). Only thing you have to do before you can use it is solder the header. If you are unfamiliar … Continue reading Build an RFID reader with Arduino and the RC522 RFID module
