Mood lamp is a lamp made from RGB (red, green, blue) led that can be programmed based on its color through remote control, so that the color of the lamp can be determined by the user according to his mood. This lamp is designed using 89C2051 microcontroller with low power technology and uses RGB leds that can be programmed into several colors via a remote control. The remote control signal in this study uses the standard NEC remote code. The results of the led lights experiment can be programmed into 7 colors, namely red, blue, cyan, yellow, magenta, white, and green. The purpose of the results of this study in the future so that it can be used as a business opportunity in the field of creative industries, because this mood lamp can be used as a garden light, home porch lights, restaurants and cafes.

Evaluation Board Microcontroller 89S51 / 89S82 / 89S53 (PEM-51) is a tool used to support microcontroller subject learning with an interactive methodology. PEM-51 consists of input / output modules that are integrated in one PCB board. The modules consist of a switch input, keypad module, LED module, seven segment display module, LCD display module, ADC (Analog to Digital Converter) module, DAC (Digital to Analog Conver) module, Stepper motor module. The software used in this tool is C using the Keil µVision4 compiler. The interactive learning process can be done by making a simulation circuit using Proteus software before implementing it to a microcontroller. With PEM-51, it is expected to increase student competency in studying Microcontroller courses.
