Panoramic photo robot with Bluetooth control, based on Arduino MEGA 2560
Since everything in this schematic is either public or super simple I leave it as public too.
**NOT for commercial use!**
This project of mine has just been started so there is no firmware nor software (PC, Android) available yet. Currently I don't plan to make it public like the Arduino shield design.
If you like the s...
Automatic LED Lighting Control of Working Area in the Kitchen and temperature monitoring on NodeMCU with [Cayenne IoT platform].

An Arduino Nano driven CNC controller board for use with the popular
28YBJ-48 (12V or 5V) stepper motors.
These are the schematic and board layouts for the controller board, please
note that there may be a board file with the _fab file name, these contain the
cleaned up silkscreen layers with added information, that is not part of the
The LM236-2.5, LM336-2.5, and LM336B-2.5 integrated circuits are precision 2.5-V shunt regulator diodes. These reference circuits operate as low-temperature-coefficient 2.5-V Zener diodes with a 0.2-Ω dynamic impedance. A third terminal provided on the circuit allows the reference voltage and temperature coefficient to be trimmed easily.
The series is useful as pr...
In this project, I will go through the process of designing and making a flight controller board from scratch for a micro-quadcopter. This board will be based on the ATMega328 microcontroller and will be used to control four coreless DC motors. The whole PCB making process from designing of the schematic to [**custom circuit board**] is done using EasyEDA. If you are interested in the circuit p...
Due to the built-in power switch with a large current, 34063 can control the switch current to 1.5A. The internal circuit includes a reference voltage source oscillator, a converter, a logic control circuit, and a switching transistor.
Reference voltage source is a bandgap reference with temperature compensation. The oscillation frequency of the oscillator is det...
The MP4420S is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It
offers a very compact solution to achieve a 2A continuous output current with excellent load and line regulation over a wide input supply range. The MP4420Shas synchronous mode operation for higher efficiency over the output current load range....
1、Working principle: when the ambient air is normal, the corresponding resistance value of the gas sensitive element QM-2, the resistance in the R3, RW voltage to make the 555 set, 3 pin output high level, the alarm circuit is disconnected, no alarm. Voltage when the detection of gas sensor to gas, liquefied petroleum gas, gasoline, alcohol, smoke and other toxic gases, its resistance decreases,...
This project contains the passive schematic and PCB design for the circuit as simulated in `Bob Pease's High Impedance Active Scope Probe simulations`.
This project contains the passive schematic and PCB design for a simple DIY low frequency high input impedance active scope probe adapter.
It could also be used with a DVM.
I designed a PCB board to be used with the FMC CDU 3D panel by "User0180" on thingiverse (http://www.thingiverse.com/thing:774564). Details on the board can be found here: http://blog.shahada.abubakar.net/post/737-fmc-cdu-pcb-board.
The keys have been designed in a 8x9 "matrix" layout. You should be able to read them and also control the LEDs using any microcontroller (Arduino or Raspberry Pi) o...

Since a lot of our followers asked for a tutorial to guide them to make a basic Robot we decided to provide this instructable that describe a step by step making of **LINE FOLLOWER Robot**, so you will find all the necessary software and hardware parts to make your own Robot following these steps
Note: In this project the main part was made usi...
1、Working principle: CD4060 is composed by an oscillator and 14 binary serial counter bits, the oscillator structure may be RC or is crystal oscillator circuit, Cr (12 feet) high at ordinary times, reset the counters, all counters are mainly from trigger pulses in CP (9-11 foot) decreased along the counter in binary counting.
2、Function Description: adopt CD4060 control 12 red, yellow, and gre...
