What’s inside a counterfeit Macbook charger? After my Macbook charger teardown, a reader sent me a charger he suspected was counterfeit. From the outside, this charger is almost a perfect match for an Apple charger, but disassembling the charger shows that it is very different on the inside. It has a much simpler design that […]

Description This project  will provide 3.3 V @ 800 mA DC Regulated Supply.  The project is based on the LM1117 Low-Dropout Linear Regulator. The LM1117-3.3 is a low dropout voltage regulator with a dropout of 3.3V @ 800mA of load current. Specifications: Input – 5 to 15 VDC Output Current/Voltage 0<Iout<800mA, 4.75V<Vin<12V Output – 3.3 […]

How to interface LCD (Liquid Crystal Display) display module to PIC microcontroller? LCD is a passive component, that is it does not make any light but just modifies the light passing through it for alphanumeric displays. LCD is exclusively manufactured to be used with microcontrollers, which means that it cannot be triggered by usual IC […]

Established and already commercialized energetic materials, such as those based on Ni/Al for joining, lack the adequate combination of high energy density and ductile reaction products. To join components, this combination is required for mechanically reliable bonds. In addition to the improvement of existing technologies, expansion into new fields of application can also be anticipated […]

This is our 8th tutorial of Learning PIC microcontrollers using MPLAB and XC8. We have come up all the way from installing MPLABX to using a LCD with PIC MCU. If you are new here, then look at previous tutorials where you can learn timers, blinking LED, interfacing LCD etc.. You can find all our […]

In Lab 6, we discussed about interfacing a seven segment LED display to a PIC microcontroller. The seven segments were driven individually through separate I/O pins of the microcontroller. If we do just like that then for 4 seven segment LED displays, 28 I/O pins will be required, which is quite a bit of resources […]

Neurotransmitter” cables are used to connect presynaptic axon terminal outputs to postsynaptic dendrite inputs. Blue = Inhibitory , Red = Excitatory . The balance of excitatory and inhibitory input determines if the NeuroBytes fire an action potential or not.The cables plug in with the tab facing away from the board. To unplug, pinch the tab […]

This is our 9th tutorial of Learning PIC microcontrollers using MPLAB and XC8. Till now, we have covered many basic tutorial like getting started with MPLABX, LED blinking with PIC, Timers in PIC, interfacing LCD, interfacing 7-segment etc. If you are an absolute beginner, then please visit the complete list of PIC tutorials here and start […]
