Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “ DIY RTD for a DMM.” With a fortnight’s struggle, I completed the design of 4 mA to ...

Pinout diagram Wiring configuration to meet the SPE standard You’ll find rather detailed hardware documentation and instructions to get started with the Arduino UNO R4 WiFi, including wiring and ...

This paper proposes a sub-1-V CMOS image sensor using a time-based readout (TBR) circuit. The proposed TBR circuit senses the moment of event from the pixel instead of reading the voltage signal.

Based on the literature survey, we are currently researching and developing the process of controlling the speed and direction of a DC motor using an Arduino Uno microcontroller [7]. It includes an ...

Arduino based Fire Alarm – Circuit and Working Fig. 2 presents the circuit diagram for the fire alarm using a flame sensor and Arduino Nano. The system is powered by a step-down transformer (X1), a ...

Only 63 climate-change interventions led to significant reductions in carbon emissions.

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

Our kit includes the Maker Uno RP2040 itself, four Grove to jumper cables, a USB-A to USB-C cable, a soil moisture sensor with one Grove cable, an HC-SR04 ultrasonic sensor with a Grove cable, a SG90 ...
