Two example sketches of a 2.8 TFT Shield touch screen. A numeric keypad and a basic paint program. These examples have been tested with this screen: TFT: Ilitek-ILI9341 SPI Touch: 4-wire resistive touchscreen attached to STMPE610 controller, but wired as a breakout-board… Tested on both an Arduino Uno and a Leonardo. Download example: tft_example.zip More … Continue reading Touch screen NumPad and Paint example
The ESP32 Wifi module can replace an Arduino, as it has similar properties. Just like the Arduino Nano it can be mounted on a breadboard. This allows building very compact prototype circuits: To get started, Sparkfun’s “ESP32 Thing Hookup Guide” is a good tutorial. I am not going to repeat that. If you want a … Continue reading Getting started with the ESP32 Wifi module
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. This example uses an Arduino Nano, of course you may use an other type of Arduino, eg. the Uno. This guide assumes you already have … Continue reading Connect an ESP8266 module to an Arduino Nano and control it 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
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
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 € 4,85 (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 with … Continue reading Build an RFID reader with Arduino and the RC522 RFID module
Want to use an Arduino to prototype some electronics? But programming is not really ‘your thing’? Consider Modkit, a Visual Arduino Programming tool! This example is a program which makes a led blink, made with Modkit Micro, the free Modkit tool.
As a demo for a workshop I am giving next week, I created a wireless presenter to use for presentations. The receiver is connected to the computer via the Arduino Bit. The wireless presenter is just a button connected to the Wireless Transmitter Bit. When you press the button, the (powerpoint) presentation advances to the next … Continue reading Create a wireless presenter for your presentations with LittleBits
