Then I thought, surely there must be something for the Raspberry Pi here too. After a quick Google search, I found the Shinobi software, which had already been tested on the Raspberry Pi.

Many who have worked with the ESP32 Cam have thought about extending it with a PIR or other sensors. LiLyGo has released a series of cameras, including the current model with a PIR sensor and some other interesting additions.
Continue reading "TTGO T-Kamera ESP32 (V162/V17)"For some ESP projects that work with SD cards, there is an adaptation of the standard Arduino SD library. The classes are usually called MySD and allow other pins to be specified for the SPI interface.

Neatly packaged in a silicone wristband, this is the smallest version of the ESP32 that I know of. The ESP itself does not have its own programmer. However, there is a kit that contains the wristband and a programmer. Once initialised, the wristband can be updated via OTA.

At this point, a rather expensive sensor for around >36€, but one that beats the other distance sensors by „lengths“. I actually wanted to test the I²C version, but the UART version arrived here, which is why I'm presenting it now. (Since I couldn't find any documentation, I'm still not sure if I²C wouldn't also be possible. 🙂)

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.

Here is an acoustic connection for microcontrollers. The KY-038 module houses a microphone and a threshold switch, which can be set via a variable resistor. Both signals, that of the threshold switch and the inverted microphone signal, are provided at pins A0 and D0. WARNING: I was unable to operate this module meaningfully!!! Fact Sheet Description Value Digital...

The HC SR501 is a 360° infrared motion sensor. It has a detection radius of 120°. When movement is detected within the measuring range, it switches a pin to 3.3V and holds it for a set hold time (on-time). Sensitivity and hold time can be adjusted using the respective rotary knobs. Facts Technical Data Description Value Operating voltage 5-20V Current < 60µA Output voltage (on/off) 3.3V/...

I've found a new Arduino UNO clone. While technical data usually tempts me, this time it was the appearance that appealed to me. The board can be had for under £5 from the speedy Ali. Now I have the Arduino clone in my hands and I'm torn. I think it's great that it's discreetly built, but...

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...
