This current sensor amplifier and over current switch project is based on ACS714-30A current sensor and LM358 OPAMP, ½ of LM358 op-amp used as an amplifier for low voltage  and 2nd 1/2 LM358 op-amp used as a comparator which provides over current TTL output, trimmer potentiometer...

The 6 Channel RF Remote Controller designed using CC2500 RF Transceiver modules and PIC16F1847 micro-controller from microchip. Transmitter provided with 6 tact switch, 4 Address Jumpers to pair multiple unit so they don’t interfere with each other. Board provided with power LED,...

Introduction Sometimes it may be necessary to use a display when making a hardware project, but one confusing thing is the size of the display and the required pins to control it. This tutorial will show you how to use a small I2C OLED display with Arduino using only two...

The pressure sensor amplifier built using LM358 op-amp and MPXM2051GS pressure sensor from NXP semiconductor.  The circuit provides 4V output for full scale pressure input 0-7.5PSI.  One op-amp is used as amplifier and 2nd op-amp is used as comparator to provide an output at set...

The serial controlled 50 Segment Bar-Graph Display built using CAT4016 IC. Very useful projects for development Bar-Graph based, Temperature Meter, Interactive Games, Voltage Display, Current Display., Pressure Sensor, Magnetic field meter and PH Meter. Tilt meter, LUX meter. The...

Ιntroduction We covered 4Duino in one of our previous blog posts. 4Duino is a 2.4” Arduino based programmable display module. In our article today, we are presenting a hands-on experience with this product by building a simple project. Many thanks to 4D Systems for sending us a sample...
