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…

The NodeMCU board is already known for the ESP8266; now there's also one with an ESP32 Wroom 32. This one doesn't necessarily fit on a breadboard either, unless you can make up your mind about which side of the pins to use ;). This ESP32 board has a CP210 USB bridge, meaning before plugging it into the USB port, have a look at the…

With this board, Funduino offers another RC remote control module. The board features a joystick, various buttons, and connection options for external boards, such as for an RF module, a Nokia display, and a Bluetooth module. Additionally, the board can be operated with 3V and 5V. Intended uses: With an RF module as a remote control for vehicles, with a display as...

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…

The Sunfounder remote control is powered using an Arduino Nano and an nRF24101 board. It has screw terminals for power, a power switch, and two slots for the aforementioned modules. For control, it uses a two-axis joystick, similar to those found in PS4 controllers. The joystick is analogue. Two potentiometers (variable resistors) …

The Arduino Nano is one of the smallest of its kind, but no less powerful. It features an ATmega328 controller from Atmel, and the best part is that it fits on a breadboard. It has 30 connection pins, 15 on each side. For its operating voltage, it requires 7-20 Volts via Vin. However, it can also be powered directly with 5V. Here...

From time to time, I think about starting a mobile project. Usually, I've lacked a use case, the time, and an inexpensive provider for this. Recently, I acquired a Things Mobile SIM card from AZ-Delivery for a grand total of €0. I'm using this first SIM card and its provider as a reason to lay the foundation for projects involving…

The WeMos D1 R32 is an ESP32 housed in an Arduino Uno form factor. It looks like an Arduino, but its I/Os only operate at 3V instead of the usual 5V. This can lead to incompatibilities with expansion boards (shields). The price is under 5 Euros on fast shipping sites like AliExpress. The board features all the advantages of the ESP32 processor…
