The Arduino, Bluetooth module (check your specs, some HC-05, and HC-06 may come on a breakout board expecting 5V), and USB Host shield all run off of 3.3V, but devices you want to plug into the ...

4. Connect the breadboard rails to Arduino GND and +5V, and then check that your setup matches that of Figure 10-3. Mounting the Laser For this project, I’ve attached the servos to a pan-and ...

For the quick experiment, I carelessly powered my Tower Pro SG-90 micro servo from the Arduino 5V header pin rather than using a separate power source. Anyway, it is extremely risky going to follow my ...

It is equipped with 32 Inputs (16 x digital 4-30V, 8 x analog 0-10V, 4 x analog 0-5V, 4 x analog 4-20mA) and 20 Outputs (8 x relay 250V/5A, 2 x open-collector 30V/1A, 8 x analog 0-10V) and offers ...

With the Arduino sketches [Jakub] wrote for his load he was able to characterize a pair of Idea batteries and figure out how much charge a three-year-old recyclable battery had.

Nuvoton Technology has announced an Arduino-like development board for its own Arm Cortex-M4 based M467 “Ethernet – crypto microcontroller series”, it calls them. The board, ‘NuMaker-UNO-M4’ has the ...

The wiper of the 10K potentiometer is wired to A0 of Arduino (5V-A0-GND), while anode (A) of the test LED is linked to D5 through a 220Ω-470Ω resistor and cathode (K) to GND.

Arrow has introduced the AXE5000 FPGA Starter Kit, built around the Altera® Agilex™ 5 E-series device. The kit provides a compact platform for evaluating midrange FPGA applications that require ...

I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...

[Vincenzo] wanted to read some 82S129 bipolar proms, and why not, they were very common in the 1980’s arcade scene. The problem is that its kind of an odd ball part now, and typically only (e… ...
