When working with microcontrollers, sensors, development boards, and bare printed circuit boards, most engineers pay close attention to power supply voltage, soldering temperature, component orientation, and signal integrity. One risk, however, is much easier to overlook: electrostatic discharge. A person walking across a floor, moving on a chair, removing packaging, …

The APDS-9960 is probably better known as a gesture sensor. It can detect hand movements such as left, right, up, and down, while also providing proximity sensing. However, the same small module also contains red, green, blue, and clear light-sensing channels. This means we can also use the APDS-9960 as …

Building an Internet of Things project from scratch is a highly rewarding technical challenge. For many hobbyists and developers, the journey begins on a workbench with a simple Arduino, NodeMCU, or ESP32 board wired into a breadboard. Seeing raw sensor data appear on your screen validates hours of hard work …

Adding an antenna to ESP32 can improve Wi-Fi and Bluetooth reliability when the board is installed far from an access point, placed inside an enclosure, or surrounded by components that interfere with its built-in PCB antenna. However, the modification involves more than soldering a piece of wire to the board. …

The ESP32-S3 analog-to-digital converter works well with low-impedance voltage sources. However, problems can appear when the analog signal comes from a high-value resistor divider, a resistive sensor, or another circuit that cannot supply much current. You may notice that the measured voltage is lower than expected, the first reading is …

Tech founders who build custom electronics, IoT projects, and hardware startups often hit a wall when it comes to customer acquisition. Engineering a brilliant product is only half the battle. Scaling market visibility requires a completely different type of architecture, but it is one that modern developers are uniquely equipped …
Read More »Introducing the PIC16F84A Instruction Trace Tool
Learning PIC assembly is easier when you can see what happens inside the microcontroller. The problem is that most tutorials show the instruction, the result, and maybe the affected register, but not the path the instruction takes inside the chip. That is what the new PIC16F84A Instruction Trace tool in PICSimulator.com …
